Expect speed to slow as load approaches the limit, and consider heat and duty cycle when operating near stall.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003eUnder loads near the rated torque, speed will decrease as load increases; exceeding the rated torque can stall the motor or cause damage.\u003c\/li\u003e\n\u003cli\u003eSelf-locking means the output shaft remains fixed with no electrical power, which is handy for locks and curtains that need to stay in place.\u003c\/li\u003e\n\u003cli\u003eRotation direction can be altered by wiring configuration, simplifying installation in tight spaces.\u003c\/li\u003e\n\u003cli\u003eFor longevity, avoid continuous near-stall operation; provide adequate cooling or use intermittent duty to prevent overheating.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Bearings Canada","offers":[{"title":"Default Title","offer_id":52222453842239,"sku":"VXB0774HGZGX","price":95.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0887\/4750\/8031\/files\/12v-16rpm-dc-worm-gear-motor-high-torque_1.jpg?v=1772831832","url":"https:\/\/bearingscanada.com\/products\/12v-16rpm-dc-worm-gear-motor-70kg-cm-high-torque-t","provider":"Bearings Canada","version":"1.0","type":"link"}
