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 ...
NOVELTY - For control mono-phase or multiphase machines in motor or generating mode with or without pulse width modulation. USE - Control of electrical rotating machines. ADVANTAGE - Can be used for control of single phase and three phase machines. DETAILE ...
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 ...
An original electrical AC loss experimental set-up is presented. For loss comparison purpose, Ic and exponent n are measured with a DC magnetic field between 2 and 400 mT applied perpendicularly to the axis of the sample using a specially designed electrom ...
We present a numerical study of the electrostatic wobble motor. Both finite- element calculations and analytical approaches are used to calculate the torque exerted by the electrodes. Both methods give very similar results, validating an analytical approac ...
For the first time we have characterized a micromotor driven by a piezoelectric PZT (PbZrxTi1-xO3) thin film. Sputter and sol-gel techniques have been applied for the deposition of the PZT films onto a silicon stator membrane, which is 20-30 mu m thick and ...
A theoretical analysis of temperature distribution on an artificial ventricular assist device is performed using three-dimensional finite element modelling. The model consists of 6000 solid elements representing all the ventricle components. In order to fi ...
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 ...
This paper presents a simulator of the manufacturing process of induction motors. Its main purpose is to provide feedback in the form of motor cost and production scheduling during the process of motor design. The paper concentrates on modeling and simulat ...
