Design of Motor Characteristic Testbed for Permanent-Magnet Assisted Synchronous Reluctance Motor

In this paper, a motor characteristic testbed used for a permanent-magnet assisted synchronous reluctance motor has been designed and constructed. The main purpose of the testbed is to estimate the motor parameters based on a static testing condition, unlike the motor performance test. This methodology is used to test only the properties of the motor, excluding its inverter. The testbed has been verified with a simulation using a finite-element (FE) method. It can be used to determine a relation between an average torque and a control angle and a torque ripple of the tested motor.
