With a precise 1.8° step angle and 200 steps per revolution, it delivers smooth, accurate motion ideal for DIY robotics, CNC, and 3D printing applications. Rated at 0.6A and 10Ω resistance, this 4-wire motor requires a constant current or chopper drive controller for optimal performance and durability. ## Description This is the highest torque for Nema 8 stepper motor with 1.8 deg. step angle (200 steps/revolution). Each phase draws 600mA, allowing for a holding torque of 4Ncm(5.7oz.in). Electrical Specification: * Manufacturer Part Number: 8HS15-0604S * Motor Type: Bipolar Stepper * Step Angle: 1.8 deg. * Holding Torque: 4Ncm(5.7oz.in) * Rated Current/phase: 0.6A * Phase Resistance: 10ohms * Inductance: 5.5mH+/-20%(1KHz) Physical Specification: * Frame Size: 20 x 20mm * Body Length: 38mm * Shaft Shape: * D-cut * Shaft Diameter: 4mm * Shaft Length: 10mm * D-cut Length: 7mm * Number of Leads: 4 * Lead Length: 300mm * Weight: 80g 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. Review: Powerful for Small NEMA 8 Size - Using the stepper for the Z axis on an ANT PCB cnc machine. The motor came with a great spec sheet. The only thing that would make it more ideal would be a longer shaft than 8.5mm. I used a friction fit instead of a set screw for my coupler.
