To provide an efficient control device integrated type motor pump.
The control device integrated type motor pump includes a pump 1, a motor 2 driving the pump 1, a control device 3 controlling the motor 2, and a discharge side pressure measuring instrument 16 measuring fluid pressure on a discharge side of the pump. The control device 3 is mounted to a motor casing of the motor 2. The control device 3 has an inverter 25 generating alternating current power of a frequency which is within a band including a commercial frequency or more, a pump control part 30 generating a torque command value for controlling operation of the pump 1, and a vector control part 40 receiving the torque command value and determining a voltage command value to the inverter 25. The motor 2 has a rotor with a plurality of permanent magnets 20.
