The 42STH48M15X01 is a 42 mm diameter, 0.9° step angle hybrid stepper motor designed for high-precision positioning. It features a ball bearing, 470 mNm holding torque, and a rated current of 1.50 A per phase with two phases energized. The motor has a rotor inertia of 85 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 delivers 400 steps per revolution and supports a maximum radial force of 28 N at 20 mm from the flange and 10 N axial force. The insulation resistance is 100 Mohms at 500 VDC, and the dielectric strength is 500 VDC for one minute. The motor weighs 360 g and uses AWG24 UL1007 leadwires.

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.
