Abstract:
An EC motor contains a rotor, a stator, a shaft, a bearing system and an intermediate element connecting the stator to the shaft. The rotor includes a rotor case and one or more permanent magnets, and it is supported, by the bearing system, so as to be rotatable about the shaft. The stator is at least partially arranged, by the intermediate element, in a radially outer circumference of the bearing system. Ideally, a fan contains such an EC motor and a fan wheel connected to the rotor case of the rotor of the EC motor. Moreover, a household appliance contains an EC motor or a fan including the EC motor.
