Biollante Linear Actuator
The motor is an Eastern Air Devices linear actuator, basically a stepper with threads going all the way through instead of a solid shaft. If the matching threaded rod isn't held still it'll just spin and look silly, so a square shaft matches a square hole in a metal plate bolted to the front to prevent this.

That motion is about 7,000 half-steps.
