Description
Technical field
The present invention relates to technical field of motors, be specifically related to a kind of servomotor adopting amorphous iron core.
Background technology
Servomotor refers to the engine controlling mechanical organ running in servo system, is the indirect speed change gear of a kind of subsidy motor.Servomotor can make control rate, and positional precision is very accurate, voltage signal can be converted into torque and rotational speed with drived control object.Servo motor rotor rotating speed controls by input signal, and energy fast reaction, in automatic control system, as executive component, and there is the characteristics such as electro mechanic time constant is little, the linearity is high, breakaway voltage, the received signal of telecommunication can be converted to the angular displacement on motor reel or angular speed output.Be divided into direct current and the large class of AC servomotor two, its main feature is, when signal voltage is zero without rotation phenomenon, rotating speed is uniform descent along with the increase of torque.
Non-crystaline amorphous metal is by super quench solidification, and during alloy graining, atom has little time ordered arrangement crystallization, and the solid alloy obtained is longrange disorder structure, does not have the crystal grain of crystal alloy, crystal boundary.Existing servomotor adopts silicon sheet core, referring to Fig. 2, the permeability of silicon steel is low, iron loss is high, and hardness is 5/8 times of common silicon steel, and amorphous alloy material has higher saturation magnetic flux density, high resistivity, low-coercivity, low-loss, low exciting power, it changes its permeability by different treatment process, meets different requirements, and has good temperature stability.Also amorphous alloy material is not applied to servomotor field on the market at present.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, provide a kind of Novel servomotor adopting amorphous alloy iron core, by new material application in servomotor field, operating efficiency is high, loss is low, and precision is high, and security performance is high, and lightweight, volume is little, energy-conserving and environment-protective.
For achieving the above object, the technical solution used in the present invention is: it comprises motor housing, end cap, bearing, rotor core and stator core; The side of motor housing is provided with end cap, and the inside of motor housing is provided with rotor core, and the outer cover of rotor core is provided with stator core, and rotor core is connected with motor housing by bearing; Described stator core is amorphous alloy stator iron core; Described rotor core is non-crystaline amorphous metal rotor core; Or described stator core, rotor core are the iron core that amorphous alloy material is made.
Described stator core, rotor core are amorphous alloy iron core or the Modularized splice formula amorphous alloy iron core of integral annular structure.
Described non-crystaline amorphous metal can be replaced and uses amorphous and nanocrystalline soft magnetic alloy material.
Operation principle of the present invention: the present invention's amorphous used servo motor stator core replaces the silicon steel stator core in original servomotor, because non-crystaline amorphous metal permeability is high, under same size, silicon steel motor is different from the power of amorphous servomotor, amorphous power of motor is high, or motor core size can be reduced with during money design of electrical motor, can desired properties be reached equally.
Because non-crystaline amorphous metal resistivity reaches 130 far above 0.45 of silicon steel material, the eddy current loss caused by iron core itself like this and iron loss are very low, and the iron loss of non-crystaline amorphous metal is less than 0.2 when 50Hz1.3T, compare 1.2 iron loss of silicon steel, be about the latter's 1/6, can greatly play energy-conservation effect.
Because non-crystaline amorphous metal is magnetized into magnetic field intensity needed for the magnetic flux density tended towards stability, an order of magnitude lower than silicon steel, so just can reach the object of low exciting current, partition losses for generation of magnetic induction magnetic field reduces, play the temperature rise increasing power or reduce size, reduction induction magnetic core, namely temperature stability is good.
The stator core be made up of non-crystaline amorphous metal has higher saturation induction density (1.45 ~ 1.56T), has high permeability, low-coercivity, low-loss simultaneously, low exciting current and good temperature stability and aging stability.
After adopting said structure, beneficial effect of the present invention is:
One, operating efficiency is high: improve motor working efficiency, make efficiency improve more than 10% on original basis;
Two, loss is low: during empty load of motor, and loss reduces about 70%;
Three, precision is high: have response speed, shorter response time faster than existing motor;
Four, security performance is high: because amorphous alloy material has corrosion-resistant, anti-wear performance, and caloric value is little, can meet the work requirements of special occasions;
Five, it is lightweight, and volume is little: compare and existing servomotor, its lightweight 1/4-1/5, the little 1/3-1/4 of volume;
Six, energy-conserving and environment-protective: compare energy consumption in the production process of silicon steel large, seriously polluted, amorphous alloy material production process is pollution-free, more green.
