Product Description:
The 103F7851-85CEA7 StepSyn Stepping Motor is a precision motor that is designed for accurate motion applications requiring accuracy, electrical stability, and mechanical resilience. Manufactured by Sanyo Denki, this compact-sized motor comes with a 60 mm flange size and 46.5 mm motor length, being best suited where installation flexibility is required without compromising torque and operational consistency.
This motor operates on a 100V AC power supply to offer compatibility with high-voltage industrial equipment and ensure stable power delivery over long periods. The insulation of this motor falls under Class B, which offers thermal resistance up to 130°C. This class of insulation also allows the motor to operate reliably in thermally challenging conditions while ensuring electrical integrity over a long period. This motor’s IP40 protection provides protection against solid object ingress larger than 1 mm and is appropriate for environments with very low exposure to dust or liquids. The working temperature range of this motor is -10°C to +50°C, thus proving its versatility in wide temperature ranges. This motor also accommodates humidity levels of 20% to 90%, as long as there is no condensation.
For electrical safety, this motor is tested to withstand AC 1000V at 50/60 Hz for one minute under controlled test conditions. This motor has a minimum insulation resistance of 100 MΩ when tested with DC 500V, which further supports its functionality in current leakage prevention and electrical faults. The 103F7851-85CEA7 StepSyn Stepping Motor is capable of sustaining vibration amplitudes of 1.52 mm (P-P) over a frequency range of 10 to 55 Hz. This motor also provides robust impact resistance as it can withstand 490 m/s² acceleration for 11 milliseconds to function under physical shock without any mechanical failure.
Frequently Asked Questions about 103F7851-85CEA7:
Q: How does the Class B insulation help in extended operation?
A: Class B insulation on model 103F7851-85CEA7 supports up to 130°C, reducing thermal degradation. This ensures longer motor lifespan in heated industrial environments.
Q: Why is IP40 protection suitable for this motor application?
A: IP40 protects against small solid particles but not moisture. It's ideal for indoor machinery not exposed to dust-heavy or wet environments.
Q: Why is AC1000V withstand voltage important for 103F7851-85CEA7?
A: It helps prevent internal breakdown during voltage spikes. This is vital for electrical reliability in high-voltage systems.
Q: What role does 100MΩ insulation resistance play in motor safety?
A: High insulation resistance limits leakage current and electrical noise. This protects controllers and ensures signal stability.
Q: What is the function of the 10–55 Hz vibration range testing?
A: It simulates realistic operating conditions over typical machine vibration frequencies. Ensures motor does not lose step or fail.
