What are the protection measures for brushless DC motor
Release time: 2020-08-06 10:52:00  Hits: 140

It is not safe if the brushless DC motor is not operated in strict accordance with the instructions. Therefore, we have set up protective measures during production. Next, we will give you a brief introduction:


For the brushless DC motor driver, there are also protective measures, when the load is too large or improper use will cause a large current and the power transistor will be burned. In order to protect the driver from damage due to the current exceeding the specification, it is generally used to increase the power transistor withstand current or add current sensor as protection. Secondly, when the motor load is not small, when the motor stops rotating, the energy and overvoltage returned from the motor end to the driver will endanger the driver, which can be prevented by combining the overvoltage protection circuit and regenerative energy dissipation circuit. The correctness of PWM control can also be affected by the judgment of other Hall sensors, which can be judged by the control unit and warned timely.


About the protection measures of Brushless DC motor, we have won the support and recognition of the majority of users with reasonable price, high-quality service and efficient service. With years of experience and solid foundation, if you need to call, we will serve you wholeheartedly.
