Product Description:

The Sanyo Denki company produces the 103H5208-0410 StepSyn Stepping Motor. It ensures high repeatability in step motion for industrial automation processes. The motor produces a holding torque strength of 0.3 Nm.

The operation efficiency of 103H5208-0410 stepping motor requires a phase current rating of 1.2 A. Each phase of the wiring demonstrates a 2.9 Ω resistance value. Each phase of the stepping motor has a wiring inductance of 3.4 mH. StepSyn Stepping Motor operates with a step angle of 1.8 degrees per step. The motor functionally operates using a typical DC voltage supply of 24V. This stepping motor comes with dimensions of 42mm square, which is equal to 1.65 inches square. Stable motion occurs because the rotor inertia measures 0.056 x10⁻⁴ kg·m². The 103H5208-0410 stepping motor mass amounts to 0.29 kg. Its framing size measures 0.64 lbs, which supports compactness. This motor implements a bipolar winding structure through its lead wire connections. The required connector cable for this motor features the reference number 4835710-1. The motor accepts humidity values between 40% and 90% RH without creating condensation buildup. The motor operates between -10°C to +50°C under ambient conditions. The motor can be stored between -20°C and +60°C alongside other temperatures within this range.

Installation of the 103H5208-0410 stepping motor depends on a flange system. A stable installation between the stepper motor and its flange base happens through four M3 screws. One minute of applied 500 V AC proves the dielectric strength capabilities of this device. The electrical insulation keeps the motor safe through this specification under operating conditions. The designed motor serves precise motor movement applications. The small size of this equipment fits well into confined installation spaces. The device delivers correct step movements along with dependable torque operation.
