Description
Technical field
The present invention relates to a kind of motor, especially relate to the direct-drive permanent magnet synchronous motor of a kind of water pump and motor integral.
Background technology
A whole set of water pump system at present most still motor and water pump manufactures respectively, then assembling is integrated, and mostly uses induction type asynchronous machine.The air-cooled technology that the motor that most occasion uses all uses, cooling effect is poor, causes that motor volume is large, efficiency is low more remarkable.General asynchronous machine is determines frequency working method, power output or moment of torsion non-adjustable, immediately use frequency control, also by the narrower impact of speed adjustable range, adjustable range is limited.The water pump system using Induction Motor-Driven is all opened loop control, and the flow that pump exports and pressure are subject to environmental change impact fluctuation comparatively greatly, poor stability.
Summary of the invention
In order to solve in background technology existing technical problem, the present invention proposes a kind of permanent-magnet synchronous direct drive pump motor, mainly solving that motor volume existing for prior art is large, efficiency is low, can not speed governing or speed adjustable range is narrow and the deficiency of output stability difference.
The technology of the present invention solution is: a kind of permanent-magnet synchronous direct drive pump motor, comprises water pump body and motor body, and its special character is: above-mentioned motor body comprises motor housing, is arranged on the power transmission shaft of motor housing inside; Above-mentioned power transmission shaft front end is provided with motor forward flange; Above-mentioned water pump body and power transmission shaft are connected by motor forward flange and are produced and link; Above-mentioned motor housing is also provided with spiral circulation water channel; Above-mentioned spiral circulation water channel comprises the tank matrix being arranged on motor housing rear end and the bosh cover be fixed on tank matrix, and the two forms airtight cyclic water channel jointly; Above-mentioned spiral circulation water channel side and water pump body water side are interconnected, and opposite side and water pump body water inlet end are interconnected;
Above-mentioned power transmission shaft surface is provided with thulium permanent magnet and is fixed by carbon fiber cover;
Above-mentioned transmission the tip of the axis is provided with feedback unit.
Advantage of the present invention is: the present invention have simple and reasonable, be easy to the features such as the manufacturing, especially while the inherent characteristicses such as performance permanent magnet synchronous motor high-performance, stable output, wide speed regulating range, utilize electric-machine directly-driven water pump, motor water cooling but structure system bulk is reduced greatly.
