Product Description:

The highly adaptable 103G807-5790 stepper motor is made by one of the renowned manufacturer Sanyo Denki. The manufacturer is well known for creating high-demand and easy-to-use machinery for business and industrial applications.

The 103G807-5790 stepper motor is designed for precision motion with an angle of 1.8° per step and offers smooth and accurate positioning by making it ideal for 3D printers and other systems that require reliable movement. Built to handle substantial workloads, this StepSyn stepper series motor operates with a current consumption of 6 amps DC. The efficient metal housing features a silver front plate and a gray rear casing which aids in ensuring durability while also aiding in heat dissipation. The motor includes a single, round stainless-steel shaft with a chamfered end offering a secure and stable mechanical interface. It also comes with a flange mount that includes four mounting holes for easy and secure installation. The motor is installed with a set of color-coded wires bundled at the rear by making it easy to connect to a compatible driver.

The 103G807-5790 stepper motor performs reliably in environments with temperatures ranging from -10°C to 50°C and can be stored safely between -20°C and 65°C. The design also accommodates a wide range of humidity from 20% to 90% during operation and 5% to 95% in storage as long as there is no condensation. The motor is tested with 12 vibration sweeps in each of the X, Y and Z directions. For shock resistance, it contains 490 m/s² of acceleration for 11 milliseconds in a half-sine waveform and holds EMC protection to maintain vigorous working.
