Abstract
A modular encoder has been developed that can be mounted to a motor shaft without requiring time consuming alignment or special tools. The encoder includes a base having an annular opening, the base including a plurality of resilient arms surrounding the annular opening with each arm having a terminal end that extends into the annular opening, and a hub having a horizontal flange with a top and a bottom surface and a generally vertical wall extending from the bottom surface of the horizontal flange, the wall is configured to fit within the annular opening of the base and is circumscribed with a groove for receiving the terminal ends of the resilient arms to secure the hub to the base and enable rotation of the hub within the annular opening of the base as the terminal ends of the resilient arms slide within the groove.
