This paper presents the computer-aided design and performance analysis of the universal motor for vacuum cleaning machine. The design optimization of the motor geometry was achieved with the computer-aided design and analysis of finite-element electromagnetic field. Simulation study on the transient performance of the motor was carried out to ensure the motor runs efficiently in the entire permitted speed and load range. Time stepping integration method and 2D finite element field solutions are used for solving the system. An arcing model is introduced into the system to predict brush switched commutation and the torque ripples. Performances of a designed motor are verified with simulation results.
