Magnetic Design of an Electric Motor

Although a motor always has some coils in it the arrangement of these coils can vary widely. We will analyse what arrangement looks the most promising to achieve our goals of full scalability, high efficiency and reasonable price.

Since we aim for a permanent magnet synchronous motor the rotor will always have magnets. But here, too different magnet materials exist and have to be analysed in detail.

The first motor design to be analyzed will be the inrunner motor. For an inrunner we identified the following variables that define the whole motor:
