The selection of the gear ratios of the gearbox 70168

Transmission provides a choice of gear ratios, depending on the needs of the project. The user can select one of four options:


Gear ratio

The speed of rotation



1000 rpm

0.4 kg*cm
(0.04 Nm)


320 rpm1.3 kg*cm
(0,12 Nm)
115:1100 rpm4.0 kg*cm
(0.39 Nm)
344:130 rpm12 kg*cm

Control gear Tamiya

For motor control, you can use available in our range modules series DRV8833 or the DRV8835. These systems allow you to power the motors supply voltage of 2.7 V, thereby the mechanical box will retain full viability. The user can also use the controller TB6612, limiting the motor voltage using PWM signal. Drivers can be monitored using sets of line (for example, Arduino, STM32Discovery or minikomputera Rasbperry Pi).


In case of use of own printed circuit BOARDS, we invite you to see the range drivers in the form of chips in housings for soldering surface problems.
