    Brief Description of the Reasons for the Failure of DC Motor Controller
    2018/11/23 12:23:09

    The DC motor controller controls the motor according to the set direction, speed, angle and response time through the active work of integrated circuit. The motor has the advantages of wider application range, higher output efficiency and less noise. But the DC motor controller will also encounter faults. There are generally several reasons leading to the failure of DC motor controllers:

    1. Damage of power devices is generally caused by the following possibilities: motor damage, poor quality of power devices themselves or insufficient selection level, device installation or vibration loosening, motor overload, power device driver circuit damage or unreasonable parameter design.

    2. Damage of internal power supply:

    The damage of internal power supply of DC motor controller generally has the following possibilities: short circuit of internal circuit, short circuit of peripheral control unit and short circuit of external lead.

    3. Intermittent work:

    DC motor controllers work intermittently. Generally, there are several possibilities as follows. The device itself drifts in high or low temperature environment. The large power consumption of the overall design of the controller leads to the excessive local temperature of some devices, which makes the device itself into a protective state and poor contact.

    4. Loss of control signal caused by abrasion of connection line and bad or falling off of connector:

    Connecting wire wear and contact plug-in bad contact or fall off, generally there are the following several possibilities, wire selection is unreasonable, wire protection is not complete, connector pressure is not strong.

    DC motor controller is constantly used in all aspects of industry. The more it is used, the better it is to master all aspects of DC motor controller. Especially the cause of failure of DC motor controller. In case of encounter in the work, but helpless.
