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 provides a high-pressure blower comprising a fan arrangement which includes a fan, and a fan housing for conveying working air. An electromotor drives the fan via a motor shaft to provide motor self-ventilation by generating a cooling air stream flowing through the motor due to a cooling wheel driven by the rotor. A wall section separates the interior space of the fan housing accommodating the fan airtight from the interior space of the blower accommodating the electromotor so that the cooling air stream flowing through the electromotor is separated and independent of the air flow of the working air conveyed to the fan.

摘要： A drive circuit for brushless direct-current motors having a cylinder-like air gap between a permanent magnetic inner or outer rotor and a stator, the stator windings being connected to a supply direct-current source in series with a respective feed transistor. The current flux depends on position signals from a semiconductor control element determining the rotor position, in particular a Hall IC, and on the switching state of a semiconductor switch responding to blocking of the rotor and serving as blocking protection for the stator windings. In order to avoid a thermal overload of the stator windings and of the semiconductor elements contained in the circuit, the semiconductor switch provided as the blocking protection is a transistor. The emitter/collector path of the blocking protection transistor is in series with the stator windings and the feed transistors associated with each of these stator windings, and the base of the blocking protection transistor receives an inductive voltage generated in the stator windings.
