Abstract
A method of producing an electric motor which can prevent resin from ending up leaking from an opening for lead wire use when performing a step of filling a resin in the internal space of the electric motor, provided with a step of attaching a bracket which has an opening for leading lead wires of a coil to the outside, a step of arranging a seal member which has through holes which hold the lead wires at the opening so as to tightly contact without clearance the wall surfaces which define the opening while passing the lead wires through the through holes, and a step of filling a resin in the internal space which is defined by the bracket and the stator core.

A method of producing a stator of an electric motor comprising:
- attaching a bracket to a stator core around which a coil is wound, the bracket including an opening for leading out a lead wire of the coil;
- arranging a seal member in the opening so that the seal member tightly contacts a wall surface defining the opening without clearance, the seal member including a through hole for receiving the lead wire, the lead wire being inserted into the through hole;
- and
- filling a resin in the internal space defined by the bracket and the stator core.
A stator comprising:
- a stator core around which a coil is wound;
- a bracket attached to the stator core and having an opening for leading out a lead wire of the coil;
- a seal member arranged in the opening so as to tightly contact a wall surface defining the opening without clearance, and including a through hole for receiving the lead wire;
- and
- a resin arranged in an internal space defined by the bracket and the stator core.
