The 42STH48M05X01 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 0.50 A per phase (2-phase ON), and a holding torque of 490 mNm. The motor has a resistance of 18.5 Ω per phase and an inductance of 52 mH per phase. It operates within an ambient temperature range of -20 to +50 °C with a maximum coil temperature of 130 °C (Class B). The rotor inertia is 85 g·cm², and it supports a max radial force of 28 N at 20 mm from the flange and 10 N axial force. Weight is 360 g, and insulation resistance is 100 Mohms at 500 VDC. The lead wire is AWG24 UL1007.
42STH48 High Precision Hybrid Stepper Motor
42STH48M
The 42STH48-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.
