Design

The MTR7a a reversing synchronous motor with permanent 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 MTR is operated with single-phase AC current. The same motor version can be used at 50Hz and 60Hz.
