Abstract

Here, the students learn how brushless DC motors have made personal electric vehicles (PEVs) possible, and calculate how much using a PEV instead of an automobile for some of their daily driving can impact their production of carbon dioxide, based on United States driving patterns. In the laboratory, students build a brushless DC motor using three different control methods, based on a reed switch, a Hall effect sensor, and optoelectronics, respectively. In the process, students learn about ....etc

Abstract
This paper presents a control scheme combined with neural network, fuzzy controller and PI- controller for the brushless DC motor. The neural network control learned continuously and gradually becomes the main effective control. Performances of the proposed neural network are compared with the corresponding fuzzy PI controller and conventional PI controller. Matlab/simulink software was used to simulate the proposed scheme. Neural network improves speed response and ....etc

Abstract:
The Brush less DC electric motor are synchronous electric motors powered by direct-current (DC) electricity and having electronic commutation systems, rather than mechanical commutators and brushes. The current-to-torque and voltage-to-speed relationships of BLDC motors are linear.Brushless DC electric motor (BLDC) described as Stepper motors, with fixed permanent magnets and possibly more poles on the stator than the rotor, or Reluctance motors. BLDC is most popular motor choice for model aircraft. because Brush less DC electric mo ....etc

Adaptive Integral Position Control Using RBF Neural Networks for
Brushless DC Linear Motor Drive
Abstract
The paper presents an adaptive integral positioncontroller usingRBF (Radial Basis Function) neural networks (NNs)for a brushless DC linear motor. By assuming that the upper boundsof the nonlinear friction and force ripple, an RBF NN is used forapproximating the friction, the force ripple and the load; an adaptivebackstepping control with integral action is then proposed to achieveposition tracking of the linear motor. The paramete ....etc

BRUSHLESS DC ELECTRIC MOTOR
A microprocessor-controlled BLDC motor powering a micro remote-controlled airplane. This external rotor motor weighs 5 grams, consumes approximately 11 watts (15 millihorsepower) and produces thrust of more than twice the weight of the plane.
Brushless DC motors (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous electric motors powered by direct-current (DC) electricity and having electronic commutation systems, rather than mechanical ....etc
