The paper presents results of field calculations for a single phase capacitor motor with tapped stator windings. The Sh71-2A motor magnetic circuit windings for two speeds were designed. The 2D computational motor model was worked out and calculations of the motor transient state during starting were performed. The quasi-static motor characteristics for two connection systems were determined. Computation results of the starting torque as a function of the rotor position at the locked rotor are presented. The static characteristics computed are compared with the measurement results of a prototype motor.

This article deals with calculation results of a two-speed synchronous, silent-pole, high power motor. Two-speed synchronous motors were built by replacing the stator winding with a switchable winding and connecting the rotor winding to two pairs of slip-rings located on the opposite sides of the machine. By switching the windings, two different but close in value, numbers of pairs of poles are obtained. Thus, two rotating speeds, differing in values by from 10 to 20 percent are obtained. The calculations based on the examined two dimensional, field-circuit model for the large power motor, type GAe 1510/12p were done. This motor is unique in that its field winding may be connected for 8 or 10 poles. Using the prepared model, calculations of static (load) characteristic were compiled. The following physical quantities were calculated: the magnetic field (normal component of the flux density) of the armature and field winding and the resultant magnetic field and the electromagnetic torque, for both rotating speed and two different configuration of field winding (work with 10 and 8 poles).
