Permanent magnet pulley drive



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.



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 ；
