With no mechanical friction losses from brushes, rated efficiency typically ranges from 85% to 92%, which is 15% to 30% higher than that of brushed motors.
Even under light loads of 20% to 50%, efficiency remains above 80%, making it ideally suited for variable-load conditions and helping to prevent energy waste.
When paired with a high-performance driver, the input power factor can be corrected to 0.95 or higher, significantly reducing reactive power losses in the power grid.

1. Q: What is the difference between a sensor-based brushless DC motor and a sensorless brushless DC motor?
A: Sensor-based motors use Hall sensors to detect the rotor's position, ensuring stable startup at low speeds; sensorless motors rely on back-EMF to calculate the rotor's position, featuring a simpler structure and lower cost, but they have poorer operational stability at extremely low speeds.
2. Q: Can brushless DC motors operate continuously for 24 hours without interruption?
A: Continuous 24-hour operation is supported only within the rated load and rated temperature ranges. For prolonged continuous operation, additional heat sinks or forced-air cooling systems must be installed to prevent damage to the coil insulation caused by excessive temperature rise.
3. Q: What are the temperature rise standards for a qualified brushless motor?
A: Under continuous rated load, the temperature rise at the motor surface must not exceed 25 K above the ambient temperature; a temperature rise exceeding this limit indicates an improper design of the motor's internal magnetic circuit or inadequate heat dissipation.
