The mechanical encoder increases the cost, the volume and the risk of failure of electrical machines. Therefore, the research on self-sensing control has been enforced within the last years. The concept of short-circuited windings, applied on the rot

Self-sensing control of electrical machines has been a challenging topic in the field of control of electrical machines in the last years. This strategy can be used to omit the encoder, which has positive impact on the cost and the volume of the elec

A resistance- or inductance-based saliency is a requirement for signal injection based self-sensing position estimation methods. A concept of applying short-circuited windings on the rotor of an electrical machine for influencing the differential qua

For sensorless position estimation at low speed and standstill, methods using signal injetion are commonly used. These methods need an electromagnetic saliency as a prerequisite. It can be described by the differential resistance or inductance, deter

Low voltage traction applications demand high torques at low speeds and at a small design space. In order to achieve high torque densities, manufacturers often combine high-speed machines with mechanical gearboxes. In the past decade, flux modulation

Investigations on the Sensorless Position Estimation of an IPMSM with Short-Circuited Rotor Windings
Publikováno v:
2018 IEEE International Magnetics Conference (INTERMAG).
The mechanical encoder of an electrical machine can be omitted in certain cases. Applications, where the requirements are fulfilled, can be realized by using sensorless control. At very low speeds the commonly used methods based on the back-EMF are n

In this paper, a phenomenological 3D hysteresis model using magnetic dipoles, which are mechanically supported on a 3-dimensional grid, is investigated. The different interactions between these dipoles are based on the equations of micromagnetism. In

The phenomenological model, examined in this paper, uses mechanically supported magnetic dipoles, which are arranged to a collective on a regular Cartesian grid. In a former work, the authors showed, that the model is capable to re-enact the basic dy
