Product Description:
The 103H7126-5590 is designed by Sanyo Denki that belongs from the StepSyn stepping motor series. Its 1.8° step angle enables high-resolution positioning and consistent torque delivery to make it well suited for linear actuators and belt driven industrial machinery. The 103H712 DC stepping motor has an aluminum alloy housing and steel components.
The 103H7126-5590 DC stepper motor features a single cylindrical D-cut shaft design that delivers secure and slip-free mechanical coupling. Its flange dimension of 56 mm fulfills the NEMA 23 standard for use with standard mounting accessories. The 103H712 DC stepper motor shows a rotor inertia level of 0.36 × 10⁻⁴ kg·m² to operate smoothly with minimal vibration. It measures 75.8 mm in total length and has manageable weight load of 0.98 kg for mechanical frameworks. The 103H712 DC stepper motor supports lead wire connection system and possess unipolar wiring arrangement with a winding resistance of 0.9 Ω and inductance 2.2 mH to improve torque generation. It operates effectively from -10°C to +50°C temperature while functioning under moist levels from 20% to 90% RH (non-condensing) in various operational environmental conditions. It is designed to enable uninterruptible and repetitive cycling operations that result in long-lasting performance with low maintenance needs.
The 103H7126-5590 DC stepper motor operates between 24 to 36 VDC input voltage and draws a nominal rated 3 ADC of current for each phase. It supports feedback encoder and has 6-pin female connector. Through its holding torque of 1.6 Nm, it provides excellent position retention that remains stable. The 103H712 DC stepping motor utilizes passive cooling through natural convection and offers IP43 protection against solid objects greater than 1mm and can handle light rain or water splashes.
