Buying Guide: Key Purchase Considerations
- Power needs: Match motor wattage and peak power to the intended load. If you need sustained torque, prefer motors with higher rated torque and cooling features.
- Voltage compatibility: Check system voltage (12V, 72V, 115V/230V) and ensure the controller and battery or power supply align with the motor rating.
- Controller integration: Confirm compatibility with controllers (Fardriver, Kelly, sine-wave) and sensor options (temperature, Hall sensors) for reliable operation and protection.
- Thermal management: Motors with exposed heat sinks or IP ratings benefit longevity; plan for adequate cooling in enclosed or high-load environments.
- Mechanical fit: Check frame size, shaft diameter, and dropout or hub compatibility. Connection to gears, belts, or wheels must align with your project’s geometry.
- Rotation direction and wiring: Reversible CW/CCW capability simplifies installation in certain setups but requires correct wiring and wiring diagrams.
- Protection and durability: IP ratings and insulation classes indicate resistance to dust and moisture; larger applied loads benefit from robust housings and temperature sensors.
