2021.1.1124.2 DC Motor.
- Bob Ebergen
Overview
The DCMotor is a component to simulate an accelerated rotational motion on an axis. It consists of two components; Physical and Logic. Both are needed to control the motor through a logic adapter (connecting the DCMotor to an external controller through a Logic Simulator). Adding a Control Panel gives you the option to control the motor from the Unity scene.
A succesfully created DCMotor shows up with this gizmo.
Where to find
The DC Motor can be found under
Standard Components > Motors > DC Motor > Physical Component
It will automatically be attached to a selected GameObject. Otherwise it will create a new GameObject to attach to.
A WheelJoint will be created automatically as part of the component.
Selecting the newly created GameObject shows you the following menu in the Inspector.
Please note: this is an example of a GameObject with the Physical DCMotor component.

DCMotor Properties |
|
Preferred Velocity (deg/s) | Sets the desired velocity at which the DCMotor should spin. |
Velocity (deg/s) | Displays current velocity in degrees per second. |
Start/Stop | Starts/Stops the motor. |

How to use
Add a DC Motor Component to a GameObject, in this case a simple cube.
Add a Kinematics Controller, this can be found under Mechanics > Kinematics > Add Kinematics Controller. Make sure the Cube is parented under the Kinematic Controller in the Hierarchy.
Add a Control Panel and set the Preferred Velocity
Press Play to see the rotation of the cube, controlled by the DC Motor
