Product Description:
The 103H8221-0642 Stepper Motor comes under the StepSyn Stepping Motors series that is made by Sanyo Denki. With the precise and smoother operation capability it is well suited for demanding operations.
This 103H8221-0642 stepper motor can hold 2.15 N·m torque when it is energized but not rotating due to which it is able to maintain its position under load. This model's physical weight is 1.5 kg which implies that it is a stronger, more robust build suitable for industrial applications. The electric pulse moves its shaft 1.8 degrees and it takes 200 steps to complete one full 360 turn which is standard for stepper motors and provides a balance between precision and speed. It has multiple wires for power and control signals that terminate in a circular connector which improves reliability and makes the installation and maintenance easier. For acceleration and deceleration, it has rotor inertia of 7.93 oz·in² which allows faster dynamic response. This motor has a moderate length which makes it ideal for applications with limited space and is able to generate standard torque. It is featured with a standard mounting flange with four mounting points for secure installation.
The outer shaft of this 103H8221-0642 stepper motor falls within 6mm to 8mm diameter range. The dimension of its stepper movement or form factor is 3.39 inches which ensures proper fitment in systems designed for this specific size. The winding phase of this motor requires 3A of current to operate which suggests it is powerful and requires a capable stepper driver. It uses a two coil system (bipolar) that requires an H Bridge driver and offers higher torque than unipolar ones but requires a more complex driver.
Frequently Asked Questions about 103H8221-0642:
Q: How does the 1.8 step angle in the 103H8221-0642 Stepper Motor improve precision?
A: The 1.8 step angle ensures smooth and precise motion control with 200 steps per revolution. This results in reduced vibration and improved positioning accuracy in industrial applications.
Q: Why is a bipolar coil system used in the 103H8221-0642 Stepper Motor?
A: The bipolar coil system provides higher torque and efficiency than unipolar configurations. It requires an H-Bridge driver, which enhances power handling and overall performance.
Q: How does the 2.15 N·m holding torque benefit industrial applications?
A: The high holding torque prevents unwanted shaft movement when the motor is stationary. This ensures stable positioning under load, making it ideal for CNC and robotics.
Q: What role does the 3A per phase current rating play in the 103H8221-0642 Stepper Motor?
A: The 3A per phase current enables the motor to generate significant torque. This ensures strong and stable motion for demanding applications like conveyor systems and automated machinery.
Q: Why is a circular connector used instead of standard open wiring in this stepper motor?
A: The circular connector improves reliability by preventing loose connections and reducing electrical interference. It also allows for quick and secure installation in industrial automation systems.
