Beside PMSM and AC 3-phase Induction Motor, a BLDC motor (Brushless DC Motor) is also widely used motor types for electric cars today. Here’s a clear breakdown:
🔹 What is a BLDC Motor?
Brushless DC Motor uses electronic commutation instead of brushes, making it more efficient and durable than traditional brushed motors.
It runs on DC power (from the battery) but uses an inverter/controller to convert it into a three-phase AC signal for smooth operation.
🔹 Advantages for Electric Cars
High Efficiency (85–95%) – Better use of battery power, longer driving range.
High Torque at Low Speed – Great acceleration, no need for a traditional gearbox in many cases.
Compact & Lightweight – Fits well in limited vehicle spaces.
Low Maintenance – No brushes to wear out, longer lifespan.
Regenerative Braking – Can recharge the battery while slowing down.
🔹 Typical Specs for EV BLDC Motors
Power range: 5 kW (small cars/golf carts) up to 100+ kW (sedans & SUVs).
Voltage: 48V–800V depending on vehicle size.
Cooling: Air-cooled for small cars, liquid-cooled for high-performance EVs.
Applications: Conversions (small cars, classics), factory-built EVs, off-road buggies, motorcycles.
🔹 Why Many EV Conversions Use BLDC
BLDC motors strike the right balance between performance, cost, and reliability. They’re more affordable than AC induction motors, while still providing enough power and efficiency for most passenger cars.
5KW 72V motor
A 5 kW 72 V BLDC motor is a compact but powerful option, often used in small electric cars, tricycles, golf carts, and light utility vehicles. Here’s a quick profile:
🔹 Key Specifications (Typical)
Rated Power: 5 kW
Voltage: 72 V DC
Current: ~70–90 A (continuous, peak may be higher)
Efficiency: 85–92%
Speed Range: ~3000–5000 rpm (depending on winding)
Torque: 15–25 Nm (varies with gearing)
Cooling: Air-cooled (sometimes optional liquid cooling)
Controller: Must be paired with a compatible 72 V BLDC controller/inverter
🔹 Applications
Small EVs (microcars, neighborhood vehicles)
Three-wheelers / tuk-tuks / e-rickshaws
Golf carts & utility carts
Light off-road buggies
Small boats (electric propulsion)
🔹 Advantages
✅ Compact size, light weight
✅ Strong low-end torque (good for city driving)
✅ Compatible with 72 V battery packs (common Li-ion or lead-acid)
✅ Cost-effective for entry-level EV projects
👉 If you’re thinking of using this for an EV conversion, you’ll need not only the motor, but also a 72 V controller, throttle, battery pack, and BMS.

3KW 60V motor
A 3 kW 60 V BLDC motor is a smaller, efficient motor widely used in light electric vehicles. Here’s a compact overview:
🔹 Key Specs (Typical)
Rated Power: 3 kW
Voltage: 60 V DC
Current: ~50–70 A (continuous)
Efficiency: 85–90%
Speed Range: ~2500–4000 rpm
Torque: 10–18 Nm (can be boosted with gear reduction)
Cooling: Usually air-cooled
Controller: Needs a matching 60 V BLDC controller
🔹 Applications
Electric motorcycles & scooters 🛵
E-rickshaws & three-wheelers 🚖
Light quadricycles & neighborhood EVs 🚙
Golf carts & small utility vehicles 🛺
Small boats or industrial carts ⚙️
🔹 Advantages
✅ Good balance between power and efficiency for small vehicles
✅ Compact, lightweight, and low maintenance
✅ Pairs well with common 60 V lithium or lead-acid battery packs
✅ Affordable entry-level EV power solution
👉 A 3 kW 60 V setup is best for vehicles needing 50–70 km/h speed and moderate load carrying.
