Brush motor magnetic circuit is constructed with three-dimensional. Due to time constraint, difficulty occurs to simulate all factors by three-dimensional model. Reduction of necessary simulation time depends on how to implement three-dimensional model simulation on two-dimensional. This presentation describes proper use of three and two dimensional simulation, and JMAG adapting method for brush motor magnetic simulation.
