Device for Transmitting Power through Rotating Magnetic Fields

A device for transmitting power using rotating magnetic fields comprising:

• a drive shaft;
• an external magnet fitted on said drive shaft;
• a pump shaft;
• an internal magnet fitted on said pump shaft and configured to be entrained by said external magnet;
• and
• a rear tight chamber or rear containment body for said pump shaft and said internal magnet,
• wherein said containment body comprises a cup-shaped casing positioned between said internal magnet and said external magnet,
• wherein said rear tight chamber or rear containment body comprises a first tight cup-shaped casing forming an external cup-shaped casing having a structural function, and a second cup-shaped casing forming an internal cup-shaped casing housed in said external cup-shaped casing configured to come directly into contact with a pumped fluid, and
• wherein said rear tight chamber or rear containment body further comprises a temperature sensor or probe comprising a miniaturized thermocouple integrated into a thickness of said cup-shaped casing and located in a magnetic field between said external magnet and said internal magnet.
