{"product_id":"spmxsm3001","title":"Firma 2100Kv Brushless Sensored Crawler Motor (SPMXSM3001)","description":"\u003cdiv class=\"product_description\"\u003e\n  \u003cp\u003eFirma 2100Kv Sensored Brushless Crawler Motor is a high-performance powerplant designed for 1\/10-scale crawlers, rock racers, and trailers powered by 2S–3S LiPo packs. It features a low-cog 4-pole, 8-magnet rotor, CNC-machined aluminum housing, insulated high-purity copper windings, and a precision 3.175 mm (1\/8\") output shaft with durable bearings for smooth rotation. Preinstalled with 3.5 mm gold-plated bullet connectors for easy installation. This motor serves as an excellent upgrade from 540 brushed motors with the same diameter and mounting pattern, provided the vehicle accepts pinions with a 1\/8-inch bore. A Spektrum FIRMA 60A Sensored Brushless Smart Crawler ESC is required for operation.\u003c\/p\u003e\n  \u003cp\u003eDesigned to balance speed and torque for trail and scale crawling, the motor uses a 4-pole sintered rotor and features polarity protection via an integrated magnetic encoder, ensuring consistent rotor-position signals across all three phases. The waterproof sensor wire includes a locking plug and gasket, and the hardened steel 1\/8\" shaft along with precision bearings delivers durability in rugged terrain. This configuration provides smooth throttle response and efficient power delivery for crawlers upgrading from brushed systems.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Spektrum (SPM)","offers":[{"title":"Default Title","offer_id":47909224022068,"sku":"SPMXSM3001","price":159.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/6653\/8292\/files\/SPMXSM3001.jpg?v=1781742365","url":"https:\/\/nankinhobby.com\/products\/spmxsm3001","provider":"Nankin Hobby","version":"1.0","type":"link"}
