These are what your robots have been waiting for. These custom engineered robot drive motors are designed to handle the rigor of combat without breaking, and they won't hurt your wallet either!

• The extra-long 3mm shaft is triple-supported internally so that wheels can be mounted directly.
• All-metal spur gear reduction gearhead mated to a Mabuchi FK-050 motor.
• 9 different gear ratios of 20, 35, 50, 63, 86, 115, 150, 250, and 360:1 available. See product title for actual ratio.
• At only 28grams (0.99oz), these are a lightweight yet powerful motor.

These motors make it super simple to get a robot moving! Just pick up a pair of Snap Wheels wheels and Snap Hubs to mount them, solder on a pair of tinyESCs and your motors are ready to be driven by radio control!  For mounting the motors, use 2-56 screws and our custom motor mounts.  We now also carry 3mm bearing blocks for supporting the shaft in heavy robots or weapon systems.

Specifications

Motor (Mabuchi FK-050SH-13125) Specifications
Operating Voltage: 3V - 18.5V (>10V decreases motor life)

No Load RPM: 11530rpm
No Load Current: 0.09A
Stall Current: 1.3A
Stall Torque: 0.0461kg-cm (0.64oz-in)
Kt: 0.0352kg-cm/A (0.49oz-in/A)

See image above for the motor torque, current, rpm and efficiency curve.
Physical Specifications
Gearbox Length: 11.6mm (0.455in)
Motor Length: 28.7mm (1.13in)
Total Gearmotor Length: 40.3mm (1.59in)
Gearbox Diameter: 15.5mm (0.61in)
Shaft Diameter: 3mm (0.12in) with flat along length
Shaft Length: 38mm (1.5in)
Mounting Holes (2): #2-56 spaced 11mm (0.433in) apart
-do not use screws that protrude more than 4mm (0.156in) into gearbox

Weight (all ratios): 28grams (0.99oz)


Some ratio gearboxes can be interchanged because they use the same pinion gears on the motor.
20, 35, 50, 63: 18T pinions
86, 115, 150, 250: 16T pinions
360: 14T pinion
So (for example) you can remove the 50:1 ratio gearbox from its motor and replace it with a 35:1 ratio gearbox for more speed - without needing to desolder the motor!  (Might want to swap the stickers so you know what's in the robot!)
 

No Load Speed @ Gear Ratio/Voltage



Motors have been tested to work up to 22.2V (6 lipoly cells), but don't expect the motor to run that high forever!
Maximum Torque @ Ratio/Voltage kg-cm



Exceeding 6.84kg-cm (95oz-in) will damage the output gear stage. Do not stall the motors highlighted in red at the indicated voltage.

Hi - are these motor-gears available with encoders? If not, can you recommend an encoder that would be compatible? Thank you.
