Design and optimization of dc brushless permanent magnet motor
Electric motors that have found wide application in various sectors of industry Have unique features such as high reliability, high efficiency, quick acceleration and have small sizes. Brushless DC motors meet these requirements well. In this study, the design of a brushless DC motor speed limits for the particular application at 1800 rpm that can be equivalent to 140 watts output was provided....
متن کاملSensorless Permanent Magnet Drive Design
The development procedure of permanent magnet drives for sensor less operation beginning from standstill under overload conditions has to consider different design aspects coevally. First, the robust rotor position sensing by test signal enforces a design with a strongly different behavior of the spatial dq-oriented differential inductance values. Therefore, the interior rotor magnet array arra...
متن کاملPermanent Magnet Linear Generator Design
The purpose of this design is to improve the efficiency of power extraction from sea waves. Sea waves are huge untapped energy resources. There are many methods to generate electricity from power of sea waves. But, all these conventional methods use mechanics, which have a lesser efficiency than electrical systems. A new design of permanent magnet linear generator is proposed which moves with t...
متن کاملThe Design of Eddy-current Magnet Brakes
The eddy-current is created by the relative motion between a magnet and a metal (or alloy) conductor. The current induces the reverse magnetic field and results in the deceleration of motion. The proposed mechanism implements this phenomenon in developing a braking system. The potential applications of the braking system can be a decelerating system to increase the safety of an elevator or any ...
متن کاملDesign of Permanent Magnet Hysteresis Motors
The hysteresis motor is so named because it is producing mechanical torque utilizing the phenomenon of hysteresis. The rotor of a hysteresis motor is a cylindrical tube of high hysteresis loss permanent magnet material without windings or slots. This paper presents the design of a hysteresis permanent magnet motor using the finite element method. The rotor of the machine consists of 36% Cobalt ...
