Transverse and/or commutated flux systems having phase offset |
摘要 |
Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve reduced overall cogging torque via implementation of a sixth-phase offset. Individual cogging torque waveforms in the electrical machine may be evenly distributed across one-sixth of a voltage phase or other suitable spacing, resulting in a reduced magnitude and/or increased sinusoidality of the overall cogging torque waveform for the electrical machine.
