Mine Explosion Evidence Permanent Magnet Synchronous Motor for Scraper conveyor
Solution introduction
PMSM has the positive aspects of simple framework, small dimension, higher performance and large electrical power element.
The everlasting magnet synchronous motor adopts centralized winding, optimal pole slot coordination, and rotor framework integrating isolation, tension, positioning and light-weight, with little rotational inertia, small leakage flux, massive primary flux, greater electrical power aspect and higher efficiency. The torque amplifier coupled with the long lasting magnet motor (planetary reducer) has the attributes of rising the output torque, matching the load inertia, and exclusive use of multi-tooth meshing. Under the control of frequency converter, when the everlasting magnet motor is interconnected with a number of devices, it is simple to realize electricity harmony management owing to the delicate mechanical characteristics.
