103F7851-85CEA7
by Sanyo Denki
The Sanyo Denki 103F7851-85CEA7 is a high-precision stepping motor from the StepSyn Stepping Motors series, engineered by Sanyo Denki for demanding industrial automation tasks. This compact motor delivers a step angle of 1.8°/step and a holding torque of 0.88 Nm, ensuring accurate and repeatable positioning in assembly, pick-and-place, and indexing applications. Weighing just 0.6 kg and featuring a 60 mm flange size with a motor length of 46.5 mm, the 103F7851-85CEA7 excels where space constraints and reliable control are critical.
Designed for robust performance, this motor operates on a 100 V AC power supply and features Class B insulation rated up to 130 °C for thermal reliability in continuous operation. Its IP40 ingress protection rating guards against solid object intrusion larger than 1 mm, while the minimum insulation resistance of ≥100 MΩ at DC 500 V and dielectric strength of AC 1000 V, 50/60 Hz for 1 minute provide strong electrical isolation and safety. The motor endures vibration amplitudes of 1.52 mm p-p at 10–55 Hz across all axes for two hours, and can withstand impact shocks up to 490 m/s² (≤50 G) over 11 ms, making it well suited to environments with mechanical disturbances.
Beyond core motion control, the 103F7851-85CEA7 supports an operating humidity range of 20–90 % RH (non-condensing) and temperatures from –10 °C to +50 °C, ensuring stable operation across typical factory conditions. The combination of robust vibration and impact resistance, advanced insulation, and compact form factor enhances system efficiency, minimizes maintenance, and extends service life. The motor’s compliant design meets industry standards for safety and durability, offering engineers a reliable solution for precision positioning, conveyor indexing, and other automation tasks where performance and longevity are paramount.
