Air conditioners The current generates magnetic fields in the coils; this causes the coil assembly to rotate, as each coil is pushed away from the like pole and pulled toward the unlike pole of the fixed field. A brushless DC motor (known as BLDC) 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 BROWSE CATALOG. 0000014301 00000 n The Electric Motor.

Intermediate Below, we look briefly at the features and uses of each type. Development of this motor has been made possible due to the evolution of the semiconductor and peripheral device technologies. This system has all sorts of advantages: The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor. Because of all these advantages, brushless DC motors are often used in modern devices where low noise and low heat are required, especially in devices that run continuously. A brushless DC electric motor ( BLDC ), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. 0000008616 00000 n (torque constant) and 0000005290 00000 n %PDF-1.4 % The outside rotor requires appropriate safety measures.
