Recently, many customers have contacted us and asked us about the problems they encountered in the use of high-power DC motor, hoping that we can help. Today, we will discuss with you the knowledge of high-power DC motor in these problems, hoping to bring inspiration and help to our customers and let us have a better understanding of high-power DC motor A deep understanding. In this way, we can also be aware of the use of the process in the future, not in a hurry, to play the largest role of high-power DC motor.
1. The damage of power devices may be caused by motor damage, poor quality of power device itself or insufficient selection level, High power DC motor It is caused by device installation or vibration loosening, motor overload, power device drive circuit damage or unreasonable parameter design.
2. The internal power supply is damaged
The damage of internal power supply of high-power DC motor controller generally has the following several possibilities: short-circuit of internal circuit, short-circuit of peripheral control components and short-circuit of external lead.
3. Intermittent work:
The high-power DC motor controller works intermittently, generally there are the following possibilities: the device itself in the high-temperature or low-temperature environment parameter drift, developed DC motor controller overall design power consumption is high, resulting in some parts of the device too high temperature, so that the device itself into the protection state, poor contact.
4. Loss of control signal caused by wear of connecting wire and poor or falling off of connector:
Generally, there are the following possibilities for wear of connecting wire and poor contact or falling off of contact plug-in. The selection of wire rod is unreasonable, the protection of wire rod is not complete, and the connector is not crimped firmly.
