Title: PUMP DEVICE AND METHOD FOR CONTROLLING PUMP DEVICE
Abstract:
This pump device has a pump unit having an electric motor, and a control device. The control device has a drive circuit unit that energizes the electric motor, and a control unit that controls the drive circuit unit. The pump unit and/or the control device has a detection unit that detects a physical quantity pertaining to the load of the electric motor. The control unit determines whether there are any abnormalities on the basis of the physical quantity detected by the detection unit, controls the drive circuit unit in a normal control mode when conditions are determined to be normal, and controls the drive circuit unit in an abnormal control mode when conditions are determined to be abnormal.
