Fast and Powerful bots are FUN!

"N20" motors can vary SIGNIFICANTLY in power and speed!

We worked with over a dozen manufacturers to develop the Turnabot N-series motors specifically for small competitive robotics. As far as we are aware, they are the most powerful N10, N20, and N30 motors commercially available in the world! Also, all motors now have their RPM on 2S batteries laser etched on the case!

Price is for 1 (one) motor.

 

Some brushed motor basics:

Torque and stall current have a near linear relationship. Cheap N20s are very weak and have appropriately low stall currents. For comparison on 2S:

Cheap N20 motors (often as low as $4 each) often stall near 0.25 amps and are working hard to move 150g and generally cannot push another 150g around.

Decent N20 motors (usually in the $7-$9 range) often stall near 0.45 amps and while they'll move themselves around fairly well, they are not likely to win many pushing matches.

"Good" N20 motors (usually in the $10-$14 range) generally stall closer to 0.90 amps and have real "authority" with 150g bots and are occasionally used in 1lb bots.

Before we had the Turnabot N20 motors made the "best" N20s we were aware of were rated at 1.60 amps and "appropriately" $18+ in cost.

Turnabot N20 motors stall at an incredible 2.0+ amps on 2S. It is VERY hard to stall these with common insect weight drive systems so using one of them per side on 2.0 amp ESCs has not been a problem. These are NOT rated to run two of them per side on a 2.0 amp ESC, the "standard" Malenki-Nanos for example. That said, while the Malenki-Nano-Integrated-High-Voltage (MNI-HV) is technically rated at 3.5a per channel, testing shows that most run just over 4.0a and are an excellent match for 2 Turnabot N20 motors per side.

Turnabot N10 motors stall at 1.0+ amps on 2S. This 1.0 amp "nominal" is also the appropriate limit for running two of them on ESCs with 2.0 amp max ratings.

 

Please note that even the 3600rpm N10 motors have enough torque that with four of the stickiest tires we're aware of, a 2S lipo at it's minimum suggested voltage (7.4v), and while carrying another 150g bot (300g on the wheels) these will still spin all four tires. The lower rpm motors can spin four sticky tires even in 1lb bots.

This much power in this small of a package means these motors should NOT be stalled for any length of time.

Not all "N20" motors are the same!!! N10 motors are smaller and lighter than N20 motors. Turnabot N10 motors are more powerful than "most" N20 motors.

***We have additional motors that are not listed here in our "standard offerings." If you need any specific Nx0 motor / rpm / power / stall current / voltage, please reach out to us with specifically what you're looking for and we'll see if we have something that will work for you.***
