Squirrel Cage Rotor

A squirrel cage rotor is the rotating component of an induction motor, designed to convert electromagnetic energy into mechanical motion with a simple, robust construction. It consists of conductive bars embedded in a laminated iron core and connected by end rings; when the stator’s rotating magnetic field cuts across the bars, it induces currents that interact with the field to produce torque. Because the rotor requires no brushes, slip rings, or external electrical connections, squirrel cage motors offer low maintenance, reliable operation, and efficient performance. They are widely used in industrial equipment such as pumps, fans, compressors, conveyors, and machine tools.

The protocol describes how to measure the optomotor response in 13-lined ground squirrels, a cone-dominant species with retinal features resembling the human macula. The platform design enhances handling and reduces anxiety, improving the animal's ability to stay on the raised platform, enabling non-invasive assessment of changes in visual function.

Here we describe how to build a robust spring-transport mechanism for a spinning rotor gauge. This device securely immobilizes the rotor and keeps it under vacuum during transportation. We also describe packaging that minimizes the risk of damage during transport. Tests show our design works for typical shocks during transport.
