When choosing an electric motor or EV conversion kit for a Classic VW Bus (T1/T2), We can consider following :
| Parameter | Importance | Typical Target |
|---|---|---|
| Power (continuous/peak) | Determines acceleration & top speed | 50–100 kW continuous is common for daily use |
| Torque | Crucial for low-speed start & hill climbing | Higher torque = smoother drive |
| Voltage | Must match motor, controller, and battery | 72 V, 96 V, 144 V, or higher |
| Cooling | Air vs. liquid cooling | Liquid recommended for sustained load |
| Mounting/Adapters | Must fit original gearbox/axle | Often needs custom adapter plates |
| Controller/Drive electronics | Must match motor & voltage | Should include regen braking if possible |
| Battery system & layout | Weight, distribution, safety | Needs reinforced mounting |
| Certification & safety | Road legality | Local regulations apply |
Recommended Motor Size
Daily driving / classic feel → 25–70 kW continuous, 50–150 kW peak
Voltage choice → 144 V-360V systems are most common for VW conversions
Torque priority → Choose motors with strong low-RPM torque to match the Bus’s weight
144V 25kW PMSM Motor
Selecting a 144V, 25kW system for an electric vehicle (EV) conversion is a deliberate choice that prioritizes cost, simplicity, and specific use-case functionality over high performance and long range. Here's a breakdown of the reasoning:
1. The Voltage (144V): A "Low-Voltage" System
Safety and Simplicity: A 144V system is often classified as a "low-voltage" or "traction voltage" system in the EV world. It is significantly safer to work on for hobbyists and DIY converters compared to modern high-voltage systems (300V-400V+). It requires less stringent safety gear and insulation.
Component Availability and Cost: Components like DC motors, controllers, contactors, and DC-DC converters for this voltage range are widely available, proven reliable, and generally much less expensive than their high-voltage AC counterparts.
Battery Pack Assembly: Building a 144V battery pack is straightforward. For example, using 3.2V Lithium Iron Phosphate (LiFePO4) cells, you would need:
144V / 3.2V = 45 cells in series.
This is a manageable number for a custom pack build.
2. The Power (25kW): Prioritizing Utility over Performance
Adequate for the Application: A 25kW (approximately 33 horsepower) DC motor produces high initial torque, which is excellent for getting a laden vehicle moving from a stop. This makes it surprisingly adequate for specific, limited-use cases:
Urban Delivery Van: Perfect for low-speed, stop-start "last-mile" delivery in a city where top speed is not a priority.
Airport/Factory Ground Vehicle: Ideal for moving cargo short distances on private property with low speed limits.
Short-Range Commuter: Sufficient for very short daily commutes on low-speed roads.
Cost Efficiency: A 25kW system is one of the most affordable entry points into an EV conversion. The motor and controller combo is cheap.
Energy Efficiency (at low speeds): For its intended low-speed purpose, it can be very efficient. The system has fewer losses than a high-power AC system when not driven hard.

336V 32kW PMSM motor+controller （2 in 1）
For users who demand stronger acceleration and more dynamic performance, our 32kW PMSM is the top choice. Designed to deliver higher torque and greater power output, it transforms the BUS into a vehicle that not only meets but exceeds expectations for electric conversions.
With robust peak torque, this motor ensures quick response when accelerating, overtaking, or climbing steep roads. It is especially suitable for drivers who regularly face demanding conditions or prefer a sportier driving experience. Despite the higher power, the 32 kW motor maintains efficiency through advanced design, ensuring that energy use is optimized.
While slightly larger than lower-rated motors, its installation remains straightforward, and the extra capability provides long-term driving satisfaction. Customers who want their VW BUS conversion to deliver strong, confident performance will find the 32 kW option the most rewarding. It strikes the perfect balance between modern electric efficiency and the excitement of enhanced driving power.

360V 68kW PMSM motor
Performance Expectations with 68 kW Motor to convert with the VW BUS T1/T2
Assuming the Bus weighs ~1,600-1,800 kg with driver and some luggage:
Acceleration: Much better than stock. 0-60 km/h might be brisk if torque is good, but expect modest 0-100 km/h times compared to modern EVs.
Top Speed: Depends on gearing. With proper gearing and power, you might get 100-120 km/h (~60-75 mph) comfortably, but pushing beyond that will reduce efficiency.
Range: Highly dependent on battery. Rough ballpark: with a 40-50 kWh pack, maybe 220-250 km under mixed driving, less if highway.
Efficiency: Older VW Buses are not aerodynamic; expect higher drag, especially at highway speeds. Battery weight increases rolling resistance. Energy consumption will be higher than a streamlined EV.
