The 57STH45M10X01 is a 57 mm hybrid stepper motor with a 0.9° step angle and a minimum holding torque of 700 mNm. It features a ball bearing, 400 steps per revolution, and operates within an ambient temperature range of -20 to +50 °C. The motor has a rated current of 1.00 A per phase (2-phase ON) and a phase resistance of 5.5 Ω. Rotor inertia is 180 g·cm², and it weighs 520 g. The insulation resistance is 100 Mohms at 500 VDC, with a dielectric strength of 500 VDC for one minute. Maximum radial force is 75 N at 20 mm from the flange, and maximum axial force is 15 N. The motor uses AWG22 UL1007 leadwires and has a maximum coil temperature of 130 °C (Class B).
57STH45 High Precision Hybrid Stepper Motor
57STH45M
The 57STH45-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.
