The invention is applicable to the field of motors, and discloses a motor bearing anti-corrosion structure and a brushless DC motor. The motor bearing anti-corrosion structure includes a stator iron core, a conductive locking piece, a conductive nut assembly, a plastic-encapsulated casing and a cover fixed to the plastic-encapsulated casing. The first end cover at one end, the conductive nut assembly and the stator iron core are packaged and fixed in the plastic casing, and one end of the conductive nut assembly is connected with the stator iron core, and the other end is exposed outside the plastic casing. One end of the conductive locking piece is clamped outside the through hole, the other end passes through the through hole, and is screwed to the end of the conductive nut assembly exposed outside the plastic casing. The present invention realizes the conductive connection between the stator iron core and the first end cover through the cooperation of the conductive locking member and the conductive nut assembly, effectively preventing the occurrence of electrical corrosion of the bearing; The long-term reliability of the end cover conduction ensures the long-term effectiveness of the motor's anti-corrosion structure of the bearing.

The invention is suitable for the field of a motor and discloses a motor wire outgoing seat and a motor for a clothes dryer. The motor wire outgoing seat comprises a substrate with a wire groove and an elastic buckle structure which is disposed on the substrate and used to be in buckle connection with a motor end cover; the substrate is provided with a first plate face, a second plate face, a first side edge and a second side edge, the first plate face and the second plate face are oppositely disposed, and the first side edge and the second side edge are oppositely disposed; the elastic buckle structure is disposed on the first plate face in a protruding manner; and a wire groove is disposed in a penetrating manner facing the second plate face from the first plate face, and the wire groove is provide with a mounting groove mouth which penetrates the first side edge and which is used for a power line to be clamped into and mounted. In the invention, the motor wire outgoing seat is buckled to and installed on the motor end cover, is convenient to install, and is in favor of achieving automatic assembling of the motor wire outgoing seat on the motor end cover and guaranteeing installation stability and reliability of the motor wire outgoing seat on the motor end cover; and the power line of the wire outgoing groove is clamped into the wire groove from the mounting groove mouth, assembling of the wire outgoing groove is simple, automatic assembling between the power line and the wire outgoing groove is facilitated to be achieved, and wire outgoing assembling operation efficiency of the motor is improved.

The invention relates to the field of motors, and discloses a plastic package stator and bearing end cap waterproof sealing structure and a plastic package motor. The plastic package stator and bearing end cap waterproof sealing structure comprises a plastic package stator, a bearing end cap and a waterproof sealing ring between the plastic package stator and the bearing end cap, wherein the plastic package stator is provided with an annular clamping flange, the bearing end cap is provided with an annular clamping groove matched with the annular clamping flange in a clamped and inserted mode, the annular clamping flange is provided with an axial end face towards the bearing end cap in the axial direction of the plastic package stator, the annular clamping groove is provided with a bottom groove towards the plastic package stator in the axial direction of the plastic package stator, the waterproof sealing ring is elastically compressed between the axial end face and the bottom groove face, and a positioning hole allowing the waterproof sealing ring to be clamped and positioned is formed in the bottom groove face in a concave mode. The plastic package stator and bearing end cap waterproof sealing structure prevents influences of a needle insertion hole, a detection hole and a detachment notch which probably exist in the radial outer surface of the annular clamping flange on the sealing effect of the waterproof sealing ring, and achieves the aims of improving the waterproof sealing effect between the plastic package stator and the bearing end cap.
