The 42STH40M15X01 is a 42 mm diameter, 0.9° step angle hybrid stepper motor with a holding torque of 390 mNm and a rated phase current of 1.50 A (2-phase ON). It features ball bearings, a rotor inertia of 58 g⋅cm², and operates within an ambient temperature range of -20°C to +50°C with a maximum coil temperature of 130°C (Class B). The motor has a detent torque of 12 mNm, maximum radial force of 28 N, and maximum axial force of 10 N. It uses AWG24 UL1007 leadwires and weighs 300 g. Insulation resistance is 100 Mohms at 500 VDC, with a dielectric withstand voltage of 500 VDC for one minute.
42STH40 High Precision Hybrid Stepper Motor
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.
