Controller Tips:

  • Match voltage & current ratings with motor specs.
  • Ensure controllers can handle peak currents for acceleration.
  • Look for features like throttle control, regenerative braking, and thermal cutoffs.

8. Safety, Maintenance & Efficiency

  • Cooling: Ensure airflow or heatsinks for >350W motors.
  • Chain Alignment: Misaligned sprockets cause wear and reduce efficiency.
  • Battery Care: Use BMS-protected lithium packs; avoid deep discharge.
  • Brake Safety: Always integrate e-brake or mechanical braking systems for heavier EVs.
  • Periodic Checks: Inspect brushes (DC motors), hall sensors (BLDC), and lubrication in geared units.

9. Future Outlook – Where Small EV Motors Are Heading

  • Higher voltage systems (60–72V) for performance.
