Technical characteristics of Siemens three-phase asynchronous motor

Date:2020-04-20 21:54:51

The Compact series cage type variable frequency speed regulating three-phase asynchronous motor is divided into two rotor structures: cast aluminum and copper bar.
cast aluminum rotor
The N-compact and some H-compact series motors are made of cast aluminum structure:
1. Cast aluminum by die-casting method, with stable and reliable quality;
2. Rotor skewed groove (not twisted), low stray loss, no axial thrust;
3. Satisfactory torque characteristics;
4. Strong overall integrity of the rotor
Copper bar rotor
The high-capacity motors of the H-compact series have a copper bar structure:
1. Flexibly select rotor materials according to requirements;
2. Effectively reduce the production and process preparation cycle of new and special products;
3. High efficiency;
4. The unique copper bar fastening measures of the rotor ensure the tightness of the copper fitting in the rotor slot;
5. Reliable rotor end ring welding technology and process ensure the firmness and uniform mechanical distribution of the rotor cage;
Rotor balance
1. High precision dynamic balancing equipment;
2. Low unbalance quality ensures smooth operation of the rotor and low vibration values for clicking
