# High Speed DC Motor

![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/130motor_1.png)

This is a DC motor compatible with Lego technic parts, the speed is 2 times more than the 9g motor. The output axle is also compatible with Lego technic axles. It is suitable for driving robots that require a high speed for example in racing scenarios.

### Specifications

* Operating Voltage: 3.3V\~6V
* Rated Voltage: 4.8V
* Rated Current: 200mA
* Blocked Rotor Current: 1800mA
* Maximum RPM: 200rpm
* Stopping Torque: 1000g
* Weight: 44g
* Connector: Red and Black Motor Connector

### Special Features:

* Uses an axle connector for output:
  * Connect to axles of different lengths to better suit your needs
* Dual outputs:
  * Has outputs axles on both sides
* High speed
  * About 3 times the RPM of the GeekServo 9g Motor
* Carbon Brushed Motor
  * Longer Lifespan and Lower Noise

### Dimensions

#### In Lego units:

* Length: 10
* Width: 5
* Height: 3
* Output Axle: Technic Axle

#### In mm units:

* Length: 72mm
* Width: 39mm
* Height: 23.8mm
* Output Axle: Technic Axle

### Connection

In this demonstration, Robotbit is used. It is also possible to use an Armourbit.

#### Robotbit

***

Connect the cable to the motor.

```
Reversing the connection would not damage the motor, but the rotational direction will be reversed.

### FAQ

1: The Micro:bit does not react when I click the programming blocks.

Make sure the Micro:bit has been connected to the Kittenblock and then try flashing the firmware.
