In large cities, due to expensive land price, high-rise buildings are built, in which the space dedicated to the elevators is considerable and reduces the rented surfaces. To decrease these lost surfaces, a Multi Mobile System is proposed: it consists of s ...
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 ...
Based on a mathematical model, simulation results show how the mechanical performances of the motor are sensitive to the prestressing force. A test bench has been developed in the laboratory for experimental measurements. The motor is driven by a two-phase ...
In this article a high performance Extended Kalman filter algorithm is used to estimate rotor speed, rotor position and load torque in a Hybrid Stepper Motor (HSM). Together with a PI speed controller, the Kalman filter forms a very robust sensorless close ...
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 ...
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 ...
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 ...
This paper is related to the characteristics of a traveling wave ultrasonic linear motor. After a brief state of the art of this type of motor, the working principle is presented. Then, to describe analytically the phenomena existing, a theoretical model i ...
To design actuators or motors requires analyzing a lot of parameters such as length, temperature, efficiency, weight, etc. To obtain the optimum results for given specifications the solution is to analyze globally all the free parameters in one go, with an ...
The Industrial Electronics Laboratory at the Swiss Federal Institute of Technology, Lausanne, Switzerland, has built a prototype of a revolutionary two-wheeled vehicle. Due to its configuration with two coaxial wheels, each of which is coupled to a dc moto ...
