Title:
HIGH PRESSURE CLEANING DEVICE, AND A METHOD FOR VARYING THE MOTOR POWER THEREOF
Document Type and Number:
WIPO Patent Application WO2008064759
Kind Code:
A8
Abstract:
The invention relates to a high pressure cleaning device with an electric motor and a pump driven by said electric motor for the delivery of pressurized cleaning fluid, wherein the electric motor contains a coil mechanism with at least one coil for the production of a magnetic field, and the electric motor is connected to a control unit for controlling the motor power. In order to develop the high pressure cleaning device further in such a way that the motor power can be easily constructively altered also for motors of greater power without creating network reactions that are not tolerable, it is proposed according to the present invention that the number of the effective turns of the coil mechanism for the creation of a magnetic field can be changed by the control mechanism. Further, a method is proposed for changing the power of the electric motor for a high pressure cleaning device of this kind.
