The main difference between servo motor and stepper motor with planetary reducer is that the motor is controlled by servo with high precision. With the increase of torque, the speed decreases at a constant speed. The precision of the stepper motor system is slightly lower. The output torque decreases with the increase of speed. The step motor is used at low speed (N times lower cost), and the servo motor is used at high speed (high cost)

The planetary reducer is characterized by economy, practicality, high cost performance, high precision, good rigidity, large bearing management capacity, high efficiency, long service life, small size, beautiful appearance design, convenient installation and use, and more accurate positioning. It is applicable to the speed increase and deceleration transmission of AC servo motor, DC servo motor, stepping motor and hydraulic motor.

Precision planetary reducer: square flange design, convenient installation size. Models include: 40, 60, 90, 120, 160, 200 and other common base models. There are more than 20 speed ratios from 4 to 1000, including one reduction drive, two reduction drives and three reduction drives. Its accuracy: the first level transmission accuracy is 5-10 minutes of arc, and the second level transmission accuracy is 7-12 minutes of arc; The three-stage transmission accuracy is 9-15 minutes of arc; Hundreds of specifications.

Application: The planetary reducer can be directly installed on the AC/DC servo motor, and is widely used in the industrial field with medium accuracy. For example, precision machine tools, welding equipment, automatic cutting equipment, packaging equipment, solar energy, industrial robots, printing equipment, precision testing equipment and other equipment used in automatic CNC machine tools.

Performance and characteristics: The planetary reducer has the advantages of high performance price ratio, wide application range, economy, long service life, etc. It has good servo rigidity effect and accurate positioning control. The operating platform has the characteristics of medium and low rear clearance, high efficiency, high input speed, high input torque, stable operation, low noise, light and compact shape and structure design. No matter where the lubricating oil is installed, it can be used in a totally enclosed design for maintenance free operation, so it can also be used in harsh working environments.
