Title:
ELECTRIC MOTOR OF SHIELD PUMP
Document Type and Number:
WIPO Patent Application WO/2022/253269
Kind Code:
A1
Abstract:
An electric motor of a shield pump, which relates to the technical field of shield pumps. The electric motor comprises an electric motor cylinder, which is internally provided with a rotor assembly and a stator assembly, which is connected to the rotor assembly in a sleeved manner, wherein the rotor assembly is connected to a shield cover in a sleeved manner, the shield cover is a carbon fiber shield cover, and the rotor assembly has a rotational speed of no less than 10000 r/min. By means of the present application, a rotor shaft with a rotational speed of no less than 10000 r/min is used to drive the rotor assembly to operate, and the shield cover has a corresponding thickness, and matches with the rotor shaft with a rotational speed of not less than 10000 r/min to achieve an effective combination, and achieves the effect of a maximum efficiency of more than 90%.
