103H7852-7021

The 103H7852-7021 from Sanyo Denki and part of the StepSyn Stepping Motors series is engineered to deliver precision performance in industrial applications. Designed to operate on a DC24V ± 10% source voltage, this stepping motor offers a reliable pull-out torque of 0.98 Nm while supporting a maximum input frequency of 400 kpulses/s. Its primary function is to provide accurate step control and smooth rotational movements for systems that require meticulous positioning and repeatability in operations.

This motor features detailed technical attributes that enhance its performance in automated environments. With an operating current of 0.75A/phase, it is optimized for energy efficiency while ensuring strong operational capability. The motor offers selectable step angle settings, accommodating up to a maximum of 80 divisions to suit various control requirements. Its lightweight design, weighing 0.78 kg, is complemented by a rotor inertia of 0.4x10^-4 kg·m^2, ensuring a balance of responsiveness and stability. Additionally, the unit is designed with robust vibration resistance, withstanding 0.5G along the X, Y, and Z axes over a frequency range of 10 to 55 Hz for a continuous duration, thereby enhancing its durability in demanding conditions.

Further emphasizing its suitability for industrial settings, the motor operates reliably within an ambient temperature range of 0 to +50°C and supports an operating ambient humidity level between 35 to 85% RH (no condensation). It is built to withstand harsh environments, with conservation temperature ratings from -20 to +70°C and proven impact resistance in accordance with established standards. The motor also meets stringent requirements with a minimum insulation resistance of 10 MΩ when a DC 500V Megger is applied, and it is designed to endure an AC 500V withstand voltage between the power input terminal and the cabinet for one minute. These features collectively ensure that the motor delivers consistent performance, making it an excellent choice for precision-driven industrial automation and control systems.
