Dual shaft TT motor 1:120 robot yellow DC Gear Motor 5V 90RPM Smart Car


Perhaps you've been assembling a new robot friend, adding a computer for a brain and other fun personality touches. Now the time has come to let it leave the nest and fly on its own wings– err, wheels! 


These durable (but affordable!) plastic gearbox motors (also known as 'TT' motors) are an easy, low-cost way to get your projects moving. This is a TT DC Gearbox Motor with a gear ratio of 1:120 to increase torque and speed is slow about 100RPM on 5V, Since gear ratio is 1:120, As a result, they have more torque but a slower rotational speed.


You can power these motors with 3VDC up to 6VDC, they'll of course go a little faster at the higher voltages. We grabbed one motor and found these stats when running it from a bench-top supply


Voltage, RPM and torque
Suitable voltage is 4V to 6V given below are some results on other voltages
3V: 40RPM 0.45kgf.cm
5V: 90RPM 0.65kgf.cm
7.4V: 110RPM 0.85kgf.cm
9V: 140RPM 0.95kgf.cm


Working Voltage: 3V to 6V (7.4V and 9V can be given for short time)
Double shaft, The wheel can be attached to both sides of the motor
Gear ratio: 1:120
Motor Size: 70 x 36.5 x 24.5mm (L*W*H)
