15BY Mini 15mm 2-Phase 4-Wire Stepper Motor Stepping Motor Linear Screw Shaft Rod Block 13 Teeth Plastic Gear DIY Camera Monitor _x000D_ _x000D_ _x000D_ _x000D_ Specification: _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ new miniature 15mm two-phase four wire stepper motor. Its output shaft is a worm gear, _x000D_ which drives the gears to rotate and forms a worm gear reduction transmission relationship, _x000D_ with a reduction ratio of 1:9.5. _x000D_ _x000D_ The stepping angle of the motor itself is 18 degrees, which is two pulses to rotate 360 degrees. Now, after deceleration, the gear needs 190 pulse signals to rotate 360 degrees. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ We have not yet figured out the specific usage method of this small deceleration component. _x000D_ Buyers should feel that it can be used before placing an order. We cannot provide technical support, please understand. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Note: This motor is a two-phase four wire stepper motor, which requires an external stepper driver and pulse signal to operate normally. It cannot work if directly connected to a DC power supply. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1.Motor lead length: 60mm _x000D_ _x000D_ 2.Weight: 15g _x000D_ _x000D_ 3.Motor type: 2-phase 4-wire stepper motor _x000D_ _x000D_ 4.Motor phase resistance: about 9.6 ohms _x000D_ _x000D_ 5.@5V short circuit current: 0.49A _x000D_ _x000D_ 6.Gear rario: 1:9.5 _x000D_ _x000D_ 7.Tips: The working mode of this stepper motor is driven by the driver to rotate the gear. _x000D_ The outer diameter of the gear is 7.6 mm, with 13 teeth and a gear module of 0.5 module. _x000D_ It requires 190 pulse signals and the plastic gear rotates 360 degrees. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ ========================= _x000D_ _x000D_ _x000D_ _x000D_ Package List: _x000D_ _x000D_ _x000D_ _x000D_ Stepper Motor x 1PCS _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
