Zusammenfassung:	A motor controller having low standby power consumption is provided. The motor controller includes a direct current (DC) bus. The motor controller also includes a low-power supply. The motor controller also includes an inverter configured to control a supply of current to stator windings of a motor. The motor controller also includes a switch circuit coupled between the DC bus and the low-power supply. The motor controller also includes a switch controller coupled to the switch circuit and configured to be coupled to a system controller. The switch controller is configured to control the switch circuit to electrically decouple, in response to detecting an absence of a control signal from the system controller, the DC bus from the low-power supply.
