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 ...
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 ...
A new crane design, labeled "SpiderCrane", is proposed to handle fast load displacements. Its main particularity is the absence of heavy mobile components. The system beeing underactuated, its control is challenging. Hence, as a step towards easier and mor ...
This publication presents the application of Non-Linear Programming (NLP) to the design of AC induction motors driving hydraulic pumps on commercial aircrafts. In addition to the usual constraints on the geometry or on the efficiency of the motor, the spec ...
Hydropower use is responsible for a wide range of environmental disturbances to river systems. Over the past decades, aquatic science research has been successful in identifying a considerable number of relationships that exist between plant operation and ...
In some applications, it is interesting to know the position of a BLDC Motor at standstill. This paper propose one solution using the saturation property of the motor. Principle, simulation and measures are presented. The results of industrial applications ...
The vibration-reduction and sound-absorption properties of a truss-core sandwich beam are analyzed. The core is composed by the assembly of unit cells across both the length and thickness of the proposed beam. The cells have chiral geometry which features ...
We present an exact model for determining the cogging torque in a brushless DC (BLDC) motor. It is based on the conformal mapping (CM) method, by which the motor configuration is transformed to a configuration where the magnetic field can be determined. Th ...
The goal of this semester project is to create a thermal model of a electronic circuit board that will be used to control a Brushless DC motor for the project “Solar Impulse”. For this project, the finite element (FEM) software Ansys is used to build the m ...
Piezoelectric motors (usually called ultrasonic) show interesting characteristics. Not only they deliver high torques at low speeds but their structure confers to them a braking torque without energy supply. This paper firstly present a list of possible so ...
