Abstract
A drive device with radiofrequency control includes a motor, a radiofrequency receiver for receiving radiofrequency signals and for controlling the motor. Electrical conductors provide power for both the motor and the radiofrequency circuit. The antenna is connected to the radiofrequency receiver and is non-galvanically electrically coupled one of the conductors at radiofrequencies. The control circuit receives radiofrequency signals directly through the antenna or via radiofrequency coupling from one of the power supply conductors. The device has increased ability to receive radiofrequency signals independent of its environment.
