Control of an Electric Machine Integrated with the Trans-Rotary Magnetic Gear in a Motor Drive Train Conference Paper uri icon

abstract

  • © 2015 IEEE. This paper studies the dynamic performance of an electric machine integrated with the trans-rotary magnetic gear (MITROMAG) in a motoring mode of operation. MITROMAG is formed by mechanically coupling a rotary electric machine to the rotor of a trans-rotary magnetic gear (TROMAG). TROMAG is a magnetic device that converts low-torque, high-speed rotation of its rotor to a high-force, low-speed linear motion of its translator, and vice versa, through magnetic field. In a motoring mode of operation, the rotor of the TROMAG is driven by a rotary electric motor, and as a result, its translator drives a reciprocating load. A nonlinear dynamic model is developed for the TROMAG. Oscillation tests are presented as examples of how the model can be used to predict the dynamic behavior. The model is then linearized to develop system transfer functions and study the dynamic response of the MITROMAG to speed commands. Experimental results confirm the analysis.
