Influence of Magnetic Field Character on the Tape Winding Motor Torque Dependance

The paper considers the development of methods for calculating motors with tape winding. Novel motor type allows to obtain an increased torque due to the high current flowing through the tape winding. The numerical studies of the uniform and non-uniform magnetic flux density distributions in the air gap of tape winding motor are provided. It is shown that taking into account the real non-uniform character of magnetic flux density distribution, the torque pulsations during the rotor rotations decrease. Also the ways of the torque pulsations magnitude reducing by changing the geometry of both the magnetic pole and the tape winding plate are indicated.
