Product Description:
The Sanyo Denki built the 103H7124-1641 Stepping Motor, which operates as a tiny motion equipment in industrial automation systems. The device requires a 2A current per phase to power up reliably. This device incorporates both unipolar windings that connect to lead wires. Each phase has winding resistance, which measures 1.7 ohms according to the device rating.
The 103H7124-1641 stepping motor maintains an operating minimum holding torque, which equals 0.98 Nm. An applied torque becomes present when operating with two-phase energization. The measurement of phase-to-phase inductive value shows 3.1 mH. The specified values enable precise current management while operating the device. A stable motion response depends on rotor inertia equal to 0.245 × 10⁻⁴ kg·m². The precise positioning needs 1.8° as the step angle setting. The specified length of the motor device stands at 63.8 mm. The small dimension of this hardware enables straightforward integration into different systems. The square-shaped 103H7124-1641 stepping motor comes with a 56 mm frame dimension. The standard mounting requirements can be fulfilled by this form factor. The system weight of the unit stands at 0.8 kg. The insulation rating of the motor corresponds to Class B with an operating temperature limit of 130°C.
The 103H7124-1641 stepping motor starts its workable range at -10°C while also running up to +50°C. The maintained temperature level protects the system during prolonged usage time. This motor operates within a ventilated environment where humidity remains between 20% and 90% RH. Performance remains unaffected by water condensation in the design of the device. The allowed rotational irregularity of the shaft measures 0.025 mm. A proper design ensures all operations maintain minimal vibration levels. The protection grade of the motor reaches IP43 standards. The designed voltage boundaries extend from 12V to 200V DC.
