Vibration and noise are important performance indicators of motor products, and vibration and noise are two accompanying physical phenomena. There are three main types of motor noise, namely electromagnetic noise, mechanical noise, and ventilation noise.

Winding temperature rise is a key performance indicator of motor products and plays a vital role in the reliability of motors. Factors such as the motor itself, the operating environment, and load changes will all cause changes in the motor's temperature rise level. When the temperature rises, does it always show an increase in current? This is also a question worth exploring.

During the operation of a motor, the most ideal state is to have the stator and rotor iron cores axially aligned, ensuring maximum effective iron length. However, in practical situations, due to the heat generated during motor operation, components will expand and thus require determining the movable end and the fixed end according to the actual structure of the motor, leaving necessary axial clearances. In addition to normal thermal deformation, misalignment of the stator and rotor iron cores can occur during motor operation due to magnetic forces, leading to axial movement of the motor rotor. The direct consequence of this issue is misalignment between the stator and rotor, resulting in axial forces on the bearings.

The stator winding of a three-phase induction motor is powered by a three-phase AC power supply, and the current in the rotor winding is generated by electromagnetic induction, thus converting electrical energy into mechanical energy.

The highly anticipated 134th China Import and Export Fair, commonly known as the Canton Fair, returned to Guangzhou with great fanfare, proving once again its significance as a leading global trade event. From October 15 to November 6, the Fair showcased the resilience and adaptability of international business communities amid a rapidly changing global landscape.

The three-phase AC asynchronous motor is a widely used electrical motor in various industrial and commercial applications. As the name suggests, it operates on the principle of induction, where the rotation of the motor is not synchronized with the frequency o...

The first type is a split phase starting type, as shown in Figure 1, which is assisted by an auxiliary starting winding and has a small starting torque. The operating speed remains roughly constant. Mainly used in electric fans, air conditioning fan motors, washing machines and other motors.
