What Is 775 Gear Motor

A 775 gear motor is a unique type of DC motor, composed of two main parts: the 775 DC motor and a gear reducer. What sets it apart is the fusion of its dual characteristics of high speed and high torque output, allowing it to exhibit outstanding performance in various fields.

775 DC Motor

The motor core of the 775 gear motor, which serves as its primary driving unit, utilizes DC motor technology. This motor design is intended to provide the capability of high-speed operation to meet the requirements of applications demanding higher speeds. High speed DC motors typically demonstrate elevated rotational speeds, thus offering swift motion and response in certain tasks.

Planetary Gearbox

Another crucial component of the 775 gear motor is the gearbox, which includes a planetary gear system. At INEED Electronics, we commonly integrate a planetary gearbox with the 775 motor. If desired, spur gearbox can also be provided. The gearbox contains multiple gears that function to decrease the rotational speed of the motor’s output shaft while simultaneously increasing the output torque. This means that even during high-speed operation of the motor, the gearbox is capable of reducing the output speed while delivering greater torque. This design caters to applications requiring high torque but at lower speeds.
