The use of permanent magnet DC motor points

There are obvious differences between permanent magnet DC motor and many motors. First of all, the current it accepts is direct current, which is very different from most alternating current motors. Secondly, the permanent magnet DC motor is also a magnetic motor that establishes a magnetic field to achieve operation through a permanent magnet, so the property is also significantly different from other motors. Unlike some other motors, permanent magnet DC motors are somewhat different in many use techniques.

1, permanent magnet DC motor once the demagnetization phenomenon is not able to operate normally, and other motors in the process of use is not need to worry about this demagnetization problem, so the beginning of the use of permanent magnet DC motor when not paying attention to may lead to demagnetization. For example, during the use of permanent magnet DC motor, it is not possible to use reverse braking under the rated voltage state, which will directly lead to the demagnetization problem of permanent magnet DC motor. If it is necessary to operate in this state, then it is necessary to add a limiting resistor in advance to limit the size of the current.

2, the use of permanent magnet DC motor before the first need to check it, the content of the check mainly includes the appearance of good, smooth coating, transmission components flexibility and so on. In addition, it is necessary to check the power condition of the permanent magnet DC motor to ensure that the practical rectifier will convert the AC voltage to direct current to meet the requirements of the permanent magnet DC motor.

3. When the operating temperature of the permanent magnet DC motor is too high or the current is too large, it will directly lead to the demagnetization problem of the permanent magnet DC motor, so it is necessary to do a good job of the current limiting and overload protection of the permanent magnet DC motor to ensure the normal power and temperature conditions of the permanent magnet DC motor.

Now with the continuous progress and development of technology, the application field of permanent magnet DC motor is more and more broad, with excellent performance of permanent magnet DC motor in the market is still quite popular, our permanent magnet DC motor price is reasonable, excellent performance, powerful, but also quite a reputation of a product, if you want to have further understanding of it, Feel free to contact us.
