Efficiency Comparison between Brushless DC Motor and Brushless AC Motor Considering Driving Method and Machine Design

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....

Study on High-Efficiency Brushless DC Motor for Compressor

In Japan, room air conditioners, mainly heat-pump type, have been widely introduced into households. And "one unit to one room" really features today rather than "one unit to one home" in the past. In the circumstances where room-by-room air conditioning or all-season air conditioning systems are increasing, reduction of electric power consumption strongly required. As a consequence, the effici...

Constant 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...

Chaotic 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...
