The 42STH40M10X01 is a 42 mm hybrid stepper motor with a 0.9° step angle and 400 steps per revolution, designed for high-precision positioning. It features a ball bearing, a rated current of 1.00 A per phase (2-phase ON), and a minimum holding torque of 400 mNm. The motor has a rotor inertia of 58 g·cm², a maximum coil temperature of 130 °C (Class B), and a weight of 300 g. It supports a maximum radial force of 28 N at 20 mm from the flange and a maximum axial force of 10 N. The insulation resistance is 100 Mohms at 500 VDC, and it withstands 500 VDC for one minute. Operating temperature ranges from -20 °C to +50 °C. Leadwires are AWG24 UL1007.

42STH40M
The 42STH40-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.
