NEMA 11 Specifications

Our NEMA 11 kits come with Bipolar, 1.8 degree step angle (200 steps/revolution), 28x45mm motor with a 5mm shaft.  Each phase draws 670 mA at 4.5 V, delivering 13oz-in of holding torque.  With our 16 tooth GT2 motor pulley, the actuator has a linear holding torque of just over 4lbs.

Recirculating Linear Bearing comes pre-loaded on the actuator rail

 

To get the most out of our actuators you will need these other components:

  • Stepper Motor Driver board
  • Arduino Controller board
  • Program or Sketch for the controller board to send step pulses to the driver board

Knowledge of programming an Arduino or similar microcontroller system will help you customize the acceleration and speed of your actuator, and how far along the rail you want the linear bearing to travel.
