Three Phase Asynchronous Motors Classified By Mechanical Characteristics

① Ordinary cage type asynchronous motors are suitable for constant speed operation in places with small capacity and small slip rate changes, such as blowers, centrifugal pumps, lathes, and other low starting torque and constant load situations.
② The deep groove cage type is suitable for places with medium capacity and slightly larger starting torque than the well connected cage type asynchronous motor.
③ Double cage asynchronous motors are suitable for medium and large cage rotor motors. The starting torque is relatively large, but the maximum torque is slightly smaller. Suitable for constant speed loads such as conveyor belts, compressors, crushers, mixers, reciprocating pumps, etc. that require high starting torque.
④ The special double cage asynchronous motor is made of high impedance conductor material. The characteristics are high starting torque, low maximum torque, high slip rate, and the ability to achieve speed regulation. Suitable for punching machines, cutting machines and other equipment.
⑤ The wound rotor asynchronous motor is suitable for places with high starting torque and low starting current, such as conveyor belts, compressors, rolling mills and other equipment.
