Abstract
A motor driving circuit including a first and a second driving signal output circuit is configured to selectively output a six-step square wave driving signal from the first driving signal output circuit, or a space-vector driving signal from the second driving signal output circuit to an inverter to drive a motor according to whether an operating power exceeds a power threshold. The first driving signal output circuit is configured to generate the six-step square wave driving signal. The second driving signal output circuit is configured to generate the space-vector driving signal.
