Abstract

The utility model relates to a float motor, mainly comprising a stator, a rotor winding, an end cover, and a waterproof casing, wherein, the end cover is provided with ventilative holes and ventilative windows. The end cover which supports a bearing chamber is made into a frame-shaped, which saves material. A suspension water pump is formed by that the float motor drives a water pump, which can reduce the temperature rising of the motor. The suspension water pump has the advantages of low cost, long service life, and fixed assembly dimension.

Description

Float motor

The utility model relates to motor, particularly a kind of motor of working in the liquid that floats over.

Common motor all can not float in the liquid and work, and also has the bucker that adds sealing at common electric machine to form air chamber, motor is floated in the liquid work, and drive the motor of machine work such as water pump, as my motor of patent float electric pump.The shell of this motor has stopped heat radiation, causes defectives such as temperature rise height.

The purpose of this utility model is that a kind of motor of design has floating motor bucker and that have good heat radiating to ventilate outward.

Floating motor of the present utility model mainly contains stator, rotor winding, and the shell of end cap and waterproof is formed, and has the hole or the window of ventilation at end cap.Make the interior temperature of motor be substantially equal to the interior temperature of shell of waterproof, because the floating motor generally all is erectly to float in the liquid to work, the bottom radiating condition is better, and whether the ventilation hole of bottom end cover needs, and can decide according to technology.

The floating motor that the utility model is designed; its end cap can be made into the shelf type; bearing chamber propped up get final product; saved material widely; because the protection of shell does not need to do very firmly; and the shell of stator also can do very thinly or not need shell, and allows end cap directly be enclosed within on the silicon steel sheet of stator.Help the also material saving of dispelling the heat like this, reduce cost.With this driven by motor water pump, form floated water pump, electric machine temperature rise is reduced, cost reduces, and the life-span prolongs, and fitted position can change.

Fig. 1 is a floating motor schematic diagram.

Describe embodiment in detail below in conjunction with Fig. 1.

Constitute a seal as figure floating motor by case 7 and fixed head 8 sealing butt joints, motor body is made up of upper and lower end cap 3, stator 6 and rotor etc., stator is without shell or thin outer crust very, end cap can be made into the shelf type, as long as there are several supports that bearing Room 10 are propped up, has both economized material, ventilate again, also can make the interior temperature of seal even, favourable heat radiation at rotation place dress fan 2.Rotor axis of electric 1, winding 4, pull bar 5, mechanical seal chamber 9.

Claims

A kind of floating motor, the shell that mainly contains stator, rotor winding, end cap and waterproof is formed, and it is characterized in that end cap is shaped on the hole or the window of ventilation.
