These are often used in gauges for motorcycles and cars to replace the old-style fully-analog type. They have extremely fine step precision of about 1\/2 a degree per step, 600 steps for single stepping, fast response for quick movements, and a range of  ~315° degrees. Their smooth motion makes good for small projects that need a dial indicator, and more precision motion than you may get with a needle gauge.\u003c\/p\u003e\u003cp\u003eSince this is a bi-polar stepper motor you do need to have some sort of H-Bridge to drive it. A L293D or TB6612 will do the job nicely. If you have a microcontroller that can drive 200 ohm loads you might be able to use the direct pins without extra MOSFETs, just remember to include kickback\/flyback protection diodes!\u003c\/p\u003e\u003cp\u003eNote that the motor is quite 'weak', not good for moving anything but a light indicator. We include a red-line dial that fits nicely on top by pushing onto the needle shaft.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cp\u003eDatasheet - we don't have an exact datasheet but did find one for a compatible gauge, which may be helpful (although not guaranteed to be identical)!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAxial Force Maximum: 150N\u003c\/li\u003e\n\u003cli\u003eAxial Pull Force Maximum: 100N\u003c\/li\u003e\n\u003cli\u003eRadial Force Maximum: 12N\u003c\/li\u003e\n\u003cli\u003eRotation Angle Maximum: 315°\u003c\/li\u003e\n\u003cli\u003eCoil Resistance: 260 ohm\u003c\/li\u003e\n\u003cli\u003eGeneral Tolerance: ± 0.1 \/ ± 5°\u003c\/li\u003e\n\u003cli\u003eRotation Angle Maximum: ~315°\u003c\/li\u003e\n\u003cli\u003e600 steps per 'rotation' (315 degree rotation)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e​Red-Line Dial Diameter: 13mm \/ 0.5\"\u003c\/li\u003e\n\u003cli\u003eRed-Line Dial Length: 42mm \/ 1.65\"\u003c\/li\u003e\n\u003cli\u003eDial Thickness: 1mm \/ 0.04\"\u003c\/li\u003e\n\u003cli\u003eMotor Diameter: 32mm \/ 1.3\"\u003c\/li\u003e\n\u003cli\u003eMotor Thickness (w\/o pins): 9mm \/ 0.35\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":46039286186044,"sku":"tlo1787257351341","price":7.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/6985\/2220\/files\/automotive-gauge-stepper-motor-x27168_1.jpg?v=1787257359","url":"https:\/\/www.mossheath.com\/products\/automotive-gauge-stepper-motor-x27168","provider":"My Store","version":"1.0","type":"link"}
