6.*5mm round shaft

Brand name： SEQURE 

ProductWeight:**4.8g

Motor parameters:

Product Name: *7 two-phase stepper motor

Step angle: 1.8 °

Driving voltage: *4V

Rated current: 3A

Rotor inertia: **0g.cm²

Wiring Instructions:

1. VCC : Connect ****0V power supply ( Refer to the working voltage of the motor, general *4V )

2. GND: Ground wire

3. CLK : Control signal (Connected to pulse  )

4. DIR: Direction control signal ( Floating forward, ground reverse )

5. ENA: Connect to enable signal ( Default enable, grounding stops working )

6. P2: Connect one phase to the motor on each side ( Refer to the motor parameter description,   the motor is divided into two phases AB, pins 1 and 2 are connected to one phase, and pins 3 and 4 are connected to the other phase. )

 

DIP switch {ON (1) / OFF (0)}:

1.Div1, Div2 control pulse frequency division

         (1) *0: 4  subdivision

         (2) *0: 8  subdivision

         (3) *1:*6  subdivision

         (4) *1:*2  subdivision

2.Ctl setting control mode, open-loop / closed-loop

          (1) 0 :  Open-loop mode

          (2) 1 :  Closed-loop mode

3.AC setting calibration

   Turn the AC to position 1, and turn on the power. The LED blinks 3 times to start automatic calibration. The motor shaft rotates counterclockwise for one cycle and then clockwise for one cycle. The system automatic calibration complete and the LED continues to flash. The AC dial returns to position 0, and then restart power.

 

Application examples:

1. 3D printing with fine closed-loop positioning
 

• Optical precision aiming (Laser, telescope, camera gimbal, etc.)
• Speed loop record player
• Force feedback / impedance control robot
• Force feedback of game controller
• Adjustable mechanical impedance: virtual spring, damper, etc.
•  Electric transmission device between two axes such as CNC machine tools
• Gravity elimination (eg: offset gravity torque on the robot arm, etc.)
•  Load detection and feature description (Used as a balance, etc.)
