| Abstract |
This paper presents numerical torque simulations and sensorless control of a permanent magnet synchronous machine (PMSM). The machine was developed for a wheel-hub traction drive with a maximumtorque of 4000 Nm. The Indirect Flux detection by Online Reactance Measurement (INFORM) methodprovides control at standstill and low speed without a rotor position sensor. A back electromotive force(EMF) model handles the operation at higher speed. The structure of the control and the load behaviourof INFORM are shown. The torque characteristic is calculated by numerical simulation and comparedwith recorded values. An additional curve depicts the influence of the INFORM test signals on machinetorque. |
