Abstract
A method for manufacturing a stator of a waterproof motor includes disposing a first assembly in a mold where the first assembly includes a coil unit wound around an iron core assembly, and filling the mold with a thermosetting plastic which forms a housing after curing. The housing houses the coil unit and the iron core assembly. A recess is formed at one end of the housing. The method further includes disposing a second assembly in the recess of the housing where the second assembly includes a circuit unit, and filling the recess of the housing with a waterproof glue which envelopes the circuit unit after curing. According to the above, the stator of the waterproof motor is formed.
Claims10
A method for manufacturing a stator of a waterproof motor, comprising:
- disposing a first assembly in a mold, wherein the first assembly includes a coil unit wound around an iron core assembly;
- positioning a second assembly in an electric box, wherein the second assembly includes a circuit unit;
- filling the mold with a thermosetting plastic which forms a housing after curing, wherein the housing envelops the coil unit and the iron core assembly, wherein a recess is formed at one end of the housing, and wherein a retaining ring forms at a circumferential edge of the recess;
- filling the electric box with a waterproof glue which envelops the circuit unit after curing;
- and
- engaging the electric box with the housing to press the retaining ring against the waterproof glue, forming the stator of the waterproof motor.
A stator of a waterproof motor, comprising:
- a first assembly having a coil unit wound around an iron core assembly;
- a second assembly including a circuit unit;
- a housing made of thermosetting plastic and enveloping the coil unit and the iron core assembly, wherein a recess is formed at one end of the housing, and wherein a retaining ring forms at a circumferential edge of the recess;
- and
- an electric box receiving the second assembly and filled with a waterproof glue to envelope the circuit unit with the waterproof glue, wherein the electric box and the housing are coupled with each other, and wherein the retaining ring is pressed against the waterproof glue.
