FingerTech “Silver Spark” 16mm gearmotors are compact, high-quality DC gearmotors designed for robotics and combat robots. Available in 22:1, 33:1, and 200:1 ratios, they offer a wide range of speeds and torque options for drive systems, lifters, and mechanisms. All gearboxes are interchangeable thanks to the common 14T motor pinion, allowing easy customization without desoldering.
محركات FingerTech “Silver Spark” بقطر 16 مم هي محركات تروس صغيرة وعالية الجودة مخصصة للروبوتات. تتوفر بنسب 22:1 و33:1 و200:1 لتوفير خيارات مختلفة من السرعة والعزم. تتميز بإمكانية تبديل علب التروس بسهولة بفضل ترس المحرك الموحد 14 سنًا دون الحاجة لفك اللحام.
The Silver Spark line of motors has the same 16mm diameter as the Gold Sparks, but the gears are a larger pitch. This means less worrying about stripping teeth in your bigger or heavier applications!
Extra-long 3mm shaft for mounting wheels directly with the option to use a bearing block for support on the wheel's far side.
Same 11mm face mount pattern as Gold Spark motors.
All-metal spur gearhead mated to a Mabuchi FK-050 motor.
8 different gear ratios for a wide range of rpm and torque to choose from. One twice as fast, and one twice as slow as the Gold Sparks!
Weights from 28 - 32grams (0.99 - 1.13oz). (see details)
