Product Description:

The 103F7852-8041 is a StepSyn Stepping Motor by Sanyo Denki. It operates with a DC24V source voltage that ensures efficient power delivery in industrial automation. This motor functions with a 1.5A phase input current and enables its operation in tough applications.

The 103F7852-8041 stepping motor moves with a smooth torque profile due to its rotor inertia measures as 0.4×10⁻⁴ kg·m². Accurate movements result from the combination of step angle technology with rotor inertia parameters. The motor successfully operates at 50/60Hz under AC1000V for 1 minute and guarantees electrical stability. Safety performance increases because this stepping motor maintains a minimum insulation resistance of 100MΩ at DC500V. The steady operating current with rated voltage enables the stepping motor to run efficiently with stable performance.

The pulling torque level the motor reaches is JL1 = 0.93×10⁻⁴ kg·m² while achieving notable mechanical performance. Its holding torque reaches 0.93 Nm, which enables stable positioning of the system. The 103F7852-8041 stepping motor enables accurate motion control because its basic step angle measures 0.72 degrees. Operating temperatures ranging between -10°C to +50°C grant the motor flexibility when utilized in various environmental conditions. This stepping motor operates within humidity ranges from 20% to 90% under ambient conditions without producing condensation to prevent system malfunction.

The weight of the 103F7852-8041 stepping motor equals 0.78 kg. This results in an ideal design relationship of mass to operational capability. The standard mounting interface of this device uses a flange dimension that measures 60mm × 60mm. The motor displays vibration resistance through 1.52 mm (P-P) amplitude between 10 and 55 Hz frequency. This helps in safeguarding the performance stability of the motor. External vibrations with sudden shocks do not cause interruptions because of the design characteristics. The component demonstrates durability under mechanical stress since it tolerates impact accelerations reaching 98 m/s².
