system topology

Low noise, low vibration, light weight, small size, long bearing life, high reliability, and strong versatility
Noise can be reduced by 5-15dB compared with asynchronous motor
Vibration up to class B
Compared with asynchronous motors with the same output power, the frame size is reduced by 1 to 3, and the weight is reduced by about 40%.
Optimize the bearing design, select high-quality bearings, adopt oil-injectable structure for 180 frames and above, and adopt anti-shaft current measures for 250 frames (or 110kW) and above, greatly improving bearing life
High-strength castings and machining precision ensure higher mechanical strength
Implementation of failure rate of quality standard 1000PPM
It can be replaced equally with ordinary asynchronous motors

Compared with asynchronous motor or reluctance motor, the efficiency of permanent magnet motor has little effect on the change of load.
— For variable torque loads (fans, pumps, fluids), constant torque loads (screw compressors, extruders, etc.) are preferred
permanent magnet synchronous motor.
— For project transformation, according to different application scenarios, the newly invested permanent magnet synchronous motor can recover the cost of the whole machine within 1-2 years.
— For new motor projects, the additional investment cost compared with GB3 asynchronous motors of the same power can be recovered within 3-6 months.
