Cooling is predominantly liquid, with forced air cooling for the rotor core.

Induction motors induce an electro-magnetic field into a solid rotor core.

The rotor core is made up of similar laminations as used in the stator core.

Mechanically, the device appears to be an induction motor with a magnetic material placed inside the rotor core.

The major components of a rotor core are: rotor bars, resistance end rings and a shaft.

Rotor sparking may take place during starting and occurs between the rotor bars and rotor core.

The bombe helped to identify the wheel order, the initial positions of the rotor cores, and the stecker partner of a specified letter.

The bombe was designed to discover some of the daily settings of the Enigma machines on the various German military networks: specifically, the set of rotors in use and their positions in the machine; the rotor core start positions for the message-the message key-and one of the wirings of the plugboard.
