A small motor with a metal gearing with a D-shaped shaft, 3 mm in diameter and approx. 10 mm long. The motor is equipped with an incremental encoder. The recommended operating voltage of the motor is 6 V and at this voltage it achieves a speed of 100 RPM and a maximum torque of 1,4 kg * cm, consuming a current from 0.054 A to 0.59 A.
Recommended supply voltage for motors is 6 V, but the motors operate without problems in the range from 3 V to 9 V. It is possible to supply the motor with higher voltage, but it reduces the service life of the motor.
All N20E motors have the same dimensions. The metal gear housing has two tapped holes for M1.6 bolts (1.6mm diameter, 0.35mm pitch). The engines weigh approx. 14 g.

It is not possible to control the motors directly from the microcontroller ports due to the high power consumption. This problem is solved by the motor drivers. Thanks to the controllers, it is possible not only to turn on and only the motors, but also to control their speed and direction of rotation.
Our offer includes a number of drivers for one or two motors. The drivers are available in the form of modules, shield extensions for Arduino and hat extensions for Raspberry Pi.

Current sensors measure how much current the motors are consuming at a given moment, which allows to determine the load on the motors. Our offer includes sensors with measuring ranges from ± 5 to ± 75.
