2022.1.1551.1 Driven Stepper Motor
- Bob Ebergen
Overview
The Driven Stepper Motor 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 Driven Stepper Motor to an external controller through a Logic Simulator). Adding a Control Panel gives you the option to control the motor from the Unity scene.
Cannot rotated more then 180 degrees in single tick.
A succesfully created Driven Stepper Motor shows up with this gizmo.
Where to find
The Driven Stepper Motor can be found under
Standard Components > Motors > Driven Stepper Motor > Add 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.

|---|---|
Preferred Velocity (deg/s) | Displays the current preferred velocity in degrees per second. |
Target Step | Displays the step the Driven Stepper Motor will rotate to. |
Continuous | Displays whether continuous rotation is enabled (True) or disable (False). |

Wheel Joint | Sets the Wheel Joint the Driven Stepper Motor will control. |
Step Count | Displays the amount of steps in a full rotation. |
Max Velocity (deg/s) | Sets the maximum allowed velocity of the Driven Stepper Motor in degrees per second. |
Acceleration (deg/s/s) | Sets the maximum allowed acceleration of the Driven Stepper Motor in degrees per second per second. |
Zero Offset (deg) | Sets the zero position of the Driven Stepper Motor relative to the zero position of its Wheel Joint. |

Target Gameobject | The gameobject which has a standardcomponent you want the Control Panel for. |
Target Component | The Component which for which a Control Panel is generated. |
How to use
Add a Driven Stepper 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 desired settings.
Press Play to see the rotation of the cube, controlled by the DrivenStepperMotor
