Abstract
A fluid pressure unit is provided with an inverter (17), a motor (10) controlled by the inverter, a pump (11) driven by the motor to discharge a fluid, a detector (16) configured to detect a pressure of the fluid, a flow rate of the fluid, or both, a controller (20) configured to control the inverter such that a pressure of the pump, a flow rate of the pump, or both becomes a predetermined value based on a detected value by the detector, and a suppressor (33) configured to suppress a change of an output of the inverter caused by a pulsation frequency component of the fluid included in the detected value.
