Product Description:

The Sanyo Denki 103-718-0344 is a high-performance and high-accuracy stepping motor that belongs to the StepSyn Stepping Motors series. It has a step angle of 1.8 degrees per step to deliver precise and accurate movement for industrial use. It has a rated voltage of 100-120 VAC, making it functional in different industrial settings. Relative humidity is another crucial factor, and it is supposed to be within 20% to 95%. Moreover, it is capable of operating within a temperature range of -10 degrees C to +50 degrees C, which makes it perfect for some tough situations.

This motor has two poles and can be connected with both the unipolar and bipolar windings, which ensures various types of electrical connections. The holding torque is 0.88 Nm for small models and up to 19 Nm for large models, providing high power and steady operations. It has a maximum winding temperature of 80 K, and it maintains constant efficiency with continuous use. It has axial and radial play, with maximum axial play limited to 0.075 mm while the radial play is 0.025 mm, thus making it strong even under heavy loads. Furthermore, it complies with high insulation resistance and a dielectric voltage endurance of DC500V with a minimum resistance of 100 M? between the winding and the frame.

The 103-718-0344 motor is used widely in robotics, CNC equipment, and industrial automation since it offers high torque, high precision, and lasts longer. It has readily usable connectors and lead wires, therefore making it very flexible and enabling it to be installed in various systems. Because of its rigid construction, durability, and flexibility in terms of voltage compatibility, it is suitable for industries related to motion control technology.
