This introduction provides a comprehensive overview of the MDD112C-N-020-N2M-180GB2 motor, highlighting its key features, application scenarios, and technical parameters.

DC servo motors are divided into brushed andbrushless motors. Brushed motors are low cost, simple in structure,

have large starting torque, wide speed control range, easy to control, require maintenance, but maintenance is inconvenient

(changing carbon brushes), generate electromagnetic interference, and have environmental requirements. Therefore,

it can be used in ordinary industrial and civil occasions that are sensitive to cost.

Deceleration motor principle

Reduction gear motor, also known as gear reduction motor or reduction motor, is a transmission mechanism that integrates

the motor and the gearbox to drive the closed transmission gear. It is used to reduce the speed and increase the torque to

meet the needs ofmechanical equipment operation.

Application of gear motor: ① Reduce speed.

The motor speed is reduced through the reduction gearbox to achieve the required speed, i.e. the output speed often said. ②Increase torque.

Under the same power condition, the slower the output speed of the gear reduction motor, the greater the torque,

and vice versa. ③ Change the transmission direction.

For example, we can transfer the force vertically to another rotating shaft with two sector gears. ④Clutch function.

We can achieve the purpose of immediate braking by adding a brake clutch.
