When sourcing motors for electric or CNG auto rickshaws, you must prioritize Power Rating (typically 3kW to 10kW) and Voltage compatibility (48V, 60V, or 72V). For electric versions, BLDC (Brushless DC) motors or PMSM (Permanent Magnet Synchronous Motors) are preferred due to their high efficiency (up to 90%+) and low maintenance. Ensure the motor provides sufficient Peak Torque to handle full passenger loads and steep inclines, and verify the IP67 waterproof rating to ensure operational reliability during rainy seasons or flooded road conditions.
