Industrial Fleet Electrification Solutions: High-Torque Electric Drive Systems for Demanding Applications
Industrial fleet electrification is no longer limited to purchasing new electric vehicles. For many companies, a more practical approach is to electrify existing vehicles and equipment by replacing conventional diesel or gasoline powertrains with an engineered electric drive system.
Industrial vehicles often have long service lives, specialized bodies, proven chassis, and highly specific operating requirements. Replacing an entire fleet can therefore involve substantial capital investment and may not always be necessary. With the right electric powertrain, existing vehicles can be repowered for electric operation while maintaining the functions and mechanical characteristics that make them useful.
At CMVTE, we provide electric vehicle conversion systems and electric drive solutions for commercial, industrial, utility, and special-purpose vehicles. Our focus is not simply on supplying an electric motor. We work around the complete propulsion requirement, including PMSM motors, motor controllers, reduction systems, battery systems, charging components, DC-DC converters, and vehicle integration.
Our electric drive systems include 72V, 96V, and 144V PMSM platforms, with power configurations ranging from approximately 11 kW to 65 kW and torque ratings up to 252 N·m. Air-cooled and liquid-cooled solutions are available for different vehicle sizes and duty cycles.
The objective is simple:
Build the right electric drive system for the vehicle’s actual industrial application.
What Are Industrial Fleet Electrification Solutions?
Industrial fleet electrification solutions are integrated technologies and engineering services used to transition a group of industrial, commercial, utility, or special-purpose vehicles from internal combustion engines to electric propulsion.
Unlike passenger EVs, industrial vehicles often operate under very different conditions.
They may need to:
- Carry heavy payloads
- Operate at low speeds for long periods
- Start and stop frequently
- Climb steep grades
- Work continuously for several hours
- Operate in hot or dusty environments
- Tow equipment
- Work inside factories, warehouses, ports, or industrial facilities
- Maintain high torque at low vehicle speeds
For these applications, choosing an electric motor based only on maximum kW is not sufficient.
A successful electrification project should consider the complete relationship between:
Vehicle weight + payload + tire size + transmission/reduction ratio + motor torque + battery voltage + operating cycle
This system-level approach is particularly important when converting existing industrial vehicles.
Why Electrify an Industrial Fleet?
Industrial fleet operators often face several challenges at the same time.
High fuel consumption
Diesel-powered industrial vehicles can consume significant amounts of fuel, particularly when operating under heavy loads or for long working hours.
High maintenance requirements
Internal combustion powertrains contain numerous components that require regular maintenance and can contribute to vehicle downtime.
Environmental requirements
Industrial facilities and fleet operators are increasingly required to reduce local emissions and improve environmental performance.
High cost of replacing specialized vehicles
A purpose-built industrial vehicle may represent a significant investment. Replacing an entire fleet with new electric vehicles may not always be economically practical.
Need for reliable working performance
Industrial vehicles are working assets. They are expected to perform repeatedly and consistently rather than simply provide good performance during a short test drive.
Electrification can address these challenges by replacing the combustion powertrain with an electric system designed around the actual working conditions of the vehicle.
CMVTE Industrial Electric Drive Systems
The electric drive system is at the heart of an industrial fleet electrification project.
CMVTE’s PMSM drive systems provide several voltage and power options so that the propulsion system can be matched to different vehicle sizes and operating requirements.
| Electric Drive System | Power Configuration | Maximum Torque | Cooling |
|---|---|---|---|
| 72V PMSM | 11 / 20 kW | 130 N·m | Application dependent |
| 96V PMSM | 15 / 30 kW | 170 N·m | Air-cooled |
| 96V PMSM | 20 / 40 kW | 210 N·m | Air / liquid-cooled |
| 144V PMSM | 25 / 45 kW | 210 N·m | Liquid-cooled |
| 144V PMSM | 40 / 65 kW | 252 N·m | Liquid-cooled |
The appropriate configuration depends on the vehicle and duty cycle. The figures above should be treated as system selection references rather than a universal specification for every vehicle.
