Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Multiphase variable-speed drives are typically supplied from a two-level voltage source inverter (VSI). The number of phases of the machine and hence the legs of the inverter can be either a prime or a composite number. Limits of the dc bus utilisation in ...
AC introduction motors have been used in traction applications for a long time. They have a good efficiency for a low cost and are very robust. Most of these motors have been developed for industrial applications and they have a torque ripple because of th ...
Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...
This paper presents a linear direct-quadrature (dq) current control strategy for voltage source converters (VSCs) in a rotating reference frame (RRF). The described method is based on Multivariable proportional-integral (PI) regulators and provides fast dy ...

Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
Multiphase series-connected motor drives can be supplied from a two-level voltage source inverter (VSI), which has either a prime or a composite number of legs (phases). It has been shown recently that, in the case of a prime number of inverter/machine pha ...
This dissertation considers mechatronic systems driven by piezoelectric ultrasonic motors (PUM). The focus is set on optimal system design and sensorless position control. Mechatronic industry faces the challenge to deliver ever more efficient and reliable ...
This paper presents preliminary results in the frame of the development of a very high speed synchronous drive with a rated power of 6 kW at the rated speed of 180 krpm taking place in the context of a university-industry partnership. Due to the very high ...
This paper presents the start-up and synchronization procedures of large variable- speed pump-turbine units in pumping mode. These procedures applied to a doubly-fed induction motor-generator with three-level voltage source inverters VSI cascade in the rot ...
Nowadays, more and more electrical motors are being used in mobile applications, such as hybrid cars for the automotive sector or even in aeronautics applications. A typical example is the solar impulse airplane which is propelled with four electrical moto ...
