Working Principle and Operation of BLDC Motor. BLDC motor works on the principle similar to that of a conventional DC motor, i.e., the Lorentz force law which states that whenever a current carrying conductor placed in a magnetic field it experiences a force. As a consequence of reaction force, the magnet will experience an equal and opposite ...

How They Work Mechanically. Kiln thrust rollers function by counteracting the gravitational force acting on the kiln. As the kiln is tilted at a slight angle, gravity tries to pull it downwards along this incline. The thrust roller, mounted at the downhill end of the kiln, prevents this downward motion by "pushing back" or exerting an equal ...
