The gap between the stator and the rotor is called the air gap of the motor. If the air gap is too large, the magnetic resistance increases and the excitation current increases, resulting in a decrease in the power factor of the motor. However, the air gap cannot be too small. If it is too […]

The control system of the motor is composed of switches, fuses, main and auxiliary contactors, relays, temperature, and sensing devices, which are relatively complicated. There are many kinds of faults, and it is often necessary to analyze and troubleshoot with the help of control schematic diagram. At ordinary times, attention should be paid to keeping

In the new energy wave that is popular all over the world, the development of new energy vehicle power system can be divided into three stages. The first generation is the central motor centralized drive technology, the second generation is the wheel motor technology, and the third generation is the hub motor technology. Compared with

The motor is composed of a stator frame, windings and insulating materials, a rotor, bearings at both ends and end covers, which is relatively simple. The causes of motor failure are: power supply phase failure, incorrect voltage or frequency; Winding short circuit, open circuit, grounding; Poor operation of the carrier; Dirty inside and outside, poor
