The 57STH76M40X01 is a 57 mm hybrid stepper motor with a 0.9° step angle and a minimum holding torque of 2000 mNm. It features ball bearings, a rated current of 4.00 A per phase (2-phase ON), a phase resistance of 0.6 Ω, and an inductance of 3.5 mH. The motor has a rotor inertia of 460 g·cm², a maximum coil temperature of 130 °C (Class B), and operates within an ambient temperature range of -20 °C to +50 °C. It supports 400 steps per revolution, has a dielectric strength of 500 VDC, and an insulation resistance of 100 MΩ at 500 VDC. The motor weighs 1030 g and uses AWG22 UL1007 leadwires.

57STH76M
The 57STH76-High Precision is a 2 phases 0.9° hybrid stepper motor. This high resolution stepper motor has half the step angle of standard stepper motors. The high precision type increases motor resolution from 200 steps/revolution to 400 steps/revolution. Smaller step angles can be achieved by half-step driving or microstep driving. If the pulse speed is within resonance region, vibration may increase. The stopping accuracy improves as the torque increases while minimizing the negative effect of the frictional load. Resonance regions can be avoided by switching to a 0.9° high-resolution type stepper motor.
