Dc motor controller is to control the motor by integrated circuit of the active work, according to the direction of setting speed, Angle, response time. Broader range of application, make motor output more efficient, less noise, etc. But your dc motor controller may encounter failure. The cause of dc motor controller failure generally have the several aspects:
1, the power component damage, generally has the following several possible, motor damage caused by poor quality of the power unit itself or choose level is not enough, the device installation or loosening caused by vibration, motor overload caused by power device driver circuit caused damage or parameter design is not reasonable.
2, the internal power supply damage:
Damage to internal power supply, dc motor controller generally has the following several possible, internal short circuit, the peripheral control unit circuit, external lead to short circuit.
3, intermittent work:
Dc motor controller work starts, generally has the following several possible, the device itself under the environment of high temperature or low temperature drift parameters, overall design controller power lead to some local high temperature device and protection device itself into the state, poor contact.
4, wear cables and connectors or loss caused by poor signal loss:
Connecting the wear and contact the plugin poor contact or fall off, generally has the following several possible, wire selection is not reasonable, the protection of wire rod is not complete, connectors crimping not firm.
Dc motor controller has been applied to industry, the more you use, to all aspects of control of dc motor controller. In particular, the cause of dc motor controller failure. In case encountered at work instead of what to do.
