Stator, radial flux double-rotor machine and method of manufacture

A Radial flux double-rotor machine comprising:

• a mechanically fixed base;
• a stator according to any of the preceding claims, the carrier device being in positive engagement with the at least one axial end of the winding for torque support and being supported at the base;
• a first rotor arranged radially inside the stator core;
• and
• a second rotor arranged radially outside the stator core.

A method for manufacturing a stator for a radial flux double-rotor machine, comprising the steps of:

• providing a stator core with radially outer stator slots and with radially inner stator slots;
• arranging a carrier device configured for torque support axially offset from the stator core, the carrier device being configured at least in portions as an electrical insulator;
• inserting individual conductor bars through the inner and outer stator slots and through openings or recesses of the carrier device;
• connecting the conductor bars inserted into the inner and outer stator slots at the conductor bar ends to form a winding head, in such a way that the carrier device is arranged between the stator core and the winding head;
• and
• arranging a heat sink which is separate from the carrier device on the winding head.
