Product Description:
The 103H7123-6211 is an AC stepping motor manufactured by Sanyo Denki to serve as a precise motion control device for industrial and automation systems. It functions without a degrade on sites that have humidity levels between 20% to 95% RH unless condensation forms in the surrounding area and temperature up to 45°C.
The 103H7123-6211 AC stepping motor has a 3 pounds weight accompanied with IP40 protection scheme that defends against solid objects. Its 2 A per phase rating and 0.83 Nm rotor locked turning effect provides suitable torque performance for low-speed systems. The 103H7 AC stepping motor operates at 72 RPM when running on 60 Hz power frequency but continues delivering 60 RPM at 50 Hz to support different frequency control systems. It accepts standard voltage of 200VAC with tolerance for connection with different power supply types. The 103H7 AC stepping motor incorporates the LBK-0401D00 encoder that generates 1000 pulses every revolution and can be installed on the rear to provide immediate feedback for closed-loop control needs. It supports electrical connections by UL3266 AWG22 lead wires and the 103H7 AC stepping motor passes the 1 KV AC test for 60 seconds without exceeding 1 mA leakage current.
The 103H7123-6211 AC stepping motor features 1.8-degree step angle and performs electrical testing using a DC 500V megger to show an insulation resistance greater than 100 MΩ. It has a resolution of 200 steps per revolution and equipped with a 6-pin JST connector compatible with bipolar driver configurations to allow flexible wiring options. The 103H7 AC stepping motor offers minimal slippage and enhanced mechanical efficiency during high-load operations due to its gear pulley shaft, thus optimized torque transmission particularly in belt-driven systems is achieved.
Frequently Asked Questions about 103H7123-6211:
Q: Why is a 1.8° step angle significant in this stepping motor?
A: A 1.8° step angle provides smoother rotational precision and high resolution. This ensures accurate micro-stepping, ideal for fine positioning tasks.
Q: What is the function of the LBK-0401D00 encoder in the 103H7123-6211 motor?
A: It provides 1000 pulses per revolution for precise speed and position feedback. This enhances system control in closed-loop applications.
Q: How does the 103H7123-6211 support safe electrical insulation?
A: It passes a 1 KV AC dielectric test with less than 1 mA leakage, proving its insulation reliability. This safeguards connected systems against internal shorts or overvoltage faults.
Q: Why is the 200VAC rating with tolerance important in the 103H7123-6211 AC motor?
A: It allows the motor to operate reliably across different industrial power supply standards. This flexibility simplifies integration into global automation platforms.
Q: How does the motor’s 2 A per phase rating influence performance?
A: It ensures stable current delivery, preventing underpowering during high torque demand. This keeps step losses to a minimum during rapid changes in load.
