BCPM is an entire Brush Commutated DC design environment. The designer can choose from a large library of parameterized geometries or draw from scratch. Once the geometry is complete, windings are added by completing a simple table corresponding to the machine’s real-world windings. The simulator can accommodate permanent magnet as well as series or parallel wound field designs.

The designer then builds the inverter topology and describes the control signals, all with BCPM's built-in schematic capture module. The design is then "run" using one of the solver methods together with finite element magnetic field calculations at successive rotor positions.

Full parameterized output is provided without any additional post-processing. Output ranges from machine inductances, currents, voltages, and torque to flux density and demagnetization plots.

BCPM is easy to learn and use and is easy to remain proficient at, a benefit for casual users, all without sacrificing the in-depth analysis demanded by power users.
