Abstract: An inlet part (1) is connected to a trumpet-shaped (4a) or oval vortex chamber with a defined length section geometry and to a vortex concentrator which uses an underpressure to draw the medium from the inlet part into the chamber. A vortex generator for a liquid or gas comprises an inlet part connected to a vortex chamber via a rounded lower connection and to a vortex concentrator via a chamfered lower edge so that the concentrator is inserted into the chamber. The medium in which the vortex is to be generated enters the inlet part, passing at least one wing located in this part, before passing through a rotation symmetrical cavity with a curved geometry and at least one helical cone-shaped channel into a trumpet or oval-shaped vortex chamber. The medium begins to rotate just beneath the soft lower connection on the inlet part and is then forced to flow downwards and swirl around the concentrator. The Coanda effect caused by the medium swirling around the outside of the concentrator acts as a brake and generates an underpressure at this surface, creating a vortex travelling downwards towards the outlet opening in the concentrator. The underpressure sucks the medium toward! s the concentrator surface and into at least one central channel and a channel plate containing at least one channel slanting at angle relative to the concentrator, so that the medium flows through the concentrator towards at least one conical nozzle with at least one vortex channel and at least one outlet opening, leading into the vortex chamber. The length section of the inside (401) of the trumpet-shaped chamber is defined by the function f(x) = k x xy>. k = 8500-9000, y = -1.1 to -1.0, f(x) = x0 to x0 + 250 length units and x0 = 70-170. The length section of the inside of the oval chamber is defined by the function f(x) = k1 x (x2> + k2) x (y2> - C). C = 18-21, k1 = at least 0.003 when x is less than or equal to zero or at least 0.002 when x is greater than zero, and k2 = at least 0.005 when x is less than or equal to zero or at least 0.005 when x is greater than zero.

Inventor: JONSSON RAGNAR GEORG

Abstract: A method and an arrangement for control of an alternating- current induction motor with at least two phases is described. The motor is controlled depending on two control signals S1, S2, which are sent to a vector rotation arrangement 1, whose output signals are used to generate separate drive signals for the motor's phases, wherein a first and a second signal B1, B2, representing the motor's magnetic field, are fed back to the vector rotation arrangement 1 in order to modify the control signals S1, S2. A calculation arrangement 12 calculates a signal Is' corresponding to the inductive current Is through the corresponding stator phase winding 2, determining the magnetic field of the motor, in at least two motor phases, using the formula Is' = E/sL, where E is the magnetisation potential, s is the Laplace operator and L is the inductance of the stator phase winding. The signals Is' calculated for each phase are scaled and utilised as signals representative of the motor's magnetic field. A signal E' representative of the magnetisation potential E can be obtained from a separate measurement winding 20 in the motor's stator. Without having any measurement arrangement on the motor, a signal E' representing the magnetisation potential can be computed from the formula E' = V - RsIo, where V is the power supply voltage, Rs is the resistance of the stator, Io is the power supply current. For low frequencies, an additional signal Is' is computed by approximation, representing the current of the stator phase winding. Both signals computed to represent the current of the stator phase winding go through a high- pass filter and a low-pass filter, respectively, and are then added, so that a signal Is' corresponding to the current of the stator phase winding is available for all frequencies. <IMAGE>
