Product Description:

The Sanyo Denki proficient Stepper Motor with part number 103H7852-7021 provides cutting-edge technology and is designed for mechanical applications requiring precision in multiple operations. A renowned and superior product design firm, Sanyo Denki focuses on producing top-notch motors, drives and sensors for use in many kinds of industrial automations.

The 103H7852-7021 stepper motor behaves as an accurate driving part consisting of two shafts and five stages of stepping operations required for correct rotations. A 60 mm square frame shape together with its 0.72° step angle provides motor users with precise and smooth positioning abilities. This series StepSyn stepper motor maintains continuous reliability by operating efficiently at 0.75 amps per phase. It displays an efficient amount of holding torque with 139 in-oz which equals 98 N-cm and aids in maintaining a firm grip on its position without losing friction. The rotor maintains a perfect combination of active responsiveness and stability because of its inertia moment rate which is set to 0.0057 oz-in-sec² (0.0400 kg-cm²). This motor provides excellent control of rotational movement due to its design features. Its sturdy small weight build-up design allows easy integration of the motor into diverse systems of industries.

This 103H7852-7021 stepper motor holds a metric-standard design that carries UL certification with CE marking to guarantee safety compliance and adherence to high standards of protection. It mainly shows excellent performance in humid conditions since it operates correctly in moisture levels by gaining almost 90% humidity tolerance. Under difficult environmental situations, this motor functions persistently with an EMC protection. Multiple setup options can be achieved through the motor's double-shaft layout due to its design flexibility.
