HYDRAULIC UNIT AND METHOD OF CONTROLLING SPEED OF MOTOR IN HYDRAULIC UNIT |
摘要 |
<p>In the present invention, an oil pressure unit includes an inverter 14 for supplying electric power to a motor 15; a load sensor 17 for detecting a load of the oil pressure pump 16A; a rotation sensor 19 for detecting a rotation speed of the motor 15; a current command value calculation means 12 for calculating a current command value so that a deviation between a speed command value representing a target rotation speed of the motor 15 and a rotation speed of the motor 15 converges to zero; a correction means 18A for correcting the current command value based on the load of the oil pressure pump 16A; and a control signal generation means for outputting a control signal to the inverter 14 based on a corrected current command value.</p> |
