About products and suppliers

A brushless DC electric motor is basically a motor that is turned inside out, which gets rid of the need for brushes to flip the electromagnetic field. In brushless electric motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. BLDC (brushless DC) motors can have from 85 to 90 percent efficiency, which is higher than the standard brushed motors which have 75 to 80 percent efficiency. For many applications involving a DC or BLDC motor, it is advisable to use a brushless DC motor controller. If you are using a brushless (electrically commutated “EC”) motor, then you've got to use a controller to fire the right phase winding at the correct time.

Are Brushless DC Motors Better?

Brushless DC motors are low maintenance and non-sparking because they don't have a mechanical commutator or brushes that can wear out. Additionally, they produce less shaft friction and inertia, less audible noise, and far better torque-to-weight ratios (power density). A high torque brushless motor is far smaller in size than a comparable brush DC motor. A brushless DC fan uses brushless DC motors (BLDC motor) that have a cross-pattern arrangement of 4 permanent magnets mounted on the edges of the rotor. A brushless gear motor requires little or no maintenance, provides long life, and quiet operation. There are many types of motors to choose from including 12v brushless motors, 48v brushless motors, and many more depending on your needs.

Are AC Motors Brushless?

All AC induction motors are brushless. In a small brushless motor, fewer moving parts mean less friction and heat, and this reduces wear on the components of the motor. The absence of brushes, commutators, and slip rings also makes them much cheaper than other types of motors. A brushless AC motor also has a lower start-up power.
