Abstract

PURPOSE:To increase the efficiency and torque of an anode motor and shorten and reduce start time by inserting a metal tube between a rotor and a stator core, providing the rotor core in the rotor, and using a hollow axis as the target axis. CONSTITUTION:The rotary part is vacuumized and sealed by fixing one end of the metal tube 10 which is exceedignly thinner than the glass valve 9 between the rotor 6 and the stator core 7 and the lower end of the metal tube 10 to the anode axis 5. The part opposed to the stator core 7 on the tip of the rotor 6 is formed as the rotor core 11 and the secondary conductor 12 is provided on the projection area. In this case, besides the principal gap 14 which is located between the metal tube 10 and the rotor core 11, the auxiliary gap 15 is formed between the rotor core 11 and the anode axis 5. This narrows the gap 14 and the auxiliary gap 15. Since the rotor core 11 is also provided, the permeance of the main magnetic flux increases and the efficiency and torque of a motor can be increased.
