BMC Motor

Electronically commutated motors powered by a direct current electric source through an external motor controller are known as brushless direct current electric motors or brushless DC motors . BLDC motors require an external controller to provide commutation for the process of switching current in the motor phases to produce motion, in contrast to their brushed siblings.  In contrast to BLDC motors, which do not have actual brushes to accomplish this operation twice per spin, brushed motors can have any number of pole pairs for commutation because of the nature of their architecture.   Basics of BLDC Motor Commutation   A 3-phase BLDC motor design is the most typical. While the rotor poles might have any number of pairs depending on the application, the number of phases corresponds to the number of stator windings. To efficiently operate the three motor phases of brushless DC motors, the stator pole position must be tracked because the rotor is affected by the r...

  Eddy-current brakes, commonly referred to as electric ones, are a substitute for conventional hydraulic ones. This device uses an electromagnetic force between an electromagnet and the surrounding conductive material, such as eddy current induced in that for electromagnetic induction, to slow down or stop a moving body by dissipating its kinetic energy as heat and braking force. In today's world, electromagnetic eddy current brake is used in numerous applications.        Types of Electromagnetic Eddy Current Brake   Linear Eddy-Current Brakes Here, the magnet is maintained at a constant distance from the rail rather than touching it.     As opposed to a disc brake, which physically touches each segment of the disc through the brake, this linear brake only goes through its magnetic field, which results in less heat production, less noise, no wear-and-tear, and a higher braking power than traditional disc brakes.    For emergency b...
