MOTOR SYSTEM CONTROL

This abstract first appeared for US patent application 20240408974 titled 'MOTOR SYSTEM CONTROL

Original Abstract Submitted

a motor system includes a rechargeable energy storage system, an alternating current motor, and a power inverter. multiple efficiency maps may be provided, each representing a specific combination of control parameters and associated settings. the maps relate the motor's operating space (torque and speed) to corresponding efficiency solutions. the combination of control parameters and settings that yields the highest motor system efficiency at an operating point may be determined from the multiple efficiency maps and used in controlling the motor.
