Abstract: A hydraulic tool including an outer rotor electric motor having a rotor and a stator, a hydraulic pump, and a gearbox coupled between the electric motor and the hydraulic pump. In one example, the stator is at least partially received within the rotor. In another example, the electric motor drives the hydraulic pump via the gearbox to pressurize hydraulic fluid within the hydraulic tool.

Abstract: An electric motor may include a rotor assembly including a rotor shaft defining a rotational axis. An electric motor may include a stator assembly including a core, an insulator at least partially covering the core, and a plurality of windings, the insulator defining one of a post that protrudes in an axial direction parallel with the rotational axis or a receptacle in which the post is receivable. An electric motor may include a bus bar assembly including a non-conductive body and a plurality of conductors configured to make an electrical connection between at least two windings of the plurality of windings, the non-conductive body including the other of the post or the receptacle, wherein the receptacle includes at least one of an aperture or a recess, and wherein the post is received within the receptacle to secure the non-conductive body to the insulator.
