Motor Component

This section documents the configuration attributes for each built-in motor model. Use these pages when you are writing a JSON configuration, debugging a config validation error, or looking up the default for a specific attribute.

For how to add and configure a motor component on your machine, see Motor.
For the methods you call on a motor in code, see the Motor API reference.
For motor models outside the built-in set, search for motor in the Viam registry. Each registry module’s configuration is documented in its own README on its registry page.
