Brushless Servo Motor Repair

Brushless motors answer many of the concerns raised by brushed direct current (DC) motors. Brushed motors have existed for over a century, but their brushless successors are only a few decades old. Brushless motors overcome many of the limitations of brushed motors, particularly when it comes to torque. A brushed DC motor will develop a maximum torque level while stationary, and this level decreases as velocity increases.

Brushless motors offer higher performance at a bit of a tradeoff: While a brushless motor is less vulnerable to mechanical wear and tear than a brushed motor, brushless models are a bit more sensitive. Brushless motors use DC electricity to drive the phases of the motor. Permanent magnets create the torque. These motors require more-complex maintenance and are often more expensive than brushed motors. However, brushless motors operate with far less noise than brushed motors and produce more torque per watt of power, leading to greater operational efficiency. They also have a high torque-to-weight ratio, offering more torque in a smaller construction.

What Goes Wrong With Brushless Servos?

Brushless motors typically last longer than brushed motors, thanks to eliminating brush and commutator erosion. Brushless motors produce far less electromagnetic interference. Additionally, we can enclose the entire motor housing completely to protect it from dust, dirt, and debris. Thanks to conduction cooling, the motor doesn’t require internal airflow for cooling.

Most problems in brushless motors arise from heat, which is also the limiting factor when it comes to a brushless motor’s maximum power. Excessive heat will eventually damage the motor winding’s insulation and weaken the permanent magnets. Brushless motors are more efficient than brushed motors, and, while repairs may be more infrequent for brushless motors, the process is far more intricate.
