Abstract
An electric motor for high-temperature applications. The electric motor includes a rotor and a stator with a hollow-cylindrical, ironless stator winding of stoved-enamel wire. Furthermore, a soft-magnetic return is provided which encloses the stator winding. The stator winding is supported by a hollow-cylindrical supporting sleeve lying radially inside against the stator winding.
Claims16
Electric motor for high-temperature applications, comprising:
- a rotor;
- and
- a stator with a hollow-cylindrical, ironless stator winding of a stoved-enamel wire and with a soft-magnetic return enclosing the stator winding,
- wherein the stoved-enamel wire, after it has cured, assures that the stator winding remains dimensionally stable at low temperatures, and
- wherein the stator winding is supported by a hollow-cylindrical supporting sleeve lying radially inside against the stator winding.
