Description
A small motor with a metal gearing with a D-shaped shaft, 3 mm in diameter and approx. 10 mm long. The recommended operating voltage of the motor is 12 V and at this voltage it achieves a speed of 68 RPM and a maximum torque of 1.4 kg * cm, consuming a current from 0.055 A to 0.58 A.
Features
- Motor type: medium power (MP)
- Gear ratio: 200:1
- Supply voltage: 9-15 V
- Speed: 68 RPM
- Maximum torque: 1,4 kg*cm
- Minimum current consumption: 0,055 A
- Maximum current consumption: 0,58 A
Attention!
Overloading the motor can destroy the gearbox or shorten its service life. It is recommended not to exceed the load and 1 kg * cm. Do not block the motor shaft as this may damage the gearbox. It is recommended to supply the motors with a current equal to or less than 25% of the specified maximum current.

It is recommended to supply the motors with a current equal to or less than 25% of the specified maximum current.
Supply voltage
The recommended supply voltage for the motors is 12 V, but the motors operate without problems in the range from 9 V to 15 V. It is possible to supply the motor with higher voltage, but it reduces the service life of the motor.
Dimensions and weight
All N20W engines 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. 15 g.

Motor controllers
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
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.
