Embodiment
Fig. 1 to Fig. 5, a kind of magnetic structure of intelligence equipment high-performance permanent magnet synchronous servo motor are referred to, including is determined
Sub- punching 1, rotor punching 2 and magnet steel 3, rotor punching 2 are sheathed in stator punching 1, and magnet steel 3 is arranged on rotor punching 2.
Stator punching 1 is circular ring type, and the inwall of stator punching 1 is provided with 12 stator rabbets being circumferentially angularly distributed
11, the cross sectional shape of stator rabbet 11 is with the trapezoidal of projection.The A/F h of stator rabbet 11 is 4.2mm, stator rabbet
Width has shadow for electromagnetism multiple performances such as the cogging torques, electromagnetic torque, torque ripple of high-performance permanent magnet synchronous servo motor
Ring, under same rotational speed, stator rabbet width increases successively, and electromagnetic torque fluctuation then gradually drops with the increase of width of rebate
Low, stator torque first increases to be reduced afterwards, and the ratio that reluctance torque accounts for electromagnetic torque is also first to increase to reduce afterwards.Stator rabbet 11
Groove depth H is that the facewidth h between 22mm, two stator rabbets is 17.9mm, and the facewidth and groove depth can all influence the magnetic flux density of motor
Distribution, and then influence the performances such as electromagnetic noise and the vibration of motor.
Rotor punching 2 is provided with 10 magnet steel mounting grooves 21 being circumferentially angularly distributed, each mounting groove 21 and is provided with
With the magnet steel 3 of its profiling.The magnetic bridge width D of rotor punching 2 is 1mm, and magnetic bridge width influences for the electromagnetic performance of magneto
Very big, mainly the size of magnetic bridge width can greatly influence the leakage field of magnet, so as to influence the utilization rate and motor of magnet steel
Performance.Therefore, from the utilization rate for improving magnet steel, and then improve the angle of motor performance to consider reduce the width of magnetic bridge as far as possible
Degree, but be due to that magnetic bridge width design obtains too small, then can cause the mechanical strength of rotor not under motor works at higher velocities
It is enough.
The thickness W of magnet steel 3 is 6.3mm, in the increase of same rotational speed lower magnetic steel thickness, the increase of its reluctance torque, magnet thickness
It is bigger, then it can cause the reduction of d-axis inductance, this is unfavorable for weak magnetism speed expansion, also result in electromagnetic torque of the motor in high speed point output
Decline.Because its smaller anti-demagnetization capability of magnet thickness is poorer, when magnet thickness is 6.3mm, the magnetic of magnet steel is close to be more than magnet steel
Demagnetizing curve knee value, and have part surplus.
The subtended angle a of magnet steel 3 is 32.4 °, and the external diameter of stator punching 1 is that 178mm, internal diameter are that 114mm, gas length are 1mm.
The winding method of stator punching is concentratred winding, and the permanent magnet synchronous servo motor of high-end intelligence equipment is to weight and body
Product has extremely harsh requirement, motor is not only reached lightweight, small volume, requirement is also met on electromagnetic performance, just
Need the magnetic Circuit Design of high power density.In order to reach small volume, lightweight, winding mode concentratred winding.Concentratred winding
Winding mode can save more structure space in winding overhang compared with the mode of Distributed Winding, and be also easy to realize automatically
Metaplasia is produced.
The present invention is coordinated using the slot number of the pole of 12 groove 10, and with the obvious advantage in terms of electromagnetic torque, torque ripple, power is close
Degree is high, and is also easy to realize the accurate control of motor.The magnetic Circuit Design of the present invention has very high power density, Ke Yishi
Existing 5 times of overload capacity.
The present invention has the electromagnetic performance of high power density, and can realize automated production.In actual applications may be used
To accomplish small volume, it is lightweight, electromagnetic performance is excellent, is designed for the application characteristic of high-end intelligence equipment, it is easy to accomplish high
Precision control, output high-power.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.
