Title:
ロータコアの加熱装置
Document Type and Number:
Japanese Patent JP6801394
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heating device of a rotor core capable of further shortening heat-up time.SOLUTION: Disclosed is a heating device 100 of a rotor core 200, which heats the rotor core 200 by supplying a current to the inner peripheral side coil 1 arranged in the inner peripheral side of the rotor core 200 formed in a hollow cylindrical shape and the outer peripheral side coil 2 arranged in the outer peripheral side of the rotor core 200. This device includes: temperature monitoring means 5 for monitoring the temperature on the inner peripheral surface of the rotor core 200 and the temperature on the outer peripheral surface of the rotor core 200; and a change-over switch 4 for switching between current supply to the inner peripheral side coil 1 and the current supply to the outer peripheral side coil 2 based on the temperature of the inner peripheral surface and the temperature of the outer peripheral surface monitored by the temperature monitoring means 5.SELECTED DRAWING: Figure 1
