Title:
DEVICE INCLUDING AT LEAST ONE AC MOTOR
Document Type and Number:
Japanese Patent JP2017070203
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the protection of a drive control section of an AC motor.SOLUTION: A device (1) includes an AC motor (2), a controller (5), and a power driver (6). Electric energy is supplied to the controller (5) and the power driver (6) by an operating voltage (9) in one case and by a generator voltage (10) of the AC motor (2) in the other case. When the generator voltage (10) is present while the operating voltage (9) is not present, the magnetization of the AC motor (2) is controlled so that the generator voltage (10) is maintained between two limit values, and thereby, sufficient energy for the operation of the controller (5) and the power driver (6) is formed in one case, and an allowable voltage limit value of the power driver (6) is maintained in the other case.SELECTED DRAWING: Figure 1
