AC stepless variable power automatic speed-regulating motor

Abstract

The invention provides a kind of high efficient alternate infinitive power speed adaptation electric engine which outputs power according to the rotational speed cube, which is made up of engine shell, stator iron core, stator winding, inductive rotor, shaft adjusting mechanism of rotor iron core shaft and end cap. The iron core of the inductive rotor is made up of two laminations containing slot whose length ratio is from 1:2 to 1:4, the long iron core is the torque output iron core, the short iron core is slip power feedback iron core. The windings of the inductive rotor is made up of several independent coil which constitutes loop by themselves and they are insulated from each other used by the long and short iron core, each coil reverses the phase between the two iron cores and changes the pitch. The electric engine applies to fan, pump speed adjustment, the structure is simple, the price is low, and the efficiency is high.

Description

Technical field [0001] The invention relates to an AC speed-regulating motor, especially an AC stepless variable power self-adjusting motor suitable for power-saving operation of fans and water pumps. Background technique [0002] Among the AC stepless speed regulation systems in the prior art, only cascade speed regulation and frequency conversion speed regulation are highly efficient, but these speed regulation systems with additional devices have complicated technology, high price and various negative effects. For example: the high-order harmonics of the electronic speed control device not only pollute the power grid, but also pollute the motor; the power factor of the cascade speed control system is only about 0.55. [0003] Among the many patents of AC stepless self-adjusting motors disclosed, the prototypes developed by various technical solutions have not yet reached the level of replacing the electromagnetic speed-adjusting motors with energy-consuming speed regulati...
