Product Description:
The Sanyo Denki’s 103-770-0167 represents a bipolar stepper motor optimized for positioning and controlled speed systems. Its 200 steps per revolution makes it fit into 3D printers, CNC and robotics machines. It has a 6-pin connector and provides a gear pulley shaft that leads to effective torque transmission when using belts.
The 103-770-0167 stepping motor functions on DC 5.1 V power supply while drawing 1 A current and provides smooth step movement through 1.8° stepping increments. Its classification under insulation class C allows up to 200°C thermal resistance thus promotes higher operational safety feature of working in hot conditions. The 103-770 stepping motor has a DC500V standard rated megohmmeter to detect an insulation resistance higher than 100 MΩ. It demonstrates the ability to withstand 1kVAC at 50/60Hz for 1 minute and maintains below 1mA leakage current to guarantee proper insulation between windings and motor frame. The 103-770 stepping motor features superior mechanical stability attributes, the axial play stays below 0.075mm when a force of 9N is applied yet the radial play remains within 0.025mm under 4.4N of force. The shaft runout tolerance has been set at 0.025mm to achieve high-grade rotary precision. Its 15N thrust force capacity together with a maximum radial force limit of 80N makes it execute operations with average mechanical demands.
The 103-770-0167 stepping motor’s mounting spigot maintains accurate positioning toward the shaft at 0.075mm and the mounting surface holds acceptable perpendicularity also at 0.075mm to achieve precise alignment during setup. A standing angle error of ±0.09° provides accurate step execution. The 103-770 stepping motor operates at ambient pressure 10⁵ Pa and temperature range of 32°F to 122°F at an elevation altitude below 3300 ft.
Frequently Asked Questions about 103-770-0167:
