The starting torque of the asynchronous motor used in the traditional drive system is usually 55% of the rated torque, which cannot realize the full load starting of the system, while the starting torque of the mine flameproof three-phase permanent magnet synchronous electric drum is the rated torque 220%, when the working conditions need to be started with full load or overload, it can be started directly without manual unloading, so as to avoid motor damage caused by stalled rotor and overload, and greatly reduce the labor intensity of the operator.

Model Description
Easy to install, no need for additional brushing of the wide roadway section, reducing the amount of work;
For multi-point drive belt conveyor, the drive point layout is simple and convenient;
No intermediate transmission link, system efficiency increased by more than 20%, reducing equipment failure and saving power;
The starting torque is 2.2 times the rated torque, realizing heavy load starting;
Professional software is used for electromagnetic, structural and temperature field simulation to optimize the design parameters;
The water-cooling system designed and manufactured with patented technology provides a reliable temperature environment for the permanent magnet drum, and the automatic over-temperature protection provides a solid guarantee against demagnetization;
Equipped with high-quality frequency converter, adopting vector control and master-slave control strategy to realize power balance when working with multiple drives;
The system is maintenance free and the bearings need to be greased only once in 3000 hours of operation;
The use of REMA TIP TOP wear-resistant and flame retardant rubber sheet for the outer covering of the rubber, long service life, maintenance-free.
