Title:
SYSTEM COMBINED WITH PERMANENT MAGNET EXCITED SYNCHRONOUS MOTOR AND NONCONTACT POWER SUPPLY
Document Type and Number:
Japanese Patent JP3672530
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a system in which a permanent magnet excited synchronous motor and a noncontact power supply are combined.
SOLUTION: This system is provided with a double-sided permanent magnet excited synchronous motor and a noncontact power supply means. The double- sided permanent magnet excited synchronous motor is provided with a stator core, which has air gaps and high-frequency power is applied to, stator coils for the motor which cause the stator core to generate shifting magnetic fields, stator coils for a transformer which wrap both sides of the stator core in its longitudinal direction individually, and a moving element for the motor which moves in the longitudinal direction along the air gaps of the stator core. The noncontact power supply means is provided with a core which corresponds to the secondary core of a transformer, and a coil which is wound on the core by a specified number of times and corresponds to the secondary coil of the transformer.
