Abstract
(EN)
The present invention discloses a counter-rotating motor and a high speed blender, wherein the counter-rotating motor comprises a stator, an inverter, an inner rotor and an outer rotor, the stator is provided with an outer winding and an inner winding, wherein the outer winding and the inner winding have opposite phase sequences; the inverter is connected in parallel with the outer winding and the inner winding to synchronously supply excitation current to the outer winding and the inner winding; the inner rotor is provided in the inner winding and is used for rotating in a first direction under the effect of the inner winding; the outer rotor is provided in the outer winding and is used for rotating in a second direction opposite to the first direction under the effect of the outer winding. The counter-rotating motor of the present invention is provided with two sets of inner and outer matching windings and rotors, and synchronously controls the outer winding and the inner winding through one set of inverters, can save the use of a brush, reduce noise and improve the service life of the motor, meanwhile, because there is no need to use two sets of inverters, the cost is lower and the control is simpler.

La présente invention concerne un moteur contra-rotatif et un mélangeur à grande vitesse, le moteur contra-rotatif comprenant un stator, un onduleur, un rotor interne et un rotor externe, le stator étant pourvu d'un enroulement externe et d'un enroulement interne, et l'enroulement externe et l'enroulement interne ayant des séquences de phase opposées ; l'onduleur est connecté en parallèle à l'enroulement externe et à l'enroulement interne afin de fournir de manière synchrone un courant d'excitation à ces derniers ; le rotor interne est disposé dans l'enroulement interne et est destiné à tourner dans un premier sens sous l'action de l'enroulement interne ; le rotor externe est disposé dans l'enroulement externe et est destiné à tourner dans un second sens opposé au premier sens sous l'action de l'enroulement externe. Le moteur contra-rotatif de la présente invention est pourvu de deux ensembles d'enroulements et de rotors correspondants internes et externes, et commande de manière synchrone l'enroulement externe et l'enroulement interne par l'intermédiaire d'un ensemble d'onduleurs, peut éviter l'utilisation d'une brosse, réduire le bruit et améliorer la durée de vie du moteur, et en même temps, étant donné que l'utilisation de deux ensembles d'onduleurs n'est pas nécessaire, le coût est plus faible et la commande est simplifiée.
