Title:
CONTROL DEVICE FOR ELECTRICALLY-DRIVEN COMPRESSOR
Document Type and Number:
Japanese Patent JP2015186318
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for an electrically-driven compressor capable of suppressing power consumption without requiring a large memory capacity.SOLUTION: A control device for a vane rotary type electrically-driven compressor including a rotor that is rotated and driven by a motor 2 includes: a motor driving section 5 for generating a motor drive signal; and a motor drive control device 4 for generating a control signal of the motor driving section. The motor drive control device includes: a memory 11 storing a table associating a stop command angle representing an angle of the rotor in the case where a stop command of the motor is outputted, an estimated stop angle indicating an estimated stop angle of the rotor and a current phase command instructing such a current phase that a difference from the estimated stop angle becomes a predetermined value; and a control section 12 which estimates a stop position of the rotor by acquiring from the table the estimated stop angle corresponding to the stop command angle on the basis of the motor drive signal, acquires from the table the current phase command corresponding to the stop position, generates such a control signal that maximum torque of the motor is outputted, and supplies the control signal to the motor driving section.
