45mm planetory gearbox motor 10/45/100/300 rpm
In stock
If you are searching for a motor with very high torque then this Planetary Gear DC motor – 10 RPM / 12V will fulfill your specification demands.
This Planetary Gear DC motor has the massive torque of 23 kg-cm at no load.
The planetary geared motors are always well known for their low backlash and higher efficiency characteristic to meet the higher expectation.
As these Epicyclic Gear Train motors are very popular amongst our Robotics designer.
So we must ensure them for the quality and performance of these motors.
For that purpose when we receive these Planetary DC Geared Motor, we get them out and start testing each motor in our lab for the extreme pushable limits they can withstand.
This is 12V DC motor which has a gearbox of 45mm diameter.

In stock
An antenna is a device to transmit and receive electromagnetic waves. Electromagnetic waves are often referred to as radio waves. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction. Here you can get an antenna for UBlox NEO GPS model, Antenna Base Set and many more GPS modules.
