Permanent magnet DC motor re-design by FEMM

Grmela, P.
Mach, M.
Hajek, V.
This article describes an adjustment of a permanent magnet direct-current motor. This adjustment has been done in order to reduce manufacturing costs due to allowing of machine-made winding. The size of motor has to be unchanged and motor characteristics should be unchanged as well. A finite elements method program has been used for design of the adjusted motor.
