Plastic shell motor

Abstract

The invention discloses a plastic shell motor, which comprises a stator assembly (1), a rotor assembly (2), a control circuit board (3), bearings (4), a rotating shaft (5), a front end cover (6) and a rear end cover (7), wherein the front end cover (6) and the rear end cover (7) are assembled together to form a plurality of accommodating cavities; a bearing cavity (61) is formed at the top of the front end cover (6); a stator accommodating cavity (62) is formed below the bearing cavity (61) of the front end cover (6); a circuit board accommodating cavity (72) is formed below the stator accommodating cavity (62) and inside the rear end cover (7); a bearing cavity (71) is formed below the circuit board accommodating cavity (72) and at the bottom of the rear end cover (7); the bearings (4) are arranged inside the bearing cavities (61, 71); the stator assembly (1) is nested inside the stator accommodating cavity (62); and the control circuit board (3) is arranged inside the circuit board accommodating cavity (72). The plastic shell motor has the advantages of good reclaimable property, environmental protection, strong universality, convenient and reliable assembly and the like, and is suitable for a single-phase brushless motor and a three-phase brushless motor.

Description

Technical field: [0001] The invention relates to a plastic casing motor. Background technique: [0002] At present, plastic-encapsulated motors have disadvantages such as poor recyclability, high recycling cost, not environmental protection, and poor versatility.
