Product Description:
Sanyo Denki produces motion control products of high performance. The industrial automation system from this company integrates the 103H7123-0140 StepSyn stepping motor into its design. A 2-phase stepper motor functions using direct current voltage of 24V with a 1.8° step angle design that enables accurate positioning.
This 103H7123-0140 stepping motor requires a frame dimension of 56mm square accompanied by a weight of 0.65 kg. The design presents a combination of size efficiency for industrial purposes. The motor exhibits a holding torque equal to 0.83 N·m while offering a single-shaft configuration. The design of this motor enables controlled motion operations. The motor successfully operates electrical loads because it features 0.6 Ω wiring resistance and 0.8 mH inductance per phase. This stepper motor establishes a maximum thrust capacity of 15N, which makes it suitable for applications that need sustained axial force delivery. The rated current of 103H7123-0140 stepping motor reaches 3A per phase. However, the wire-wound current stands at 2A per phase to provide stable torque during operation. Quick response is supported by the rotor inertia, which equals 0.21 × 10⁻⁴ kg·m². A rubber coupling enables the motor to reach a getaway torque value of 0.94 × 10⁻⁴ kg·m². The motor stands safe under electrical stress because it can endure 1kVAC at 50/60Hz for one minute. The wiring structure increases operational performance while sustaining efficient operation during demanding situations.
The 103H7123-0140 stepping motor functions effectively within a temperature range between -10°C and +50°C. This stepping motor operates in different humidity levels between 20% to 90% RH (non-condensing). The shaft type produces a single output to provide mechanical components with direct coupling. The shaft accepts radial forces reaching 52N in its ending section and expands to 123N along from 15mm from the shaft. The product features B (+130°C) insulation, which allows for long-term reliable operation.
