In the process of design, master the design principles of small and medium-sized three-phase induction motor, familiar with relevant technical conditions, based on the given parameters combining with related technical conditions, determine the size of the associated with the electromagnetic performance of the motor, \option, rotor slot number and groove, groove type size ,selected materials programming electromagnetic calculation, Finally, combined with the previous data to calculate the working performance and the corresponding starting performance, including efficiency, power factor, the maximum torque, starting torque, starting current ratio etc. In order to reduce the error and the amount of calculation, prepared electromagnetic calculation program in MATLAB. In addition, the design also drawing, the rotor and the stator , windings distribution prints with CAD. the technical indicators in line with the requirements of specification. To determine the size of the motor performance, as well as to the trough type selection, the selected size, by the repeated debug programming, make the tech
