Sensorless control of PMSM's (Permanent Magnet Synchronous Motors) has occupied scientists for a long time. The result of this research is becoming widely accepted by the industry due to its low cost and reliability. However, the majority of today's motor ...
The aim of this project is the design and the optimization of the electrical motors used in the Continuously Variable Transmission (CVT) system currently under development at JTEKT, an automotive part supplier company. Two motors are needed for the control ...
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 ...
The paper presents a method to determine hysteresis losses in synchronous permanent magnet (PM) motors. The method comprises four steps: (1) experimental determination of the B-H loop, (2) analytical modeling of the B-H loop by applying different models, ( ...
Extended Kalman filtering techniques have been successfully used as sensorless control schemes on many different types of synchronous motors. One big disadvantage of the extended Kalman filtering technique is the large computational cost. Even with today's ...
Electric motors consume over half of the electrical energy produced by power stations, almost the three-quarters of the electrical consumption in industry and almost the half of commercial electrical consumption in developed countries. Motors are by far th ...
In many applications, industry has tried to develop sinusoidal supply for brushless DC (BLDC) motors. This paper describes a method that still keeps a simple 2 phases-on sensorless method and achieves sinusoidal supply, which is needed to avoid speed oscil ...
The present paper deals with the determination of voltage stresses on PWM inverter fed induction motors by considering first the cable modeling and the measurement of different parameters. Then, based on this model, voltage stresses on the motor windings a ...
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 ...
Designing actuators or motors requires analysis of a lot of parameters such as length, temperature, efficiency, and weight. A global analysis to evaluate these parameters is possible. Three methods can be used: 1) an analytical method, allowing parametric ...
