{"title":"Metal DC Geared Motor - 6V","handle":"metal-dc-geared-motor-6v","url":"/products/metal-dc-geared-motor-6v","description":"A compact all-metal DC gearmotor family from DFRobot, sold here as one motor in seven gear ratios. Every version shares the same 6 V brushed motor, the same 4 mm D-shaped output shaft and the same mounting footprint — the only thing that changes is the gearbox, which trades speed against torque from a slow, very strong 15 RPM / 10 kg·cm right through to a brisk 357 RPM / 0.7 kg·cm.\n\nMetal gears throughout give these a much longer life than the plastic-gearbox motors they compete with, which is why they hold up in classroom robots that get rebuilt every term. Pick the ratio by the job: high torque for lifting, driving loaded wheels and pan-tilt mechanisms; high speed for light drive wheels and anything that needs to actually get moving.\n\nCompare the seven speeds\nAll seven are the same price and the same physical motor. No-load speed is measured at 6 V; torque figures are locked-rotor (stall).\n\n\n\nSpeed\nStall torque\nGear ratio\nGearbox length\nNo-load current\nWeight\nSKU\n\n\n\n15 RPM10 kg·cm478:127 mm50 mA74 gDF-FIT0495-A\n20 RPM7.5 kg·cm362:127 mm50 mA74 gDF-FIT0495-B\n73 RPM2.5 kg·cm99:123 mm50 mA72 gDF-FIT0495-E\n97 RPM1.9 kg·cm75:123 mm50 mA70 gDF-FIT0495-F\n162 RPM1.2 kg·cm45:121 mm50 mA68 gDF-FIT0495-G\n191 RPM1 kg·cm34:121 mm60 mA68 gDF-FIT0495-H\n357 RPM0.7 kg·cm20:119 mm50 mA66 gDF-FIT0495-I\n\n\n\nWhich one should I pick?\n\n\n\nIf you are building\nChoose\n\n\n\nA lifting arm, winch or geared-down joint15 RPM · 10 kg·cm\nA heavy mechanism that still needs to move visibly20 RPM · 7.5 kg·cm\nA loaded robot chassis73 RPM · 2.5 kg·cm\nA small two-wheel drive robot (the usual pick)97 RPM · 1.9 kg·cm\nQuicker drive wheels that still need pull162 RPM · 1.2 kg·cm\nA line-follower or light chassis that needs pace191 RPM · 1 kg·cm\nThe fastest option, for light loads only357 RPM · 0.7 kg·cm\n\n\n\nShared specifications\n\n\nRated voltage6 V DC\nOperating voltage range2–7.5 V\nLocked-rotor (stall) current0.6 A\nOutput shaft4 mm diameter, D-shaped flat\nGearboxAll-metal gear train\nMotor typeBrushed DC, two-wire, no encoder\nOperating temperature−20 °C to +60 °C\nWeight66–74 g depending on gearbox\n\n\n\nIdeal for\n\nMobile robot drive wheels and robot chassis\nPan-tilt heads, robotic arms and geared joints\nSmall conveyors, actuators and automated mechanisms\nSTEM and classroom robotics builds that need gears that survive the year\n\n\nA note on driving them\nThese are plain two-wire brushed DC motors with no encoder and no built-in driver — you will need an H-bridge motor driver to run one from a microcontroller. Stall current is 0.6 A per motor, so size the driver and supply for the number of motors you are running simultaneously. If you need closed-loop speed or position control, look at the encoder versions of this motor instead.\n\nPackage contents\n\n1× Metal DC Geared Motor (6 V, in the gear ratio you select)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[{"name":"Speed","values":["15 RPM · 10 kg·cm","20 RPM · 7.5 kg·cm","73 RPM · 2.5 kg·cm","97 RPM · 1.9 kg·cm","162 RPM · 1.2 kg·cm","191 RPM · 1 kg·cm","357 RPM · 0.7 kg·cm"]}],"variants":[{"id":13623,"title":"15 RPM · 10 kg·cm","sku":"DF-FIT0495-A","mpn":"FIT0495-A","price":19.85,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":387,"option1":"15 RPM · 10 kg·cm"},{"id":13615,"title":"20 RPM · 7.5 kg·cm","sku":"DF-FIT0495-B","mpn":"FIT0495-B","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":78,"option1":"20 RPM · 7.5 kg·cm"},{"id":13610,"title":"73 RPM · 2.5 kg·cm","sku":"DF-FIT0495-E","mpn":"FIT0495-E","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"73 RPM · 2.5 kg·cm"},{"id":13583,"title":"97 RPM · 1.9 kg·cm","sku":"DF-FIT0495-F","mpn":"FIT0495-F","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":8,"option1":"97 RPM · 1.9 kg·cm"},{"id":13560,"title":"162 RPM · 1.2 kg·cm","sku":"DF-FIT0495-G","mpn":"FIT0495-G","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":13,"option1":"162 RPM · 1.2 kg·cm"},{"id":15435,"title":"191 RPM · 1 kg·cm","sku":"DF-FIT0495-H","mpn":"FIT0495-H","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":27,"option1":"191 RPM · 1 kg·cm"},{"id":13609,"title":"357 RPM · 0.7 kg·cm","sku":"DF-FIT0495-I","mpn":"FIT0495-I","price":19.85,"on_sale":false,"in_stock":true,"available_quantity":22,"option1":"357 RPM · 0.7 kg·cm"}],"documents":[{"title":"Mechanical dimension drawing (FIT0495)","type":"mechanical_drawings","type_label":"Mechanical Drawings","url":"https://dfimg.dfrobot.com/enshop/image/data/FIT0495/Dimension.jpg","link":false,"file_extension":"JPG","description":"Dimensioned drawing of the motor body, gearbox and 4 mm D-shaft, from DFRobot.
