Product Description:

The Stepper Motor 103H8221-5241 by Sanyo Denki is a unipolar motor built for precision driven industrial applications. This motor ensures accurate positioning and smooth operation with a durable internal wiring structure and efficient winding design. It delivers consistent torque and stability.

The 103H8221-5241 stepper motor runs on a 6 Ampere wiring current. This motor delivers efficient power distribution for tasks requiring high performance. It employs a 2-phase full step energization method to ensure precise angular positioning with a 1.8° step angle per step. The unipolar winding setup optimizes current movement while ensuring better efficiency. This motor follows a specific excitation sequence to ensure a clockwise rotation when driven correctly. The internal wiring configuration includes six lead wires with terminals marked as Orange (11), White (9) and Blue (7) for one coil and Red (1), Black (3) and Yellow (5) for the other. This structured arrangement provides consistent electrical connectivity. The connector pin arrangement follows a structured order with designated polarities to facilitate proper wiring and installation. This motor features an optimized structure which delivers steady torque output together with low vibration performance levels. This StepSyn stepper motor operates between temperatures that span -10 °C to +50 °C of ambient conditions.

This 103H8221-5241 stepper motor works best under humid conditions (20 % to 90 % RH without condensation). Storage temperature ranges extend from – 20 °C and + 65 °C. This model can be stored under humidity levels between 5 percent RH to 95 percent RH. Operation of this stepper motor is possible at altitudes which do not exceed 1000 m. This stepper motor delivers reliable torque stability at minimal vibration levels which makes it highly suitable for applications requiring precise performance.
