Motor control system for electric motor and method of use
First Claim
1. A motor control system for operating an electric motor, said motor control system comprising:
- a power supply module disposed external to the electric motor and configured to convert an alternating current (AC) voltage at a first level to a direct current (DC) voltage at a second level lower than a DC-equivalent voltage of the AC voltage at the first level; and
a motor control assembly coupled to the electric motor, said motor control assembly comprising;
an input power connector configured to receive the DC voltage at the second level from said power supply module; and
an inverter module coupled to said input power connector, said inverter module configured to convert the DC voltage at the second level to an AC motor voltage to operate the electric motor.

Abstract
A motor control system for operating an electric motor is described. The motor control system includes a power supply module disposed external to the electric motor and configured to convert an alternating current (AC) voltage at a first level to a direct current (DC) voltage at a second level lower than a DC-equivalent voltage of the AC voltage at the first level, and a motor control assembly coupled to the electric motor. The motor control assembly includes an input power connector configured to receive the DC voltage at the second level from the power supply module. The motor control assembly also includes an inverter module coupled to the input power connector. The inverter module is configured to convert the DC voltage at the second level to an AC motor voltage to operate the electric motor.
