Brushless motors do not require brushes and commutators, which are generally considered to be the disadvantages of DC motors, so brushless motors do not require regular maintenance.
Stable speed control possible
Brushless motors continuously compare the set speed with the speed feedback signal from the motor to adjust the voltage applied to the motor; therefore, even if the load changes, it can still adjust from a low speed to the set speed instantly and run at this stable speed. Three-phase induction motors controlled by inverters do not perform feedback control, so the speed will drop significantly when the load increases.
Wide speed control range
The speed control range of brushless motors is wider than that of AC speed control motors and inverters. Since they do not use torque limitation at low speeds like AC speed control motors, brushless motors are suitable for applications that require a certain torque from low speed to high speed.
Helps save energyThe brushless motor uses permanent magnet material in its rotor to reduce secondary losses in the rotor, so it reduces power consumption by about 23% compared to three-phase induction motors that use variable frequency control, contributing to energy conservation in equipment.
Low speed and high torque characteristics
The brushless motor can maintain high torque and run continuously at low speed, and it runs smoothly.

Helps save energy
Since overcurrent, undervoltage, phase loss and other protection functions have been added, the safety of equipment system operation can be protected.
