Description:
20mm micro geared stepper motor
VSM20-MG 20mm stepper motor is composed of a miniature stepper motor with an outer diameter of 20mm and a precision metal gearbox. The deceleration ratio can be customized according to the customer's needs.
The deceleration ratio of this image is 1:35, and the torque is 800g.cm at 20RPM.This series of stepper motor deceleration ratio has:1:3 1:7 1:10 1:16 1:17 1:20 1:30 1:35 1:50 1:63 1:70 1:86 1:115 1:150 1:210 1:250 1:360
The basic stepping Angle of the motor is 18 degrees, which is 20 steps per lap. Combined with the deceleration effect of the reduction gearbox, the rotation Angle resolution of the final motor can reach 0.05~6 degrees.
The customer can select the speed reduction ratio according to different torque speed requirements, and at the same time, the appropriate driving frequency of the stepper motor can achieve the determined speed and torque.
