Abstract: A rotor includes a rotor shaft, having a rotation axis; a rotor body, fixed to the rotor shaft and formed of multiple stacked laminations. Magnet mounting grooves are provided in the rotor body, and multiple magnets are disposed in the magnet mounting grooves, with a gap formed between each magnet and an inner wall of the corresponding magnet mounting grooves. First and second end plates are respectively disposed at two ends of the rotor body along the rotation axis. A fluid cooling system includes a slot, disposed on one of the first end plate and second end plate, and located on a side of this end plate that faces towards the rotor body; a through-hole, disposed on the other of the first end plate and second end plate; and the gap. The slot, the gap and the through-hole are in fluid communication to form a cooling medium channel.

Abstract: A motor component, a motor and a motor vehicle are disclosed. The motor component has a body extending along a rotation axis of the motor, the body being formed by a set of laminations, and an axially extending cavity being provided on the body; and wherein at least one elongated lamination-holding component is provided in the body, and the lamination-holding component is inserted into the axially extending cavity and is coupled to the body inside the axially extending cavity.

Abstract: A rotor lock assembly for locking a rotor of a wind turbine includes at least one removable rotor lock. The removable rotor lock has a housing comprising an opening and a mounting portion, a pin shaft positioned within the opening, and a locking mechanism. The opening extends from a first end to a second end thereof. The mounting portion is adapted for mounting to a bearing housing adjacent to a rotor lock plate of the rotor.
