Hermetically sealed electric motor.

Hermetically sealed centrifugal compressors hermetically sealed compressors siemens offers two designs of high speed electric motor driven hermetically sealed compressors. 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 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.

These types of compressors are particularly suited for remote unmanned operation and operators focused on minimal weight and space requirements minimal system complexity as. 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 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. Hermetically sealed enclosure of rotor area obtained without use of static o rings gaskets or epoxy.

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. This type of pump eliminates the nuisance of dynamic shaft seals and stuffing boxes.