High Torque for Industrial Applications
For industrial fleets, torque can be just as important as power.
Consider a vehicle operating on a construction site.
It may spend much of its working day at relatively low speed while carrying a heavy load. It may repeatedly stop, start, climb ramps, and operate on uneven terrain.
A high maximum-speed specification does not necessarily solve this problem.
What the vehicle needs is useful torque at the wheels.
An electric motor can deliver strong torque from low speed, making PMSM technology suitable for applications where low-speed pulling capability is important.
CMVTE’s drive systems include configurations such as:
- 72V 11/20 kW – 130 N·m
- 96V 15/30 kW – 170 N·m
- 96V 20/40 kW – 210 N·m
- 144V 25/45 kW – 210 N·m
- 144V 40/65 kW – 252 N·m
When combined with an appropriate transmission, reduction gearbox, or axle ratio, these motors can provide substantially different wheel-torque characteristics.
Therefore, motor selection should always be performed together with the vehicle’s gearing and tire dimensions.
PMSM Motors for Industrial Fleet Electrification
CMVTE uses Permanent Magnet Synchronous Motor (PMSM) technology across its electric drive range.
PMSM motors can provide:
- High torque density
- Efficient electric propulsion
- Smooth torque delivery
- Precise speed control
- Compact powertrain packaging
- Strong low-speed performance
These characteristics can be useful for industrial vehicles where available installation space is limited but substantial propulsion performance is required.
However, motor efficiency and performance depend on the complete system. The controller, battery voltage, gearing, cooling system, vehicle mass, and operating cycle all influence the final result.
For this reason, CMVTE approaches industrial electrification as a powertrain engineering project, rather than simply supplying a standalone motor.
Air-Cooled and Liquid-Cooled Electric Drive Solutions
Different industrial vehicles require different thermal management strategies.
Air-Cooled Electric Motors
Air-cooled systems can be appropriate for applications with moderate continuous loads and relatively manageable thermal conditions.
Potential advantages include:
- Simpler system architecture
- Fewer cooling components
- Easier installation
- Reduced system complexity
A 96V PMSM system such as the 15/30 kW, 170 N·m configuration can be considered for suitable light and medium-duty applications.
Liquid-Cooled Electric Motors
Industrial vehicles may operate continuously under high loads. In these applications, thermal management becomes particularly important.
Liquid cooling can be considered for applications involving:
- High continuous load
- Long operating hours
- Frequent hill climbing
- High ambient temperatures
- High sustained torque
- Heavy commercial or industrial operation
For example, CMVTE’s 144V 40/65 kW PMSM with up to 252 N·m of torque provides a higher-output solution for more demanding applications.
The choice between air cooling and liquid cooling should be based on the actual duty cycle rather than motor power alone.
Industrial Fleet Electrification Is Not Just an Engine Replacement
Replacing a diesel engine with an electric motor is only one part of an electrification project.
A complete system may include:
Electric motor
Provides propulsion power and torque.
Motor controller
Controls motor speed, torque, acceleration, regenerative braking, and other operating functions.
Battery system
Stores the electrical energy required for vehicle operation.
Battery Management System
Monitors and protects the battery system.
PDU / High-Voltage Distribution
Manages electrical distribution between major high-voltage components.
DC-DC Converter
Converts high-voltage battery power to the low-voltage electrical system used by the vehicle.
On-Board Charger
Allows the battery to be charged from an AC charging source.
Reduction Gear / Transmission
Converts motor speed and torque into suitable wheel torque.
Vehicle Control and Communication
Integrates the electric powertrain with accelerator input, braking, displays, auxiliary systems, and vehicle communication networks.
The result is a complete electric propulsion system rather than simply an electric motor installation.
EV Conversion for Existing Industrial Vehicles
One of the key advantages of an industrial electrification strategy is the possibility of repowering existing vehicles.
