摘要： The present invention provides an acceleration method for V/f controlled induction motor in flux-weakening region, which comprises: acquiring no-load magnetizing current Im of the induction motor at current stator frequency; selecting a smaller one of 0.5·Im(1/σ+1) and (Im2+σ)/(Im+σIm) as magnetizing current set point, in which σ is an estimated total leakage inductance coefficient; getting an error signal by subtracting the magnetizing current of the induction motor from the magnetizing current set point; determining the stator frequency for the next control period according to the error signal which is provided as a controlling variable of negative feedback. The acceleration method of the present invention can provide the maximum output torque in flux-weakening region and has a larger tolerance for the error of the estimated leakage inductance.

摘要： The invention concerns the electric asynchronous engines including a rotor as a flat disc, and a stator, which is coaxial to the rotor, and is installed with a working backlash relative to the rotor's disk. The stator includes three laminated packages of cores with phase coils, which are situated around the shaft of the motor under 120° angle, one in relation to other. The cores' packages are enclosed between the first and the second flat base plates, which are executed from nonconductive material, and the planes of the base plates are perpendicular to the axis of the shaft. The cores are executed as rectilinear laminated packages, and their axes are parallel to the shaft's axis. The second base plate is identical to the first one, and the butt-ends of the other side of the cores' packages are fixed in it. The invention is presented in three variants, where different fulfillments of the motor are shown: with a sectioned stator, with a sectioned rotor or with the stator and the rotor both sectioned.
