15mm Dual Motor High Torque GM12-15by Stepper Gear Motor Small Volume With Mini Horizontal Metal Gear Box
15mm stepper motor attached with 1812 worm gearbox
This is a 15mm dual motor, with worm 1812 metal gear box motor
The overall size of the right-angle gearbox motor is small, and the angle between the output shaft and the motor bearing is 90 degrees, which is suitable for the installation requirements of special occasions.
The basic step angle of the motor is 18 degrees, that is, 20 steps per revolution. When matched with the gear box, the final motor angle resolution can reach 0.018~0.9 degrees, which can be used in various places that require precise control.
The selectable speed ratio of this motor metal gear reducer is 1:21 1:42 1:118 1:236 1:302 1:399 1:515 1:603 1:798 1:1030, different speed ratios will produce Different final torque and speed, customers can choose according to different torque and speed requirements. Special speed ratios can be customized, if necessary, please contact us to discuss.
When selecting a motor, it is necessary to comprehensively consider the speed and torque while meeting the requirements. The drive frequency of the stepper motor determines the speed of the motor, and the reduction ratio of the gearbox determines the final output shaft speed. This is a simple formula to help customers choose a motor.
Motor output shaft speed N(rpm)=(PPS*18/6/i). For example, a gearbox with a speed ratio of 118 is selected, the motor is driven at 800pps, and the final output shaft speed is N=800*18/6/118=20.33
For the connection line of the motor, it can be customized according to customer needs
Due to the use of the worm gear structure, the entire motor has a compact structure, but the efficiency of this structure is relatively low, so special attention should be paid when selecting it.
