  • Motor and stator crush resistance device
    Patent number: 10404111
    Abstract: An electric motor can include a stator positioning device. First and second housing bodies can define a motor cavity. The stator can be disposed about the rotor within the motor cavity. The stator positioning device can include a plurality of contact members, and a plurality of cover members. The contact members can cooperate to form an annular contact ring that is coaxial with an output axis and has a first side and a second side. The first side can be in contact with a first end of the stator core. The cover members can cooperate to form an annular cover ring that is coaxial with the axis and coupled to the second side of the contact ring. The cover ring can include a flange that extends radially outward of the contact ring and is axially between the first and second housing bodies to inhibit axial movement of the cover ring.
