The invention discloses a plastic package motor, including a plastic package stator (1), a rotor (2), a rotating shaft (3), and a bearing (4). The rotor (2) is disposed in a cavity (5) of the housing. It further includes at least one end cover, a bearing housing (9) is disposed at the center of the end cover and operates to receive the bearing (4), the bearing (4) operates to support the rotating shaft (3), a flanging (8) axially protruding from an outer edge of the end cover is received in the cavity (5) and fit with inner wall of the cavity (5) whereby implementing radial locating of the end cover, multiple mounting feet (10) protrude from the outer edge of the end cover, multiple connecting parts (11) are disposed on outer end surface of the plastic package stator (1), and the mounting feet (10) are fit with and connected to the connecting parts (11). By way of the flanging extending from the outer edge of the end cover and received in the cavity of the plastic package stator, the bearing housing partially enter the cavity, which affectively reduces the distance between the bearing housings on both ends of the motor, and improves accuracy of concentricity between the rolling bearings in the bearing housing, and stability of the motor product. |
