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： An electronic control circuit for an electronically commutated motor (ECM) is disclosed. A plurality of power transistors controls the ECM, and a reference transistor is formed together with the power transistors on a common support. A control unit is configured to, in a test mode: apply a test current to the reference transistor and one of the power transistors respectively; measure a saturation voltage of the reference transistor and one of the power transistors; evaluate a saturation voltage difference between the measured saturation voltages of the reference transistor and the respective power transistor; evaluate a rate of change of saturation voltage differences between a first iteration of the test mode and a second iteration of the test mode; and determine an expected remaining service life of the power transistors based on the temperature of the support during the test mode and the rate of change of the saturation voltage differences.

摘要： A brushless dc external-rotor motor having a hollow cylindrical heat sink fastened to the peripheral border region of a printed circuit board. Power semiconductors are arranged on an inner cylinder wall of the heat sink in a heat conducting manner, and the cylinder wall forms part of the peripheral border of the stator flange in the motor. A connector fastens Hall generator(s) on the circuit board and provides the electrical connection with the circuit board. The connector can be soldered along with all other electronic components in a joint soldering process, wherein a subassembly of a preassembled circuit board and a heat sink fastened to its periphery and carrying the power semiconductors passes through a solder bath to solder all components in a single soldering process. It is subsequently necessary only to plug the Hall generator or generators onto the connector or connectors soldered onto the circuit board. The connector can include individual contact tubes, which are soldered in the circuit board and into which the connection pins of a respective Hall generator can be plugged.
