Your cart is empty.This hybrid bipolar stepper motor is the miniature stepper motor we carry, it with 1.8 deg. step angle (200 steps/revolution). Each phase draws 200 mA at 4.8 V, allowing for a holding torque of 1.6Ncm(2.3oz.in). Electrical Specification: * Manufacturer Part Number: 8HS11-0204S * Motor Type: Bipolar Stepper * Step Angle: 1.8 deg. * Holding Torque: 1.6Ncm(2.3oz.in) * Rated Current/phase: 0.2A * Phase Resistance: 24ohms * Inductance: 8mH+/-20%(1KHz) Physical Specification: * Frame Size: 20 x 20mm * Body Length: 28mm * Shaft Diameter: 4mm * Shaft Length: 10mm * D-cut Length: 7mm * Number of Leads: 4 * Lead Length: 300mm * Weight: 60g Connection: Black(A+), Green(A-), Red(B+), Blue(B-) Warning: Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.

I needed a very small stepper motor for a project and these are great. The mount is different to the more standard NEMA 8 mounts so I easily made my own. I created a very accurate 3D model of this motor that I shared on grabcad. Needs four M2 bolts to mount with a depth of 2.5 to 3mm.

These stepper motors are great, they're stong, precise, and feel high quality. If you have a small project, I'd recommend.

This is a really small stepper motor but, as far as I understand, it does *not* have the normal dimensions for a NEMA-8 motor. Most specs I've seen say a NEMA-8 motor should have 16mm bolt spacing and a 15mm pilot circle. This one has 15.4mm bolt spacing and a 16mm pilot circle. Just be sure to double check that it will fit your application.

I bought this directly from Stepper Online. It will not fit with NEMA 8 motor mounts sold by Servo City (a.k.a. Actobotics and Robotzone). As noted by another buyer, the motor has a pilot circle of 16.0 mm and bolt hole spacing of 15.4 mm, which I measured with calipers. In contrast, the motor mount has a diameter of only 15.75 mm for the pilot circle and 16.0 mm bolt hole spacing.

Did the job. Specs were accurate to the degree I needed.
