SYNCHRONOUS MOTORS MTR7a
Design
The MTR7a reversing synchronous motor with parmanent magnet rotor 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 MTR7a is operated with singlephase AC current The same motor version can be used at 50Hz and 60Hz.
Application
Reversible power drive for actuators, pumps, label printing machines, medical and optical equipment, office machines, automatic vending machines, machine automation
