The cement powder concentrator power assembly is characterized by comprising a mountingbase arranged at the top end of the powder concentrator; the low-speed high-torque amorphous permanent magnet motor is vertically connected with the mounting base; the output shaft of the low-speed high-torque amorphous permanent magnet motor is directly connected with a powder concentrator fan; and a frequency conversion speed regulation control cabinet is connected with the low-speed high-torque amorphous permanent magnet motor. By virtue of the cement powder concentrator power assembly, reactive loss of the motor is lowered, and the motor temperature rise effect can be obviously lowered; compared with the existing permanent magnet motor, the permanent magnet motor disclosed in the invention can save energy by 10-20% provided by detection , so that the motor size can be reduced, the occupied space can be reduced, and the driving assembly is more stable in performance; and by adopting a remote control frequency conversion technology, intelligent operation control is realized.

Description

technical field [0001] The invention relates to the technical field of grading equipment for non-metallic ore powder, in particular to a power assembly of a cement powder separator and a low-speed, high-torque amorphous permanent magnet motor used therein. Background technique [0002] The drive system of the existing cement powder separator adopts a three-phase asynchronous motor to drive the reducer structure. After the reducer is multi-stage variable, the output torque is sent to the powder separator. The structural drive system has defects such as low transmission efficiency, large power consumption, and high failure rate. The driving structure design scheme of using a permanent magnet motor instead of a three-phase asynchronous motor to drive the reducer is applied to the driving operation of the powder separator, which improves reliability and reduces power consumption. However, the stator and rotor iron cores of the existing permanent magnet motors are made of silico...
