Title:
METHOD FOR PROCESSING DATA FOR AN ELECTRONICALLY COMMUTATED MOTOR AND MOTOR FOR CARRYING OUT SAID METHOD
Document Type and Number:
WIPO Patent Application WO2003052920
Kind Code:
A8
Abstract:
The invention relates to a method for processing data for an electronically commutated motor, comprising a permanent magnetic rotor, a rotational position sensor, for recording the position of said rotor and a stator with at least one winding branch. A computer of the microprocessor type and a programme which may be executed by said computer are provided for said motor, for carrying out computations. The method involves the following steps: a) the rotor position range in which a current impulse should flow through the at least one winding branch is determined by means of the computer in connection with the programme and the duration (TCurr) of said current impulse determined in repeating steps; b) the time duration (Tpp), dependent on rotational speed is continuously determined, which is necessary for the rotor to pass through a given rotation angular range, c) the ratio of the rotational speed dependent duration (Tpp) and the current impulse duration (Tcurr) is monitored, d) depending on the size of said ratio, at least one given computational operation is carried out in the computer either within (Flag_Fct_Within=1) the duration (TCurr) of a current impulse or in a time period (Flag_Fct_Within=0) outside a current impulse. The invention further relates to a corresponding motor (49).
