PM motor sensorless position detection based on iron B-H local hysteresis

Yves Perriard, Miroslav Markovic, Omar Scaglione

A sensorless position detection technique for a permanent magnet (PM) motor with non-salient rotor is presented. It is shown that the phase self inductances and resistances measured at higher frequencies vary slightly with the rotor position. The origin of ...

An analytical solution for the rotor eddy current losses in a slotless PM motor: the case of current layer excitation

Yves Perriard, Miroslav Markovic, Pierre-Daniel Pfister

We present an analytical solution for the induced eddy currents and the corresponding losses generated in the rotor of a slotless permanent magnet (PM) motor. The field excitation is a current layer placed at the stator interior surface. The solution is ba ...

Power Supply of Long stator Linear Motors – Application to Multi Mobile System

Basile Kawkabani, Yves Perriard, Jean-Jacques Simond

In large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a multi mobile system is proposed. It consists of s ...

Self-Sensing Methods from MEMs to Solar Aircraft Motors

Yves Perriard, Miroslav Markovic, Omar Scaglione

In order to control the speed and/or position of permanent magnet (PM) motors, they require position sensors. Basically, the auto-commutation needs 3 sensors for a 3-phase motor. In micro-motors, as there is no space for the sensors, self-sensing must be u ...
