Permanent Magnet Synchronous Electric Motor


Permanent Magnet Synchronous Electric Motor


Reversible power drive for actuators, pumps, label printing machines, medical and optical equipment, office machines, automatic vending machines, and machine automation.


MTR8c is a 110V Permanent Magnet Synchronous Electric Motor with power 9.5W speed 375 rpm and torque 10.5 Ncm. It is a reversing synchronous motor with a permanent magnet rotor that is electrically reversible and due to its unique stator design it is moderately priced. The rotating field is produced with a phase-shift capacitor and double-stator with coils thus ensuring extremely quiet running.

Long life is guaranteed by the robust design (sintered bronze bearings; self-centering type). The MTR8C is operated with single-phase AC current. The same motor version can be used at 50Hz and 60Hz. Various windings of motor are available that are tailored to specific requirements. These motors can combined with Spur Gearboxes as per requirement.
