Title:
MOTOR DRIVER
Document Type and Number:
Japanese Patent JP2001169577
Kind Code:
A
Abstract:
To suppress heating by suppressing the slip in a motor.
An inverter controller 4 enhances the output frequency of an inverter 3 while enhancing the output voltage of the inverter 3 when the motor 1 is accelerated. The controller 4 controls to decelerate the speed for enhancing the output frequency of the inverter 3, with the case that the output voltage of the inverter 3 becomes a rated voltage to maintain the output voltage of the inverter 3 constant as a reference.
