Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze, Vincent Reymond

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...

Optimization of a new type of ultrasonic linear motor

Yves Perriard, José Fernandez Lopez

This paper presents the design, the properties, and the optimization study of a new type of ultrasonic linear motor. Numerical modeling has been carried out and simulations with software have been realized. To avoid performing a large number of simulations ...

Self-sensing methods to drive micro-machines

Yves Perriard, Omar Scaglione, Jan Persson

Synchronous motors require sensors in order to control these devices in speed and/or position. Basically, the auto-commutation needs 3 sensors for a 3-phase type actuator. In micro-motors, as there is no more room to place the sensors, self-sensing approac ...

Optimization of a Single Phase Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez, Markus Flückiger

Piezoelectric ultrasonic motors are superior to electromagnetic micromotors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potenti ...

Comparative study and selection criteria of linear motors

Samuel Chevailler

Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...

Simplified Design Methodology for a Slotless Brushless DC Motor

Yves Perriard, Miroslav Markovic

The paper presents a simplified analytical method to design a small two-pole slotless brushless dc motor. Using only a few approximations, the motor analytical model is formulated to generate a system of equations. The system can be solved analytically, pr ...
