Abstract
The present disclosure relates to a motor control circuit and related method that includes a transform component configured to receive current values associated with a motor being driven by the motor control circuit, and output polar coordinate values representing a magnitude component and a direction component of a current space vector. The motor control circuit further includes a control component configured to receive the magnitude component and the direction component of the current space vector, and generate motor control signals for driving the motor.

A motor control system, comprising:
- a transform component configured to receive current values associated with a motor being driven by the motor control circuit, and output polar coordinate values representing a magnitude component and a direction component of a current space vector;
- and
- a control component configured to receive the magnitude component and the direction component of the current space vector, and generate motor control signals for driving the motor.
A method of performing motor control, comprising:
- obtaining current values associated with a motor being driven by a control circuit, wherein the current values represent phases of a current space vector;
- and
- transforming the current values to polar coordinate values representing a magnitude component and a direction component of the current space vector;
- and
- using the polar coordinate values in generating control signals for the control circuit in controlling the motor being driven.