A fleet operator may already have vehicles with:
- Strong chassis
- Usable body structures
- Suitable payload capacity
- Existing industrial equipment
- Established working routes
- Known maintenance history
Instead of scrapping these vehicles and purchasing completely new equipment, an electric conversion can potentially extend the useful life of the existing platform.
A typical conversion process may involve:
Existing Industrial Vehicle
↓
Remove ICE Powertrain
↓
Evaluate Transmission / Differential / Final Drive
↓
Select PMSM + Controller
↓
Select Battery Voltage and Capacity
↓
Integrate Charging and DC-DC Systems
↓
Integrate Cooling System
↓
Install and Test
↓
Validate Performance
The exact process depends on the vehicle and local regulatory requirements.
Applications for Industrial Fleet Electrification
CMVTE’s electric drive systems can be evaluated for a wide range of applications.
Construction and Utility Vehicles
Construction vehicles often require strong low-speed torque and frequent acceleration under load.
Electric propulsion can provide precise torque control and quiet operation while eliminating tailpipe emissions during operation.
Industrial Transport Vehicles
Vehicles operating inside factories and industrial parks can benefit from electric propulsion, particularly where repeated short-distance operation makes centralized charging practical.
Port and Logistics Vehicles
Port and logistics operations often involve predictable routes and repetitive duty cycles.
This can make it easier to develop charging schedules based on actual vehicle utilization.
Municipal and Service Fleets
Municipal vehicles may operate on predictable routes and return to a depot regularly.
This creates opportunities for overnight or scheduled charging.
Agricultural and Special-Purpose Vehicles
Agricultural and special-purpose vehicles can present unique requirements, including high torque, low-speed operation, and extended working periods.
The electric drive system should therefore be selected according to the actual working cycle rather than road-vehicle specifications alone.
How to Select the Right Electric Drive System
There is no single electric motor that is ideal for every industrial vehicle.
Before recommending a system, CMVTE can evaluate information such as:
Vehicle specifications
- Vehicle model
- Curb weight
- GVWR
- Payload
- Tire size
- Existing transmission
- Differential ratio
- Final drive ratio
Performance requirements
- Maximum speed
- Acceleration requirement
- Maximum grade
- Required wheel torque
- Towing requirement
Operating conditions
- Daily operating hours
- Average working speed
- Continuous load
- Ambient temperature
- Terrain
- Stop-and-go frequency
Electrical requirements
- Required battery voltage
- Daily energy consumption
- Required driving range
- Charging time
- Charging infrastructure
This information allows the electric drive system to be selected based on engineering requirements rather than simply choosing the highest available power rating.
From Motor Selection to Complete Fleet Electrification
For a single vehicle, motor selection is important.
For a fleet, standardization becomes equally important.
A fleet may contain several vehicle types. CMVTE can help develop different powertrain configurations around the fleet structure.
For example:
Light-duty vehicles
→ 72V PMSM platform
Medium-duty utility vehicles
→ 96V 15/30 kW or 20/40 kW PMSM
Higher-load vehicles
→ 144V 25/45 kW PMSM
More demanding industrial applications
→ 144V 40/65 kW liquid-cooled PMSM
The actual selection must be confirmed through vehicle-specific calculations and testing.
This approach can help fleet operators establish a more structured electrification strategy rather than developing every vehicle completely from scratch.

We evaluate the vehicle, transmission, gearing, weight, payload, speed, terrain, torque requirement, battery and working cycle as a complete system.
Build an Industrial Electrification Solution Around Your Vehicle
Every industrial fleet has a different operating profile.
The right question is not simply:
“Which electric motor should we use?”
The better question is:
“What electric powertrain does this vehicle need to perform its actual job?”
Whether you are electrifying a single industrial vehicle, developing a pilot fleet, or planning a larger fleet conversion program, the first step is to understand the vehicle and its working conditions.
Provide CMVTE with your vehicle model, weight, payload, tire size, transmission or final-drive ratio, target speed, working hours, terrain, and daily operating requirements.
Our engineering team can then evaluate the appropriate voltage, PMSM motor, controller, gearing, cooling configuration, and battery system for the application.
