Re: AC Servo motors, are they all three phase?

Most AC, BLDC, ECM motors are fed from power of 1ph origin, but as Gerry pointed out, to obtain a smoother, more efficient DC power supply when running the larger versions of motors, 3ph is required or optional.
IOW, The 3ph or BLDC servo power is derived from a DC supply.
