Brush Less DC Motor for Railway Carriage Fans

A brush less DC motor is a permanent magnet synchronous electric motor which is driven by direct current (DC) electricity and it accomplishes electronically controlled commutation system (commutation is the process of producing rotational torque in the motor by changing phase currents through it at appropriate times) instead of a mechanically commutation system. Brush less DC motor is also referred as trapezoidal permanent magnet motors. Brush less DC motor is an indispensable part of modern drive technology, most commonly employed for actuating drives, machine tools, electric propulsion, robotics, computer peripherals and also for electrical power generation. Brush less DC motor has no mechanical commutator and associated problems. Brush less DC motor is highly efficient due to the use of permanent magnet rotor. High speed of operation even in loaded and unloaded conditions due to the absence of brushes that limits the speed. Brush less DC motor has smaller motor geometry and is lighter in weight than both brushed type DC and induction AC motors. Brushless DC motor has long life as no inspection and maintenance is required for commutator system. Brush less dc motor has higher dynamic response due to low inertia and carrying windings in the stator. It has Less electromagnetic interference. Brush less DC motor works with low noise due to absence of brushes.
