A Brushless DC Electric Motor (BLDC) is an electric motor powered by a direct current voltage supply and commutated electronically instead of by brushes like in conventional DC motors. A BLDC motor is a synchronous, electronically commutated motor that has a stator winding fitted with electromagnets and a series of magnets attached to the motor rotor. Brushless dc motors offer longevity and low maintenance since there are no brushes within the internal construction.
A gear motor is an all-in-one combination of a motor and gearbox. The addition of a gearbox to a motor reduces the speed while increasing the torque output. The most important parameters in regard to gear motors are speed (rpm), torque (lb-in) and efficiency (%). A planetary gearbox is a gearbox with the input shaft and the output shaft aligned. A planetary gearbox is used to transfer the largest torque in the most compact form (known as torque density). There are three classifications of the BLDC motor: single-phase, two-phase and three-phase. This discussion assumes that the stator for each type has the same number of windings. The single-phase and three-phase motors are the most widely used.
A brushless DC motor (BLDC) is basically a synchronous DC motor powered by direct current (DC) and consists of two main parts: a stator and a rotor. Broadly, there are two types of BLDC motors based on the physical design—inner rotor design and outer rotor design. Because computers control the electrical current, brushless DC motors can achieve much more precise motion control. 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.
