Product Description:
The 103H8221-6241 Stepper Motor is an excellent motion control solution designed for precise positioning applications. This module by Sanyo Denki known for its reliability and efficiency belongs to the StepSyn Stepping Motors series
This 103H8221-6241 stepper motor has a square-shaped frame with 86 mm x 86 mm dimensions which is a common size for NEMA 34 stepper motors. It weights 1.5 kg which indicates a robust structure suitable for applications requiring moderate torque and precision. It is able to provide a torque of 2.74 Newton-meters, which determines its ability to handle mechanical loads. The axial movement (end play) of the motor shaft is 0.075 mm when a 10 Newton force is applied. It ensured precision in applications with this small thrust play. This StepSyn Stepping Motors series model is a 2 phase stepper motor, which is the most common type, typically controlled using bipolar or unipolar stepper drivers. It functions on AC power despite being a stepper motor which indicates it might be a hybrid stepper or servo stepper with an AC driver. Its actual step movement can vary by ±5%, which is a common accuracy level for stepper motors. The maximum temperature rise of the windings under normal operating conditions is 80K and it may need proper cooling or heat dissipation for continuous operation.
The 103H8221-6241 stepper motor has a high insulation quality and ensures it stands high voltages without breakdown. This module has low internal losses and can handle higher currents with its winding resistance of 0.18 Ω per phase. These features make it suitable for applications that require positioning such as CNC machines, 3D printers, automation systems, robotics, medical equipment and industrial automation control.
Frequently Asked Questions about 103H8221-6241:
Q: How does the 1.8° step angle of the 103H8221-6241 stepper motor improve positioning accuracy?
A: The 1.8° step angle ensures finer resolution, providing 200 steps per revolution for precise positioning. This enhances motion control, making it ideal for CNC and robotics applications.
Q: Why is the 6A per phase current rating of the 103H8221-6241 important for performance?
A: A 6A per phase current rating allows the motor to generate higher torque with stability. This ensures consistent motion control in high-load applications like automation and 3D printing.
Q: How does the 0.18 Ω winding resistance affect the efficiency of the 103H8221-6241 stepper motor?
A: A low winding resistance of 0.18 Ω minimizes heat buildup, reducing energy loss. This helps improve efficiency and prolongs the motor’s operational lifespan.
Q: What role does insulation resistance of 100MΩ at 500VDC play in the 103H8221-6241?
A: High insulation resistance (100MΩ at 500VDC) prevents electrical leakage, ensuring safe operation in high-voltage environments. This improves motor durability and protects against insulation breakdown.
Q: Why is a thrust play of 0.075 mm beneficial for precision applications?
A: Minimal thrust play (0.075 mm at 10N load) reduces unwanted axial movement, improving accuracy. This is essential for applications requiring tight mechanical tolerances like medical devices and precision automation.
