Description
[
technical field]
The utility model relates to motor manufacturing, particularly relates to stator component and/or rotor part that armature winding is the motor of feature, particularly relates to the stator core of motor manufacturing.
[
background technology]
Stator core and/or the rotor core of traditional motor all adopt silicon steel material, and iron loss is large, and heating is serious, temperature rise, thus causes inefficiency; Especially under high frequency condition, iron loss is larger.The stator core of the magneto of such as prior art is still based on traditional silicon steel permeability magnetic material, and magneto is because number of pole-pairs is more, and its operating frequency is general all higher, makes magneto temperature rise too high lower with efficiency.
In the loss of motor, iron loss occupies sizable ratio, and these losses have all dissipated with heating form, and non-renewable energy resources improve electric machine temperature rise simultaneously, reduces electric efficiency.Reducing motor iron loss is the large problem of design of electrical motor one, and adopt permeability high, resistance is large, and the new material that eddy current loss is little replaces the direction that silicon steel sheet is motor research and development.The inherent defect of silicon steel sheet in permeability, resistance, eddy current loss and high frequency characteristics etc. makes us cannot produce more high efficiency motor with it.
Amorphous iron alloy material has some row advantages such as high magnetic conduction, high resistance and iron loss are little, utilizes the motor of amorphous iron alloy material manufacture effectively can overcome the above-mentioned shortcoming of the motor that the traditional silicon steel permeability magnetic material of employing manufactures.Amorphous iron alloy material is the new material utilizing flash set technology to manufacture, there is excellent soft magnet performance, also there is high saturated magnetic induction, high permeability low-coercivity, high resistivity and extremely low eddy current effect, therefore iron loss is very little is the advantage of amorphous ferroalloy materials, is silicon steel sheet, permalloy and ferritic regeneration product.Current amorphous iron alloy material has been widely used in transformer, instrument transformer, inductive reactance and motor, greatly facilitates the miniaturization of power electronics power supply and energy-conservation.
Stator core and/or rotor core complex process is become owing to being subject to amorphous iron alloy materials processing at machine field, working (machining) efficiency is low, a series of restrictions such as stock utilization is low, the product price after making it shaping is high, hinders amorphous iron alloy material using in a large number and promoting at machine field.
Amorphous iron alloy material is taken up an official post at the stator core of motor and/or rotor core structure, and what so adopt is traditional structure, because amorphous iron alloy material is amorphous iron alloy band, its width is maximum is no more than 200 millimeters, thickness is about 0.03 millimeter, is therefore processed into stator core and/or rotor core difficulty is very large; Width makes it can not make large-sized motor, and thickness makes its number of laminations too many, and neat more difficult after lamination, this also counteracts that amorphous iron alloy material using in a large number and promoting at machine field.
In recent years, along with constantly to the research of amorphous iron alloy material in the stator core and/or rotor core processing of motor and exploration, but also only do a little improvement in tradition processing and design aspect, therefore or can not effectively improve amorphous iron alloy material the stator core of motor and/or the working (machining) efficiency of rotor core with reduce costs.
Energy-saving and emission-reduction, improve the utilance of material, simplified processing process, and reducing manufacturing cost is the significant task that current enterprise faces.
