The SM20 reduction stepper motor has a diameter of 20mm. The length of the motor is 18mm and the length of the reduction box, and the length of the reduction box is 16.0mm, 17.5mm, 19mm and 20.5mm respectively.
The working voltage range of the motor: 2.4V to 12V, the motor speed can achieve the following parameters: 10rpm, 20rpm, 30rpm, 45rpm, 50rpm, 60rpm, 100rpm, 200rpm and 500 rpm.
In the absence of electromagnetic interference and non-overloading, the speed and stop position of the motor are not limited to the frequency of the pulse signal and the number of pulses, and are not affected by the load change.
Mechanical Dimension:MM
Technical Features
The 20mm motor uses ROHS environmentally friendly materials, low energy consumption and low noise. Noise and torque can be customized according to customer needs.
After the stepping motor is equipped with the reduction gearbox, the step angle is further subdivided, so that the load torque is increased and the control is more precise. The gearbox has a variety of different reduction ratios: 10, 12.5, 25, 31.25, 50, 62.5, 78, 100, 125, 156, 195, 250, 315, 390, 488. The rich reduction ratio can meet different precision and Speed demand.
The 20mm geared motor has the characteristics of energy saving, quiet and high efficiency, low energy consumption, low heat, light weight and convenient installation. The mission of the motor is more than 10,000 hours, and the life of the gear is more than 2000 hours.
