A quick overview on rotatory Brush and Brushless DC Motors



INTRODUCTION
The electric motor in its simplest terms is a converter of electrical energy to useful mechanical energy. It operates on the principle that two magnetic fields within certain prescribed areas react upon each other. One field is produced by a permanent magnet assembly while the other field is produced by an electrical current flowing in the motor windings. These two fields result in a to ....etc

Introduction :
Several different technologies are used in the generator portion of wind turbines (wind generators). One of the older, more reliable technologies is the brushless DC alternator. Basic Theory of Brushless Alternator is nothing but When an electric current is passed through a coil of wire, a magnetic field is produced (an electromagnet). Conversely, when a magnetic field is moved through a coil of wire, a voltage is induced in the wire. The induced voltage becomes a current when the electrons have some place to go such as into a ....etc

A Brushless Servomotor has been developed by using interdisciplinary mechatronics engineering. A mechanical switching device (commutator) is replaced by electronic circuits and controllers resulting in maintenance free and high performance servo drive. The brushless servomotor is an ac motor, in all respects and is in fact called the ac servomotor. Combined with a dedicated control device, the performance of the brushless servomotor is found to be equal to the performance of the high performance dc servo motor. In dc motor when the current fl ....etc

INTRODUCTION

Brushless Direct Current (BLDC) motors are one of the motor types rapidly gaining popularity. BLDC motors are used in industries such as Appliances, Automotive, Aerospace, Consumer, Medical, Industrial Automation Equipment and Instrumentation. As the name implies, BLDC motors do not use brushes for commutation; instead, they are electronically commutated.
BLDC motors have many advantages over
brushed DC motors and induction motors. A few of
these are:
• Better speed versus torque c ....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
