BLDC motors also offer high durability and low electric noise generation, thanks to the lack of brushes. 0000013091 00000 n [15], Brushless motors are commonly used as pump, fan and spindle drives in adjustable or variable speed applications as they are capable of developing high torque with good speed response. Without brushes, the motors also have very low noise emissions. 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. A brushless motor is an electric motor that uses a permanent magnet rotor and a stator with coils to generate a rotating magnetic field that causes the rotor to spin. 0000008112 00000 n Having the electromagnet in the center of the motor makes it harder to cool. The motor's rotation is managed by a controller that delivers timed bursts of current to the electromagnets in the motor, which in turn controls its speed. This is automatic in a brushed motor due to the fixed geometry of the rotor shaft and brushes. 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. DC servo The simplest type of motor is the brushed DC motor.

When you run electricity into this electromagnet, it creates a magnetic field in the armature that attracts and repels the magnets in the stator. In brushed motors this is done with a rotary switch on the motor's shaft called a commutator. The brushes, as the rotor spins, make contact with the stator, flipping the magnetic field and allowing the rotor to spin a full 360-degrees. 0000014301 00000 n In addition, we have held on to the world's No. Special Offer on Antivirus Software From HowStuffWorks and TotalAV Security. AC motor Today, brushed motors are used only in low power applications or where only DC is available, but the above drawbacks limit their use even in these applications.
