Title:
INDUCTION MOTOR AND LIQUID HYDROGEN PUMP USING THE SAME
Document Type and Number:
Japanese Patent JP2006304488
Kind Code:
A
Abstract:
To provide an induction motor suitable for driving a liquid hydrogen pump.
A resistance is increased by reducing a cross section of a squirrel-cage rotor or using a material having a large resistance for the squirrel-cage rotor. Since a torque is increased during low-speed rotation in an ultracold environment within a liquid hydrogen, the motor is easily activated. An aluminum alloy such as 5000 series, 6000 series, 7000 series is suitable for the material having the large resistance.
