REGULATOR CIRCUIT FOR AN ELECTRIC MOTOR, PROVIDED WITH A MICROPROCESSOR

摘要

The invention relates to a regulator circuit for controlling the power fed to an electric motor from a voltage source, wherein the regulator circuit comprises a semiconductor switching element connected in series to the electric motor and the voltage source for the purpose of controlling the power fed to the electric motor, a control circuit for controlling the semiconductor switching element, and a first operating element for operating the control circuit by means of an operating signal generated by the operating element and fed to the control circuit, wherein a microprocessor is incorporated in the control circuit. The microprocessor can be adapted to control numerous functions within the regulator circuit, in particular monitoring and safety functions. It is however also possible for the microprocessor to be adapted to control the power fed to the electric motor subject to the operating signal. This can relate to performing of this single function as well as to performing this function in combination with safety functions.
