Sensor-less control of linear induction motor considering its asymmetric parameters

When we achiev a good performance of the field-oriented vector control system, it is necessary to detect the speed and flux of the motor. Usually it is hard to implemment these sensors. Then the sensor-less contro-system techniques using the observer inste ...

CMOS compatible fully integrated Mach-Zehnder interferometer in SOI technology

Mihai Adrian Ionescu, Philippe Renaud, Michel Declercq, Philippe Robert, Philippe Flückiger

We present a fully integrated Mach-Zehnder interferometer in silicon-on- insulator technology. Modulation of the index of refraction is achieved through the plasma dispersion effect resulting in a bandwidth in the 10 MHz range. A particular and innovative ...

Analyse et conception de moteurs synchrones chemisés à commutation électronique

The number of brushless DC (BLDC) motor applications has increased significantly, essentially due to reduced costs of semiconductors and permanent magnets, but also because of the emergence of new control strategies, such as closed-loop and sensorless cont ...

Torque control of the three-phase direct reluctance motor

Michel Girardin

This paper describes an open-loop torque control for a three-phase direct reluctance motor which can generate high torque at low speed. The command strategy presente in this paper consists of feeding the motor with three-phase sinewave currents. The torque ...

Voltage peaks of low voltage induction motors due to PWM inverter supply

Jean-Jacques Simond, Basile Kawkabani

In industrial variable speed drives, the supply of low voltage induction motors by IGBT-PWM inverters through screened cables may cause dangerous over-voltage surges at the motors terminals. These voltage peaks of about twice the de link voltage, with a sh ...

Analysis and design of a doubly-salient permanent-magnet small motor with electronic commutation

Yves Perriard, Marcel Jufer

The paper presents a new type of electronically-switched doubly-salient permanent-magnet (DSPM) small motor for household appliances. Its basic structure is similar to that of a switched reluctance motor, except for the presence of high-energy PMs inside t ...
