Hermetically Sealed Electric Motor

In these cases the motor is sealed completely within a welded container with the compressor.

Hermetically sealed electric motor.

Ac motors hermetic peerless electric canned motors have made a significant contribution to the ever growing popularity of canned pumps. In hermetically sealed compressor the compressor and the motor are enclosed. The hermetically sealed reciprocating compressor is widely used for the refrigeration and air conditioning applications. In all the household refrigerators deep freezers window air conditioners split air conditioners most of the packaged air conditioners the hermetically sealed reciprocating compressor is used.

A hermetic compressor is disclosed having an electric motor a compressor unit and an overload protector within a hermetically sealed housing. Hermetically sealed enclosure of rotor area obtained without use of static o rings gaskets or epoxy. This type of pump eliminates the nuisance of dynamic shaft seals and stuffing boxes. The hermetically sealed high speed permanent magnet motor module of the upwing subsurface compressor system more and more industries are adopting pm motors over induction motors due to the added value they offer including higher energy density higher efficiency lower heat generation higher speed capabilities and ease of fabrication.

The overload protector includes a thermally activated switching device for selectively providing current to the electric motor a heater element thermally coupled to the switching device and a control circuit controlling the heater element. A good example of a hermetically sealed piece of equipment is a hermetically sealed compressor motor like the ones used in a typical small air conditioning unit for residential or commercial properties.
