Simulation and measurement of synchronous motor prototype with an external rotor by using permanent magnets

This paper presents the design, simulation and measurement of a synchronous motor prototype with an external rotor by using permanent magnets which was optimized for high-torque, in-wheel operation. Based on geometric dimensions, the 3D solid model was created in ANSYS/Maxwell program. The electromagnetic design was calculated in ANSYS/RMxprt program. The cross section with graphical presentation of magnetic induction in particular parts of electromagnetic circuits and the simulated and measured characteristics of the motor are shown.
