  • Motor drive particularly for submersed electric pumps
    Patent number: 8680729
    Abstract: A motor drive, particularly for submersed electric pumps, has a jacket closed hermetically by a bottom and a head in order to form a first hermetic chamber, which contains an electric motor that is immersed in a bath of dielectric cooling liquid; the jacket is associated with an enclosure in order to form a second hermetic chamber, which contains a power supply and control unit connected to the electric motor. The motor drive includes a compensation means that balances the variations in volume of the dielectric cooling liquid and generates an overpressure within the first hermetic chamber, the first hermetic chamber is substantially independent of the second hermetic chamber.
