| Abstract | ||
| This paper describes the torque and magnetic flux analysis using an advanced dynamic dynamometer test bed for electromechanical motors. Test motor was tested under different levels of continuous loads and high bandwidth complex duty cycle loads in order to provide data to characterize the nonlinear properties of electric motors. The test bed to obtain torque saturation limit data is comprised of a servo motor which serves as a dynamic load emulator, a brake, a clutch, and full sensor array for comprehensive monitoring of test variables, (including magnetic flux density sensor). The magnetic flux test was conducted to discriminate magnetic saturation from torque saturation. Given the permanent magnet motor test system designed for a desired saturation limit, it is possible to predict saturation using a properly defined dynamic duty cycle norm as a function of the operating conditions and the actuator design parameters. In this paper, the temperature effects on the magnetic properties of the permanent magnet material were the principal objectives. | ||
