Usage Details of Permanent Magnet DC Motors

Permanent magnet DC motor is a popular type of motor in recent years, and its use is also becoming increasingly popular. It plays its value in the form of important machine components, and has become an irreplaceable product. To understand the knowledge of permanent magnet DC motors, one must first start with their usage methods. So next, let's take a look at the usage details of permanent magnet DC motors.

(1) If there is no special instruction for the product, in general, permanent magnet DC motors are not allowed to operate in reverse at rated voltage, otherwise it will cause demagnetization of the permanent magnet. If it is necessary to operate in this way, a current limiting resistor should be added to limit excessive current.

(2) Pay attention to permanent magnet demagnetization caused by excessive current, temperature changes, and open magnetic circuit during disassembly and assembly of the motor. Especially for permanent magnet DC motors, magnetic short circuit protection should be provided for the permanent magnet magnetic circuit during disassembly and assembly, otherwise additional magnetization should be carried out after demagnetization.

(3) When replacing the electric brush, it is necessary to clean the surrounding carbon dust and clean the commutator with alcohol and gasoline. When replacing with a new electric brush, it is important to first perform no-load running in.

When using permanent magnet DC motors, it is necessary to pay attention to many usage details. Only by using permanent magnet DC motors correctly can their value be fully realized. Due to a lack of understanding of the structure of permanent magnet DC motors, the probability of errors occurring during use increases. Therefore, manufacturers using permanent magnet DC motors generally provide skill training to their employees first, which will improve the efficiency of using permanent magnet DC motors.
