Motorsystem eines Fahrzeuges vom Typ elektrisch |
摘要 |
The invention relates to a motor system of an electric vehicle comprising at least two asynchronous electric motors (M1, M2) supplied in parallel from a central electrical supply (2). This central electrical supply is managed by a control device (6) which provides it with a first control signal (SCF) determining the value of the supply frequency (FAL) and a second control signal (SCA) determining the value of the supply amplitude (UAL) of the supply voltage. These first and second control signals are adjusted essentially as a function of a signal (SMI) measuring the main supply current (IAL), a desired signal (SCS) and a signal (SFMX) representing the value of the maximum frequency of rotation of the rotors (R1, R2) belonging to the said motors. <IMAGE> |
