Abstract
A motor control assembly for an electric motor. The motor control assembly is configured to be coupled to the electric motor, and includes a wireless communication module, an input power connector, and an inverter module. The wireless communication module is configured to receive a wireless signal from a system controller. The input power connector is configured to receive a DC voltage from an external power supply module. The inverter module is coupled to the wireless communication module and the input power connector. The inverter module is configured to convert the DC voltage to an AC voltage to operate the electric motor according to the wireless signal.
Claims20
An electric motor control assembly configured to be coupled to an electric motor, said electric motor control assembly comprising:
- a wireless communication module configured to receive a wireless signal from a system controller;
- an input power connector configured to receive a direct current (DC) voltage from a power supply module external to the electric motor control assembly, wherein the power supply module includes an electromagnetic interference (EMI) choke, a rectifier, and a capacitor;
- and
- an inverter module including said wireless communication module and coupled to said input power connector, said inverter module configured to convert the DC voltage to an alternating current (AC) voltage to operate the electric motor according to the wireless signal.
