Abstract

This article mainly about electromagnetic design and calculation of motor. First it determined the main dimensions related to the electromagnetic properties of the Y2-160M1-2 motor based on the parameters of dsign task and technical conditions. Then it selected the number of slots of stator and rotor and right slots. I not only used to draw size chart of stator, rotor and coil but also draw distribution of groove and winding. I calculated some basic amount such as the number of conductors in series per phase and slot fill factor. Then I selected the related materials. I have completed the electromagnetic calculations of this motor . Then I adjusted the parameters repeatedly. I did a lot of work to make its technical indicators meet the requirements of the mission statement. In the last I designed the motor that meet the requirements of the mission statement.
