An electric motor with a heat source is arranged on a shaft in a co-rotating manner, wherein a first and a second cooling fin arrangement interact in order to dissipate heat from the heat source to the outside.

Electric motor with rotating first concentric cooling fins and second concentric fins on the housing

A drive system includes a three-phase motor having a shaft, a first three-phase stator winding which is to be connected to a three-phase AC voltage grid, a second three-phase stator winding which is to be connected to the three-phase AC voltage grid in such a way that a second stator rotating field rotating in opposition results with respect to a first stator rotating field which is generated by means of the first stator winding, and a rotor winding system which is mechanically coupled in a rotationally fixed manner to the shaft. The drive system further includes at least one inverter which is mechanically coupled in a rotationally fixed manner to the shaft and which is electrically coupled to the rotor winding system, wherein the at least one inverter is configured to generate actuation signals for the rotor winding system such that a first rotor rotating field and a second rotor rotating field rotating in opposition to the first rotor rotating field are generated. The at least one inverter is configured to generate the actuation signals for the rotor winding system solely depending on signals detected on the rotor side.

Method for operating a drive system, and drive system

A drive system includes a three-phase motor having a shaft, a first three-phase stator winding, which is to be connected to a three-phase AC voltage grid, a second three-phase stator winding, which is to be connected to the three-phase AC voltage grid in such a way that a second stator rotating field is produced rotating in opposition with respect to a first stator rotating field, which is generated by the first stator winding, and a rotor winding system which is mechanically coupled in rotationally fixed fashion to the shaft. The drive system further includes at least one inverter, which is mechanically coupled in rotationally fixed fashion to the shaft and which is electrically coupled to the rotor winding system, wherein the at least one inverter is designed to generate actuation signals for the rotor winding system in such a way that a first rotor rotating field and a second rotor rotating field are generated, wherein the first rotor rotating field interacts with the first stator rotating field in such a way that a first motor speed and a first torque are produced, and wherein the second rotor rotating field interacts with the second stator rotating field in such a way that the first motor speed and a second torque are produced, wherein the second torque has an identical direction of action with respect to the first torque.

Drive system

A drive system has an electric motor having a shaft; an electronic assembly; and a fan driven by way of the shaft, the electronic assembly being rigidly and thermally coupled to the fan.

A drive system has: a three-phase motor, having: a shaft, a first three-phase winding set, having: a three-phase stator winding for connection to a three-phase alternating voltage network and a three-phase rotor winding, which is coupled to the shaft in a mechanical, rotationally fixed manner, a second three-phase winding set, having: a three-phase stator winding for connection to the three-phase alternating voltage network in such a manner that rotary field is produced that runs in the opposite direction to a rotary field that is produced by the stator winding of the first winding set.
