<div class="detailmodule_html"><div class="detail-desc-decorate-richtext"><p>Features:<br />1.Motor structure and performance: the 42 step two-phase micro motor has a 2-phase structure with a step angle of1.8&deg;. through subdivision control, smaller step angles can be achieved, making it suitable for high-precision positioning and control requirements.<br />2.High reliability design: this type of motor has been optimized by computer design, with high electromagnetic system operation efficiency, low temperature rise, insulation material, and the use of low loss silicon steel sheets and precision integrated stamping technology, resulting in high precision and low loss.<br />3.Installation convenience: equipped with internal thread installation standards, the threads are not easily damaged. The embedded design of the output shaft bearing eliminates the gearbox boss and can directly fit the installation surface, simplifying the installation process.<br />4.Low noise and smooth operation: this motor exhibits low noise levels during operation, making it suitable for applications that require high levels of quietness, such as 3d printers, engraving machines, etc.<br />5.Wide range of applications: suitable for 3d printers, automatic screw machines, office photocopiers, medical equipment, robots, cnc machine tools, workshop equipment, etc.</p> <p>Parameters:<br />Product name: 42 step motor<br />Manufacturer model: 42dyb311c-21d8 (international model 17hs4023)<br />Wire: Xh-2.54 100cm/4-pin dupont wire 100cm (optional)<br />Number of phases: 2 phases<br />Step angle: 1.8 &deg;<br />Rated voltage: Dc3.6v<br />Rated current: 1.0a<br />Shaft diameter: 5mm<br />Phase resistance: 3.6&Omega;&plusmn;10%<br />Phase inductance: 3.5mh&plusmn;20%<br />Holding torque: 0.1 n.m min<br />Starting speed: 500rpm<br />Operating speed: 700rpm<br />Insulation resistance: 100m&Omega;min<br />&nbsp;<br />package&nbsp;include:<br />42 stepper motor*1<br />Connection line*1<br /><br /></p></div></div>
