Solution Description

Mine Low velocity large torque Explosion Evidence Long term CZPT Synchronous CZPT  

Solution introduction

PMSM has the positive aspects of simple structure, little size, high performance and high CZPT element.
The long lasting magnet synchronous motor adopts centralized winding, best pole slot coordination, and rotor construction integrating isolation, stress, positioning and light-weight, with little rotational inertia, modest leakage flux, large major flux, increased CZPT aspect and increased effectiveness. The torque amplifier coupled with the permanent magnet motor (planetary reducer) has the qualities of growing the output torque, matching the load inertia, and exceptional use of multi-tooth meshing. Below the manage of frequency converter, when the long term magnet motor is interconnected with a number of equipment, it is effortless to understand CZPT balance control due to the gentle mechanical attributes.

AC motors differ from many other types of motors, specifically some of the far more familiar DC (immediate recent) motors, by a number of essential conditions. The most fundamental of these is the fact that an AC motor relies fully on the alternating recent around its circuit to produce efficient mechanical strength. We are going to go over this distinctive method in far more depth in the subsequent sections of this manual.
