摘要： The present invention relates to a method and a system for controlling a permanent magnet excited, brushless, electronically commutated, three-phase electric motor (2) wherein a single-phase main AC voltage (UN) having a mains frequency (fN) is rectified and supplied to an inverter (8) via a slender intermediate circuit (6) containing no, or minimum, intermediate circuit reactance as intermediate circuit voltage (Uz) pulsating at double the mains frequency (2fN) which is actuated for powering and commutating the electric motor (2). Control takes place by means of a field-oriented current-space vector regulator, wherein a q-current (iq) as torque-forming component of the current-space vector (i) is regulated perpendicularly to the permanent magnetic field and a d-current (id) can be regulated as a field-influencing component of the current-space vector (i) in the direction of the permanent magnet field. In this case, dynamic field attenuation occurs, wherein the d-current (id) in the negative range is defined with a sinusoidal profile and at double the main frequency (2fN) and wherein the d-current (id) is regulated according to its phase position and its amplitude such that ripple of the q-current (iq) is minimized. Since the q-current as torque forming component is proportional to the torque, thus the torque ripple is also minimized, in spite of the strongly pulsating intermediate circuit voltage (Uz).

摘要： The present invention relates to a method and a control system for driving a three-strand brushless, electronically commutated electric motor (2), wherein a line AC voltage (UN) is rectified and fed via a slim DC link (8) with minimum DC link reactance as a DC link voltage (UZ) to an inverter (10) that can be driven to supply and commutate the electric motor (2). A pulsating DC voltage (UG) initially generated by rectifying the line AC voltage (UN) is dynamically increased with respect to its instantaneous values by a step-up chopper (18) in such a manner that the resulting DC link voltage (UZ) with a reduced ripple always lies above a defined limit voltage (U18/U1) over time. The control system consists of a network rectifier (6), a downstream slim DC link (8) with minimum DC link reactance and a controllable inverter (10) that can be supplied via the DC link and driven to commutate the electric motor (2). A step-up chopper (18) is integrated therein with a controller (20) designed in such a manner that, the pulsating DC voltage (UG) rectified by the network rectifier (6) is dynamically increased with respect to its instantaneous values in such a manner that the resulting DC link voltage (UZ) with a reduced ripple always lies above a defined limit voltage (U20/U1) over time. Stray inductances (Ls1-Ls3) of the motor winding heads present in the electric motor (2) are used as inductor (L) for the step-up chopper (18).

摘要： In a method and control system for controlling a brushless, electronically commutated electric motor (M), a three-phase source AC voltage (UN) is rectified and fed to a DC link voltage (UZK), which is supplied to an inverter (2) via a slim DC link circuit (6). A motor control unit (10) for PWM pulsing controls the inverter for commutating the electric motor (M) and adjusting the motor speed with a variable duty cycle (A). The duty cycle (A) is influenced by a compensating factor (k) such that the product of the DC link voltage (UZK) and a resulting DC link current (IZK) is kept constant in the link circuit (6). The DC link voltage (UZK) is monitored. When a first threshold value (UZKac.max1) of an AC component (UZKac) is exceeded, the compensating factor (k) is modified to lower the current AC component (UZKac) below the threshold value (UZKac.max1).
