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 ...
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 ...
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 ...
