Abstract
The utility model discloses an alternating-current permanent magnetism draining pump without a rotor tube. The alternating-current permanent magnetism draining pump comprises a pump cover, a pump body, an impeller assembly in an inner cavity of the pump cover, a stator core in an inner cavity of the pump body, a coil, a magnetic core and a rotor shaft. The alternating-current permanent magnetism draining pump is characterized in that the pump body is a shell surrounding the outer contours of the coil, the stator core and the magnetic core; the shell defines an opening on the top of the shell and a magnetic core containing space which extends to the center of the pump body from the opening and is used for containing the magnetic core; and the two arms of the U-shaped stator core penetrate through the cavity wall of the magnetic core containing space and are placed on the two sides of the magnetic core in a clamping manner, and a rotation gap is remained between the two arms of the U-shaped stator core and the magnetic core. The alternating-current permanent magnetism draining pump provided by the utility model is free of the rotor tube, the distance between the stator core and the magnetic core is reduced, and the outer diameter of the magnetic core can be increased or the inner diameter of the stator core can decrease under the same physical dimension, so that the air gap between the stator core and the magnetic core is narrowed, and the property of the draining pump is improved. As the rotor tube is omitted, the draining pump is more convenient to assemble and maintain.
Description
Technical field
The utility model relates to the permagnetic synchronous motor technical field.
Background technique
U-shaped AC permanent magnet synchronous motor often is applied to draining pump, and therefore this draining pump also often is called the AC permanent-magnet draining pump.This draining pump is mainly used on the washing machine.Because this draining pump has the low voltage starting difficulty, thereby has limited the electromagnetism utilization ratio, makes the whole efficiency of product low.On the other hand, in recent years, along with improving constantly of the aggravation of the increasing of manufacturer, market competition, customer requirement, the cost pressure of this product is also constantly highlighting, and noise problem also needs continuous improvement.
As shown in Figure 1, be the pump shell structure of existing U-shaped AC permanent magnet synchronous motor, this pump comprises a rotor drum 9 ' cylindraceous as seen from the figure, and core assembly is positioned over the rotor drum inner chamber.Rotor drum adopts plastics to make usually, and thickness reaches 1.0mm.Because the existence of rotor drum has increased the air gap between stator iron core and the rotor magnetic core.
The model utility content
The purpose of this utility model is to address the above problem, and a kind of AC permanent-magnet draining pump that promotes pump efficiency, reduces the water pump cost is provided.
In order to reach above-mentioned model utility purpose, the utility model has adopted following technological scheme: the AC permanent-magnet draining pump of cancellation rotor drum, comprise pump cover, the pump housing, be arranged at the impeller assembly of pump cover inner chamber, be arranged at the stator iron core of pump housing inner chamber, coil, magnetic core, rotating shaft, it is characterized in that: the described pump housing is for centering on coil, the housing that the external frame of stator iron core and magnetic core forms, described housing limits one and is opened on the top and extends to the magnetic core containing space that is used for holding magnetic core at pump housing center from opening, U-shaped stator iron core both arms run through magnetic core containing space chamber wall and are folded in the magnetic core both sides, leave running clearance between U-shaped stator iron core both arms and the magnetic core.
Described housing is bottom lock, open-topped semiclosed body.
The described pump housing also is provided with a waterway that is used for accommodating cooling water, and waterway is shaped around the position of U-shaped stator iron core two arms and magnetic core interference, and waterway is opened on the top.Waterway is close to outside the stator iron core, and the heat that stator iron core in the work is produced reaches rapidly the cooling liquid in the waterway, reaches the purpose of motor radiating cooling, effectively reduces the temperature rise of pump motor.
Described magnetic core containing space is provided with rotor bearing in its open top, and described rotor bearing is tightly connected by the open top of bearing sealed ring and magnetic core containing space.
The utility model has been cancelled rotor drum, has dwindled the distance between stator iron core and the magnetic core, under same boundary dimension condition, can increase the external diameter of magnetic core, or reduce the internal diameter of stator iron core, to reduce the air gap between stator iron core and the magnetic core, improves pump performance.Since cancelled rotor drum, also more convenient aspect assembling, maintenance.
