PROBLEM TO BE SOLVED: To provide an electric oil pump having a structure with which contaminants in lubricating oil can be removed without forming a new compartment or passage.SOLUTION: An electric oil pump 1 is equipped with a pump unit 10, a rotary shaft 15 that transmits driving force to the pump unit 10, a rotor housing 42 affixed to the end of the rotary shaft 15 opposite the pump unit 10, and magnets 43 affixed within the rotor housing 42. The rotor housing 42 is formed by stacking multiple first electromagnetic steel plates and multiple second electromagnetic steel plates, with the first electromagnetic steel plates having multiple first holes 44 into which magnets 43 can be inserted, and the second electromagnetic steel plates having multiple second holes 45 having a larger opening area than that of the first holes 44. The magnets 43 can be inserted with the first electromagnetic steel plates and the second electromagnetic steel plates having been stacked together, and the multiple second electromagnetic steel plates are stacked continuously at one or both ends of the rotor housing 42. |
