SYNCHRONOUS MOTORS MTR3a
Design
Mtr3a reversing synchronous motor is of the permanent magnet type with two stator windings,
for single phase AC 50/60 Hz. Phase displacement of the excitation current is achieved by connecting a capacitor in series with one of the stator windings. The sense of rotation is determined by the resulting circular rotating field. Electrial reversal of the sense of rotation is effected by means of a single- pole changeover switch. The 24 pole rotor which has a steel shaft polished to a mirror-finish rotates in sintered bronze bearings.
Motor can be provided with mounting plate/screw clip for fixing.
