Brushless DC Motor Common-mode Voltage Analysis

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...

Simulation and Implementation of Current Control of Brushless Dc Motor Based on a Common Dc Signal

The objective of this project is to build a simple current controlled modulation technique for brushless dc motors. In electric traction and most other applications, a wide range of speed and torque control of the electric motor is required. The dc machine fulfills these requirements, but the dc machine requires constant maintenance. But the brushless permanent magnet motors do not have brushes...

Sensorless Drive of Brushless Dc Motor Based upon Wavelet Analysis

This study tackles to develop a sensorless drive technique for brushless dc motors (BLDC) by using wavelet theory. Initially a BLDC motor with hall sensors is handled. The simulink model of the motor is established and the simulation performances are obtained. Then BLDC motor’s PWM pulses are produced by DS2201 dSPACE digital signal processing (DSP) rapid control prototyping kit. The time domai...

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...
