By drastically reducing the speed of the internal DC motor, the attached GB37 gearbox multiplies the output force, allowing you to drive heavy automated curtains, motorized display turntables, or custom robotic lifting arms. Its steady, low-speed rotation ensures that your mechanical components move smoothly without the jerky, uncontrollable motions associated with high-speed motors.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAll-Metal Gearbox Durability\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThe integrated GB37 tower-style reduction gearbox is constructed entirely from durable metal gears, ensuring a long lifespan and resistance to stripping under heavy loads.

This dual-functionality allows for highly flexible integration into complex Arduino or Raspberry Pi projects using an H-Bridge motor driver. The motor features clearly marked positive (red dot) and negative soldering terminals on the back, making it incredibly straightforward to wire up your custom forward and reverse control circuits.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003ePro Tip from Our Technicians\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eOur Sham Shui Po technical team strongly advises using a dedicated 12V motor driver with a high current rating to prevent stalling when pushing this\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cstrong class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003e7 RPM Gear Motor\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"ng-star-inserted\"\u003e\u003cspan\u003e \u003c\/span\u003enear its physical limits. While the motor can technically handle a 50kg.cm limit load, running it continuously at this extreme resistance will cause the coils to overheat and drastically shorten its lifespan. Always secure the motor using the six M3 threaded mounting holes on the faceplate to prevent the immense torque from twisting the motor out of its mounting bracket.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":48145312645271,"sku":"21PS002344-7RPM","price":40.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/12v-520-micro-gear-motor-7rpm-front.jpg?v=1787122104","url":"https:\/\/scccltd.com\/products\/12v-520-micro-gear-motor-7rpm-high-torque","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
