Control device for a synchronous motor for controlling a synchronous motor when performing an energy recovery operation and for stopping the synchronous motor in case of failure of the power supply
Control device for a synchronous motor for controlling a synchronous motor when performing an energy recovery operation and for stopping the synchronous motor in case of failure of the power supply
A second current command value for the q-axis, which is preset by a q-axis current command value presetting unit when an ac power source fails during operation of a synchronous motor, and a second d-axis current command value supplied by a presetting unit for The current command value for the d-axis is preset when the ac power source fails during operation of the synchronous motor are set so that the absolute value of the power consumption of the synchronous motor per unit time is equal to the loss of the synchronous motor per unit time.
