COPAL 30:1 Gearmotor

Great power and speed, light weight and very efficient, this incredible little motor is one great value, and at under 1 ounce each!

The built-on 30:1 gearhead provides a great amount of torque to the wheels while still being quite zippy. We recommend using our Foam Tires with this motor, as they provide good shock absorption for the small gearhead (not recommended for larger then 1.5" diameter wheels). Pre-wired with about 4" long leads.

Voltage: 4.8-9V
Only 1.43" long, 5/8" diameter
weight: .88oz
52.49 oz-in torque @ 12V
29.16 oz-in torque @ 6V
770rpm @ 12V
390rpm @ 6V
stall at 1.3a (Avoid stalling, to prevent gear damage)
3mm diameter shaft with 5mm long flat

COPAL 50:1 Gearmotor

This little motor takes the Copal line another step further with its all-metal gears at a ratio of 50 to 1. We've tested this motor extensively, and were extremely impressed at it's performance.

There are now TWO different versions of this motor- one with a 6V motor, and one with a 12V motor. Since we know many builders will opt to overvolt these motors anyway to 12+ volts, we had Copal develop a new 6V version of this motor, just for the Robot MarketPlace! Both motor models have wire leads soldered onto the back. Check out the stats below.

Note that this motor's gearbox is exposed, so it's best for use in a bot where it is enclosed. If you need to, you could wrap a layer of thin CF or foil around the gearbox if you're worried about grit getting inside, or better yet, check out our Lexan Mounts made just for this motor, which also keep the gearbox enclosed.

COPAL 60:1 Gearmotor

This is a very popular motor for Antweight robots. Some of the top robots out there use this motor for drive. Very high power, light weight and very efficient, this incredible little motor is one great value, and at under 1 ounce each!

The built-on 60:1 gearhead provides a great amount of torque to the wheels. We recommend using our Foam Tires with this motor, as they provide good shock absorption for the small gearhead. Pre-wired with about 4" long leads.

Voltage: 6-12V
Only 1.57" long, 5/8" diameter
weight: .88oz
71.44 oz-in torque @ 12V
50.49 oz-in torque @ 6V
410 rpm @ 12V
220rpm @ 6V
stall at 1.3a
3mm diameter shaft with 5mm long flat

Micro Geared Motors

These are the smallest gearmotors we've found, nice durable quality too!

High quality all-metal gears in all models. Select high torque or high speed.

The entire motor with gears weighs only .3 ounces!  They are rated for 5.0V DC, but we have tested and run them at 9.0V, even up to 12V. Many tires/wheels can be directly mounted to the diameter output shaft.Note that the 35:1 is a bit larger than the others. Great for use in Sumo robots!

Please note the shafts are different on these models. For example, the 50:1 comes with a longer, 12mm long shaft, while the 75:1 comes with a stubby 5mm shaft. The 56:1 motor has an even longer shaft, but is only 2mm instead of 3mm diameter. Please review the chart below when making your selection.

With these motors we will see a new evolution of tiny bots. YES, the prop adapter and aluminum hubs we sell will fit on most of these motors!

B-Series Beetle Gearmotors

These are some awesome motors for your Beetleweight (3 pound) robot, or for a steroid-powered Antweight. Also great for applications that require high-torque lifting or movements of arms, etc.

We haven't seen a motor this good since the old Escap 33:1,

All-metal planetary gearbox with metal gears. Available in 3 different gear ratios, whether you need a super-zippy 16:1, which is all about the speed, up to a monstrous torque 104:1 with a huge 247oz-in of torque!

Check out these numbers:

Tamiya 70093 Single, 3-Speed Crank Axle Gearbox

The 3-speed crank-axle gearbox looks very much like half of the twin-motor gearbox (above); it even uses the same gears. Gear it for power or speed. A FA-130 motor is included.

Great for a high torque or high speed adjustable drive wheel or lifter arm. Get 2 for a two-wheel drive bot and cut the shaft for whatever side you need. Some assembly required.

Weight: 1.4 oz.
Ratios: 17:1, 58:1 or 204:1
Current: 1.0A @ 3V
can be run safely up to 8.4V

Tamiya 70103 Universal Gearbox

The Universal Gear Box works well in a variety of applications and can be mounted several ways. A hex shaft and a threaded shaft are included to give the builder flexibility in design. The plastic gears and metal gear box are all high quality. A FA-130 motor is included.

This motor uses a thin metal frame and mounts, making it very durable for tough applications. This is Tamiya's smallest gearbox. Some assembly required.

Gear Ratios: 101:1, 269:1, and 719:1
can be run safely up to 7.2V

15256 'Hyper Dash 2' Replacement Racing Motor

This is an upgraded motor replacement for the above (70097 and 70093) dual and single motor gearboxes. This motor is a stronger, faster version than the ones that come with the standard kits. 19,300rpm no load at 3V! Same size as the stock motor- 25.1 x 20.1mm, 17.0 grams, 2.0mm shaft.

Tamiya 72001 Planetary Gearmotor

This Planetary Gear Box is a VERY durable, precise, high quality gearbox with a RE-260 motor built into the gearbox. A wide range of gear ratios can be attained, depending on how many stages you decide to add (8 different possibilities!). Two kinds of crank arms are supplied for a wider range of functions.

Buy multiple motor kits and you can combine stages to further increase torque and decrease speed. 3 kits in series would provide 1 shaft revolution every 4 days! Great for experimenting with gear ratios. Some assembly required.

Weight: 2.75 oz
Ratios include 4, 5, 16, 20, 25, 80, 100, and 400:1 (each change will reduce the overall weight as you remove a section)
No-load speed of motor is 10,500 rpm, stall torque is 15gcm @ 3V (no geardown)
Current: 1.0A @ 3V
can be run safely up to 8.4V

Tamiya 72002 High Speed Gearmotor

When you need a little more speed than torque, this is the gearmotor for you. Two gear ratios are possible, and a RE-260 motor is included. Several styles of crank arms are included.

Great for a high speed drive wheel. Some assembly required.

Tamiya 72005 6-Speed Gearbox H.E.

This precision 6-Speed Gear Box, High Efficiency, is a compact unit with a variety of gear ratio options to choose from. Several crank arms and a RE-260 motor are included. This versatile, high-efficiency gearbox lets you build one of six different gear ratios so you can select the best combination of speed and torque. Whatever your application, chances are that one of the configurations will do the job. A clutch gear protects the gearbox in high-gear-ratio configurations so that the gearbox doesn't rip itself apart if the output shaft gets stuck.

The 5mm, round output shaft is compatible with the Sports Tire set and Narrow tire set. Perfect for many Tamiya Construction and Robotics projects. Some assembly required.

Gear Ratios: 11.6:1, 29.8:1, 76.5:1, 196.7:1, 505.9:1, and 1300.9:1
can be run safely up to 7.2V

Tamiya 70108 Tracked Vehicle Chassis Kit

The Tracked Vehicle Chassis traverses over objects in its path and rough terrain. Use this kit as a stand-alone or combine it with other accessories making a more complex machine with more capabilities.

Note that the included motor does not allow the treads to move independantly. If you want to control the left and right treads, you should swap out for a Dual Motor Gearbox.

Includes everything you see in the photo- tank tracks, baseplate, motor, gearbox, shafts, etc. (Batteries not included). The gear box can be built with two possible gear ratios–Standard: 203.7:1 or High Speed–58.2:1. Some assembly required.
