Description
Technical field
The utility model relate to a kind of can be directly operation in water, the underwater brushless motor of driving, servo and stepping is provided for bathyscaph, deep water torpedo and underwater robot under water.
Background technology
Well known, after motor was put into water, conductive coil can be by the water short circuit, and iron core, bearing, permanent magnetic iron and magnet support bracket thereof can be lost by scale, and the bearing of metal or axle sleeve can get rusty, and the machine shaft that common stainless steel is done pitting can occur in the medium-term and long-term immersion of water.At present, the motor that moves under water all is contained in the capsul and with assurance water is insulated.Machine shaft passes and stretches out shell behind the O-ring seal and do work outward.As be operated in the deep water, also must oiling balance external pressure in the shell.In such structure, the energy of O-ring seal and compensation oil consumption motor, after high speed or the long-time running, O-ring seal and machine shaft wearing and tearing cause the motor water inlet to damage.Increase with hydraulic pressure, O-ring seal also strengthens the pressure of machine shaft, and non-workmanship power increases thereupon.
Summary of the invention
The purpose of the utility model is in order to solve short circuit, the corrosion of metal problem of motor in water, a kind of permanent magnetic brushless that can directly place water to move to be provided, guaranteeing motor pressure balance and don't using compensation oil under water.
The technical scheme of the utility model is: the underwater brushless motor comprises the stator coil winding, permanent magnetic iron rotor, machine shaft, axle sleeve, support and outlet cable.It is characterized in that: the stator coil winding is cast in the epoxy resin, and the surface that permanent magnetic iron rotor and magnet support bracket thereof expose scribbles the epoxy resin protective layer.
Its characteristic also is:
Machine shaft is used the ocean stainless steel;
With axle sleeve and support that polyformaldehyde is made, axle sleeve and support fuse;
The watertight cable of the wet plug of band joint is adopted in the motor outlet.
The utility model makes the inside of stator become the seamless solid that does not have the cavity, the outside layer protective layer that forms with the stator of poured with epoxy resin brushless electric machine.Cast back stator coil winding is isolated with water, and conductive component can short circuit, and the while can be born hydraulic pressure again.
On the surface that the permanent magnetic iron of brushless electric motor rotor and magnet support bracket thereof expose, be coated with epoxy resin, make it, let water can't touch the iron body, avoid magnet and magnet support bracket to be lost by scale at permanent magnetic iron and magnet support bracket appearance formation layer protective layer.
Machine shaft adopts the ocean stainless steel to make, and reduces the pitting of machine shaft to greatest extent.Motor shaft sleeve is processed with polyformaldehyde, make its can provide good lubricated again not can with the water generates chemical reaction, simultaneously, can corrosion.The support of motor is also made with polyformaldehyde, and water is neutral, not can with the water generates chemical reaction, guarantee that not corrosion of electric machine stand has enough rigidity and other mechanical connections again.Simultaneously, support and axle sleeve are connected as a single entity, and make axle sleeve enlarge area of dissipation, can be diffused into the machine shaft heat that axle sleeve produces that rubs in the water fully.The watertight cable of the wet plug of band joint is adopted in the outlet of motor, and motor is connected with external drive circuit through wet plug joint.The node of cable and coil of stator of motor winding is cast in the stator solid.Wet plug joint and watertight cable adopt the silicon rubber parcel.
The beneficial effect of the utility model: the stator coil winding insulate to water, and permanent magnetic iron in the rotor and magnet support bracket thereof and water are isolated, the anti-pitting of machine shaft, and axle sleeve can corrosion, and support is neutral to water, and outlet is the water-stop cable.The underwater brushless motor of the utility model can directly place water to move, uncompensated oil, and no O-ring seal, simple for structure, easy to maintenance, effective power is higher.Its main application is for bathyscaph, deep water torpedo and underwater robot provide driving, servo and stepping under water.
