Abstract. A mathematical (simulation) model is proposed for brushless direct current motor of telescope turntable. Stator windings of the motor are divided into three independent winding sections. Each winding zone is supplying from own inverter. These sections interact with a general permanent magnet rotor. Influence of stator windings asymmetry on motor static characteristics is studied.
Keywords: brushless DC-motor, divided stator winding, stator coil, elementary torque.
