Definitions

  • a pump according to the invention comprises an electric motor which has a rotor and a stator. Furthermore, the pump comprises a split cage, which separates the area with the rotor, which revolves in the medium being fed and is arranged on a shaft, from the stator. This split cage can be heated.
  • the invention therefore provides for the split cage of the motor of the pump, by means of which the stator of the motor is separated from the moist wet medium being conveyed, to be directly heated in order to thaw out firmly frozen ice or the like between the motor and stator.
  • the capability to heat the split cage means a positive temperature being applied to the split cage by means of an active procedure, which is produced and influenced deliberately.
  • the heating conductors which are arranged on the split cage or integrated therein, to be heatable via the magnetic field of the stator.
  • Encapsulated or printed-o ⁇ electrical heating conductors which are heated via the stator magnetic field can then preferably be switched on and off by means of a switch, in particular a temperature switch.
  • the temperature switch is preferably in the form of a bimetallic element or a PTC element. A heating conductor can then be activated or deactivated as a function of the temperature.
