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 ...
Usually, each phase of the direct reluctance motor is fed separately by its own inverter producing a squarewave phase current depending on the rotor position. In the present work, a star-connection of the three stator phases is used and the direct reluctan ...
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 ...
Precise positioning over a long stroke is required in various fields. Important advances in the field of electromagnetic motors, piezoelectric actuators and bearing technology allow nanometric and sub-arc-second resolution for linear or rotary actuators, r ...
This paper describes a linear motor optimization based on an analytical model. The studied motor, also called "ironless", consists of an iron core U shape with permanent magnets on each side, between which the coils can move. The glider which supports the ...

High-speed bearings and electrical motors are gradually getting available. This is of particular interest for the application of thermal turbomachinery. The availability of high speed bearing and motor components opens the way to new applications for low p ...
The paper describes a modeling tool for the design of a new air-cored current transformer called PRiME (planar Rogowski current measurement) designed on a printed-circuit board (PCB) with the coil made of the PCB printed copper layers. The PRiME technology ...
In this paper, a method for sensorless position estimation of linear transducers at standstill is suggested. The method makes use of current pulses, which is a common sensorless starting technique for 3-phase synchronous motors. Most transducers possess ho ...
NOVELTY - After disconnection from normal control (3) a pulse generator (4) sends positive and negative pulses to a motor winding R. The response currents are measured (5) from voltages (Vpr,Vnr) which appear after a fixed time on a neutral resistor (2) an ...
This paper presents a combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar currents due to t ...
