A brushless DC motor (BLDC) is an electric motor powered by DC voltage and commutated electronically, rather than by brushes as in a traditional DC motor. The most prominent difference compared to traditional DC motors is the type of commutator. BLDC motors use Hall sensors that are capable of electronically feeding back rotor position information. When paired with an encoder, BLDCs can also be used in applications where precise positioning is required. BLDC can be constructed with the rotor on the inside ("inner rotor") or with the rotor on the outside of the winding ("outer rotor"). The number of windings used in a brushless motor is called the number of phases. Although brushless motors can be constructed with different numbers of phases, three-phase brushless motors are the most common.

By optimizing the design and structure of the three-phase BLDC,RB Motor has been able to provide the motor with superior speed regulation performance, as evidenced by good control performance, wide speed regulation range, good low speed performance, smooth operation, high efficiency, and extremely wide range of applications from industrial to residential.
