Description

  • Bipolar stepper motor with planetary gearbox
  • 0.023° step angle and 240 kg·cm of torque
  • Step Accuracy: ± 5 %
  • Comes with the rear shaft exposed

The 12V, 2.8A, 3333 oz-in NEMA-23 Bipolar Stepper Motor has an integrated planetary gearbox with a 76 49/64 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. When connected to a Bipolar HC, the motor has a maximum speed of 25 RPM. At the output of the gearbox, the step angle approximately 0.023°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio. At 2.8 Amps, this stepper motor can produce a maximum torque of 960 kg-cm. However, the gearbox is only rated for 240 kg-cm of continuous torque.

Note: The 2.8V refers to the phase voltage which is different than the 12V rating we give it. At the end of the day, stepper motors don't have a "Rated Voltage" per se. You can run them at a wide range of different voltages and it will just change the performance of the motor. We recommend that you use this motor at a minimum of 12V but you could run it at 24, or 30 if you wanted to and the motor would simply perform a bit better (require less current for a given speed and torque).

Great Motors

Plenty of torque, just make sure you check dimensions twice as they are quite big

Puissant et efficace

Utilisé comme activateur d'une vanne de contrôle de pression (0- 4000 PSI), fonctionne a merveille.

Très puissant

Un autre activateur de vanne de contrôle en association avec le un contrôleur de step motor et un encodeur, toujours aussi efficace

Very Quiet And Powerful

Very good quality, and very low noise. There is some backlash (2 -3 degrees maybe) from the triple planetary gear reduction when the motor is not running, but it runs smoothly. I used a Stafford 1LM012AFXK Flange mount collar to attach it to 40MM aluminum extrusion. It has a 6 bolt 42MM bolt circle, but 4 of the holes (2, 4,8,10 o'clock) will line up with 40MM rail, so you can mount it with T-nuts you just need to drill out the flange holes. It also has the correct keyway, and a split collar with 2 screws to get a good grip on the shaft.

Does the job

Very well constructed with lots of torque!!! Exactly what I was looking for. Takes .8 amps with no load. Highly recommended
