Abstract
A stator of the planar magnetized rotor motor according to the invention comprises groups of polar parts and at least two control coils. On each side of the rotor, each group of polar parts surrounded by a coil is arranged adjacent to the groups which are not surrounded by a coil. This arrangement makes it possible to increase the number of active poles of the stator, thereby increasing the motor torque, in a small size, economical, simple construction motor.
