If you own or operate an electric rickshaw in India, you already know how critical the electric rickshaw motor and controller upgrade can be to your livelihood. Whether your existing setup has degraded performance, limited range, or simply can’t handle the load of Indian roads and weather, upgrading the motor and controller is often the most impactful investment you can make. This comprehensive guide walks you through everything — from understanding the components to selecting the right upgrade kit available in India.
Why Upgrade Your E-Rickshaw Motor and Controller?
India’s electric rickshaw market has exploded over the past decade, with over 1.5 million e-rickshaws plying Indian roads. However, many of these vehicles run on low-quality OEM motors and basic PWM controllers that degrade rapidly — especially under the stress of overloading, extreme heat, and poor road conditions.
Here are the top reasons Indian e-rickshaw operators upgrade their motor and controller:
- Reduced range over time: Degraded motors draw more current for the same output, draining the battery faster.
- Overheating issues: Low-quality motors with poor winding insulation fail in Indian summers.
- Slow acceleration: Original controllers often have conservative current limits that throttle performance.
- Hill climb struggles: Under-powered motors strain on inclines common in cities like Pune, Shimla, or Bengaluru.
- High maintenance costs: Frequent brush replacements and winding repairs on brushed DC motors add up fast.
Upgrading to a higher-wattage BLDC motor with a compatible sinusoidal controller can recover lost performance, extend battery life, and significantly reduce maintenance.
Types of Motors Used in Electric Rickshaws
Understanding which motor your e-rickshaw uses is the first step in planning your upgrade.
1. Brushed DC Motors (Older Models)
Most early e-rickshaws (pre-2018) used brushed DC motors in the 650W–1200W range. These are simple and cheap but require frequent brush maintenance. They are progressively being phased out in favor of BLDC motors.
2. BLDC Hub Motors (Current Standard)
Most modern e-rickshaws use rear-wheel BLDC hub motors ranging from 800W to 1500W. These are brushless, more efficient, and nearly maintenance-free. Popular wattages in India: 850W, 1000W, and 1200W.
3. Mid-Drive BLDC Motors (Premium)
Less common in rickshaws but increasingly used in performance builds, mid-drive motors deliver torque through the drivetrain, offering better hill-climbing. They are more expensive (₹12,000–₹25,000) but offer superior efficiency.
Brushless Motor Advantages for Indian Roads
- No brushes to replace — reduces maintenance stops
- Higher efficiency (85–92% vs 70–80% for brushed)
- Better thermal performance with proper controller tuning
- Compatible with regenerative braking controllers
Understanding the Controller: The Brain of Your E-Rickshaw
The motor controller is equally important as the motor itself. It converts DC battery power into controlled current for the motor and handles throttle, braking, and regeneration. In India, most stock e-rickshaws use basic square-wave (6-step) controllers that create torque ripple and heat issues.
Square Wave vs Sinusoidal Controllers
| Feature | Square Wave | Sinusoidal (FOC) |
|---|---|---|
| Efficiency | 75–82% | 88–94% |
| Noise | High | Low |
| Heat Generation | High | Low |
| Cost | ₹800–₹2,500 | ₹2,500–₹8,000 |
| Regen Braking | Basic/None | Yes (5–15% range recovery) |
For a serious e-rickshaw upgrade in India, a 48V 40A or 60V 45A sinusoidal controller is the recommended choice. Brands like KT, Sabvoton, and Votol are popular among Indian EV mechanics.
Key Controller Parameters to Match
- Voltage rating: Must match your battery pack (48V, 60V, or 72V)
- Phase current: Should be 2–3x motor rated current for good torque
- Hall sensor compatibility: Most Indian hub motors use 5V Hall sensors (120° spacing)
- Waterproofing: Look for IP65 rating minimum for Indian monsoon conditions
Choosing the Right Upgrade Specs for Indian Conditions
Indian e-rickshaws operate under unique conditions: heavy payloads (300–600kg including passengers), potholed roads, temperature extremes (0°C in North India winters to 48°C in Rajasthan summers), and frequent stop-and-go city traffic.

Step-by-Step Upgrade Process
Before starting, ensure you have basic electrical tools: a multimeter, wire strippers, soldering iron, heat-shrink tubing, and terminal crimpers.
- Disconnect the battery: Safety first — disconnect the main battery positive terminal before any work.
- Remove the old motor: For hub motors, this involves removing the rear axle nuts, disconnecting phase wires and Hall sensor connectors, and pulling the wheel.
- Install the new motor: Seat the new hub motor, torque the axle nuts to spec (typically 80–100 Nm), reconnect phase wires matching colors (or use a multimeter to identify correct phasing).
- Mount the new controller: Find a cool, dry location — ideally with airflow. Secure with rubber vibration mounts to reduce mechanical stress.
- Wire connections: Connect battery, phase wires, Hall sensors, throttle, brake levers, and (if applicable) display. Double-check polarity.
- Initial test: Reconnect battery, engage power slowly via throttle. Check for proper rotation direction — if reverse, swap any two phase wires.
- Parameter tuning: For FOC controllers with PC/Bluetooth interface, tune phase current limit, speed limit, and regenerative braking strength to your preference.
- Road test: Test under load, check for overheating after 15 minutes of operation.

Frequently Asked Questions
Can I upgrade my e-rickshaw motor without changing the controller?
Technically yes, but it’s not recommended. If you install a higher-wattage motor with the old controller, the controller may not supply enough current for optimal performance, or it may overheat and fail. Always match the controller rating to the motor.
Is it legal to upgrade an e-rickshaw motor in India?
Electric rickshaws are regulated under the Central Motor Vehicles Rules. Modifications that change the rated power of the vehicle require re-certification from a testing agency. However, like-for-like replacements (same wattage, voltage) are generally done without re-certification in practice. Always consult your local RTO.
How long does a quality BLDC motor last in an e-rickshaw?
A quality BLDC hub motor from a reputable brand, paired with a properly tuned controller, can last 3–5 years or 50,000–80,000 km under normal Indian operating conditions. Regular bearing inspection and waterproofing maintenance extends lifespan.
What’s the best battery voltage for a rickshaw upgrade — 48V or 60V?
60V systems are increasingly popular for upgraded rickshaws as they offer better hill-climbing torque and higher top speed without requiring excessively high current (which causes heat). 48V is fine for flat terrain. 72V is used in performance builds.
Where can I buy e-rickshaw motor and controller components in India?
Online electronics stores like Zbotic.in offer motors, ESCs, and related components. For complete e-rickshaw-specific kits, wholesale EV parts suppliers in Delhi’s Karol Bagh, Mumbai’s Dharavi, and Bengaluru’s SP Road are popular sourcing points.
