Multiwinding motor specifications
Common-mode current is applied to the
common-mode windings.
This drives a motor with capacity of the summed
number of inverters.
For example, by using four (n = 4) 200 kW
inverters to drive a four-winding motor, up to
800 kW output is available.
The relationship between the number of windings and the number of motor poles is as listed below
because the former should be a divisor of the latter.
