Electromagnetic torque calculation of induction motor with ring windings by dint of “ANSYS Maxwell”

摘要

In this article it is considered the electromagnetic torque calculation of low power induction motor with ring windings (IMRW), designed for using in radioactive waste recycling equipment, in environments with high levels of radiation and temperatures over 200 degrees by dint of “ANSYS Maxwell”. The design of the magnetic stator system has not axis of symmetry and provides layered organization of movement of the stator magnetic field: from linear movement in the stator yoke to the circular movement in the rotor. The magnetic rotor system and its windings are performed by the classical scheme. This paper presents the process of calculating the electromagnetic torque in IMRW with squirrel cage for the number of pole pairs p = 1 and the power P = 2.2 kW. Since the motor has a spatial asymmetry, for the construction of the computational model was used 3D modeling mode.
