Gearless Permanent Magnet Drive Drum

22kw Permanent Magnet Synchronous Motor PMSM Drive

Permanent magnet pulley drive

Product characteristics

(1) High reliability: simple system and gearless drive;

(2) Strong power: the rated torque is provided for starting; the torque overload of three times can be provided theoretically (according to the requirement of order);

(3) Current reduction: the starting current of the equipment is not higher than the rated current; the current is proportional to the load characteristics;

(4) Energy saving: 20%;

(5) Less maintenance: only a small amount of grease is required for the bearing;

(6) Small occupied space: combined with the driving drum of the belt conveyor;

(7) High system efficiency: 90% - 95%;

(8) Low noise: no mechanical transmission ；

4. More than 70 patents

With the unique external rotor permanent magnet technology, Jasung permanent magnet pulley drive shaft is fixed and motionless, which is equivalent to the stator part of the motor. The stator core is fixed on the shaft by the stacking of silicon steel plates, in which the stator windings are embedded. When the stator windings pass the three-phase symmetrical alternating current, the rotating magnetic field can be generated. The surface of the pulley is equivalent to the rotor of the motor. The rotor is fixed on the inner surface of the pulley by superimposing silicon steel plates. It is embedded with ndFeb permanent magnets of UH class, which will generate a permanent stationary magnetic field.When the symmetrical three-phase ALTERNATING current, the motor work, that is, the pulley work.
