MTR2b is a reversing synchronous motor with power 1W and operating voltage 12V and 24V. It consists of a permanent magnet with two stator windings, for single-phase AC 50/60 Hz. Phase displacement of the excitation current is achieved by connecting a capacitor in parallel with one of the stator windings.

The sense of rotation is determined by the resulting circular rotating field. Electrical reversal of the sense of rotation is effected by employing a single-pole changeover switch. The 12 pole rotor which has a steel shaft polished to a mirror finish rotates in sintered bronze bearings. The motor can be provided with a Mounting plate. These motors can combined with Spur Gearboxes as per requirement.
