Good lubrication is a necessary condition for the normal operation of bearings. For motor products, to ensure the normal operation of the bearing system, it should be analyzed and solved from many aspects such as bearings, greases, and associated parts. In the...

1. Excitation motor: The excitation winding of the DC motor has no electrical connection with the armature, and the excitation circuit is supplied by another DC power supply. Therefore, the field current is not affected by the armature terminal voltage or arma...

Micro DC motors are essentially DC motors. We have introduced it in detail in the previous article. After the motor is powered on, the speed is usually very high, at least a few hundred revolutions per minute, and the higher point can reach tens of thousands o...

A ring-shaped permanent magnet is fixed in the DC motor, and the current passes through the coil on the rotor to generate an ampere force. When the coil on the rotor is parallel to the magnetic field, the direction of the magnetic field will change if it conti...

For the same power of the 3 phase motor, when the torque of the motor is small, the corresponding speed should be fast; When the torque of the motor is large, the corresponding speed is slow. As for the relationship between the two, we used to communicate theo...

Compressor motor current overload is a common but serious problem that can cause a range of adverse effects on a refrigeration or air conditioning system. I will discuss these effects in detail and explore how to effectively deal with this problem. First, let...

In batch production, we often encounter this situation: sometimes different defects appear due to seemingly the same cause, and sometimes the same defect occurs due to different causes. 

Back electromotive force is generated by opposing the tendency of the current in the winding to change. Back electromotive force is generated in the following situations: (1) when an alternating current is passed through the coil;

The characteristics of motor products are the relative stillness of the stator and the relative movement of the rotor during operation. Usually, we use the relatively still parts as the input or output of the power supply.

Deep groove ball bearings cannot bear heavy axial loads, so angular contact ball bearings (also known as thrust bearings) are mainly used as locating bearings in vertical motors.
