BAIXIANG MOTOR CO.,LTD.

1. When the load is too large or improper use will cause a large current and the power transistor burned. In order to protect the driver due to the current exceeds the specification, it is generally used to increase the power transistor current resistance or add current as a protection.

2. When the DC motor load is not small, when the DC motor stops rotating, the energy and overvoltage sent back to the driver by the DC motor will endanger the driver, which can be prevented with the overvoltage protection circuit and the recovery energy dissipation circuit.

3. Other normal or not will also affect the correctness of the control, which can be judged by the control department and timely warning.
