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 کاملConstant Current Models of Brushless DC Motor
Two constant current models of Permanent Magnet Brushless Direct Current Motor (PM BLDC) are presented in the paper. In the first part of the paper principle of operation, basic properties and mathematical equations describing PM BLDC models are given. Then, two different constant current models of PM BLDC motor are considered: In the first model, PM BLDC motor is approximated with dc motor; in...
متن کاملChaotic Dynamic Analysis of Brushless DC Motor
Brushless DC Motor (BLDCM) has high reliability, long service life, which, however, is a typical multivariable, strong coupled complicated nonlinear system. There peacefully coexist complex dynamical behaviors, such as limit cycles and chaotic attractors, coexists peacefully. Therefore, this paper proposes the BLDCM system, to explore these dynamics, we compute and simulate the bifurcation diag...
متن کاملImplementation of a Brushless Dc Motor as a Virtual Motor
Due to their simple structure, high efficiency, fast dynamic response, Permanent Magnet Brushless DC (PMBLDC) machines are extensively used in automation, consumer electronics, electric vehicles and medical and industrial applications. Availability of these high energy density permanent magnet materials enhances the performance of PMBLDC motor drive and also reduces the size and losses in these...
متن کاملSensorless Control of a Brushless DC Motor
This paper uses a new position sensor less drive for brushless DC (BLDC) motors. In conventional sensor less control methods such as the back-EMF detection method, the performance is high only at a high speed range due to the fact that the magnitude of the back-EMF is dependent on the rotor speed. A solution is derived that estimates the rotor position by using an unknown input observer over a ...
