{"title":"1000:1 Micro Metal Gearmotor HPCB 6V","handle":"1000-1-micro-metal-gearmotor-hpcb-6v","url":"/products/1000-1-micro-metal-gearmotor-hpcb-6v","description":"A 1000:1 micro metal gearmotor from Pololu's popular N20-size range, featuring a high-power 6V brushed DC motor with long-life carbon brushes (HPCB). The carbon brushes offer significantly longer motor life compared to the precious metal brush (HP) version, while delivering the same performance.\n\nWith the highest gear ratio in the series, this motor delivers extremely low output speeds and very high torque relative to its tiny size. At 6V with no load, the output shaft turns at approximately 33 RPM.\n\nKey Features\n\n\n1000:1 Gear Ratio – Extremely low speed with very high torque output\n\nCarbon Brushes (HPCB) – Longer motor life than precious metal brush versions\n\nHigh-Power Motor – 1.5A stall current for strong performance\n\nN20 Form Factor – Compatible with Pololu wheels, brackets, and encoders\n\nAll-Metal Gearbox – Durable spur gears for sustained operation\n\n\nSpecifications\n\n\nGear Ratio – 1000:1 (exact: 986.41:1)\n\nNominal Voltage – 6V\n\nNo-Load Speed – 33 RPM @ 6V\n\nNo-Load Current – 150mA (0.15A)\n\nStall Current – 1.5A\n\nStall Torque – 11 kg·cm (150 oz·in)\n\nCross Section – 10 × 12mm\n\nOutput Shaft – 3mm diameter, D-shaped, 9mm long\n\nTerminal Width – 2mm (wider than precious metal brush versions)\n\nTerminal Spacing – 6mm\n\n\n\nWarning: The 1000:1 gearbox can generate enough torque to damage itself. Avoid stalling the motor. Stall torque and current values are theoretical extrapolations. Keep operating current at 25% or less of stall current to maximise motor life.\n\n\n\nNote: HPCB terminals are 0.5mm wider and 1mm closer together than HP/MP/LP versions. HPCB motors are not compatible with Pololu's older optical encoders (#2590, #2591) or older magnetic encoders (#2598), but are compatible with the newer #3081 magnetic encoders.\n\n\nIdeal For\n\nApplications requiring very slow, controlled rotation\nHigh-torque mechanisms in small form factors\nLong-running robotics and automation projects\nPan/tilt mechanisms and slow actuators\n\n\nResources\n\nMicro Metal Gearmotor Datasheet (PDF)\nGearmotor Dimensions Drawing (PDF)\n","vendor":"Pololu","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13074,"title":"Default Title","sku":"PL-3070","price":53.3,"on_sale":false,"in_stock":true,"available_quantity":5,"option1":"Default Title"}]}
