Claims7
A system for insulating an electric motor stator for a pump with resin, the system comprising:
- a resin fixture for placement with the stator's bore, the resin fixture comprising:
- a tube comprising longitudinally spaced holes;
- a first plug at a first end of the tube;
- a second plug at a second end of the tube, the second plug including a valve;
- and
- a rubber cover over the tube;
- a first end plug at a first end of the stator and a second end plug at a second end of the stator;
- an outer cover around the stator and between the end plugs;
- a first inner spacer ring at the first end of the stator and a second inner spacer ring at the second end of the stator, the inner spacer rings being placed between lead wires of the stator and the resin fixture adjacent the first and second end plugs;
- and
- a first outer spacer ring at the first end of the stator and a second outer spacer ring at the second end of the stator, the outer spacer rings being placed between lead wires of the stator and the outer cover adjacent the first and second end plugs.
