Abstract
Electrical machines, for example transverse flux machines and/or commutated flux machines, may be “balanced” to achieve reduced overall cogging torque via utilization of one or more cogging torque reduction devices. Cogging torque reduction devices may be configured and/or otherwise customized in order to reduce and/or minimize cogging torque in an electrical machine, by generating a counteracting cogging torque waveform that at least partially counteracts and/or cancels the initial cogging torque waveform of the electrical machine.
