The paper deals with use of numerical techniques implemented in ANSYS software package for simulation of synchronous electric machines with permanent magnets. The possibilities and advantages of simultaneous simulation of the electromagnetic processes inside the synchronous machine with permanent magnets and simulation of the electric processes in control circuit of the drive system with help of the software Maxwell 2D and Simplorer are demonstrated. Results of simulation of the synchronous electric motor drive system of the power steering of a passenger car were collected and discussed.
