Description
Technical field
The invention belongs to field of motor manufacturing, and in particular to a kind of transverse magnetic flux reluctance type low speed high torque directly drives together
Walk motor.
Background technology
The direct driving motor of low speed high torque has eliminated bulky deceleration mechanism, avoids complicated, and rotary inertia is big,
Efficiency is low, oil leak, abrasion, safeguards the various adverse effects such as frequent.The direct driving motor of low speed high torque is drawn in metal
The mechanical, electrical terraced drag device of silk, hoisting machinery, tower-type pumping unit, mineral explosion-proof motor, Air-Cooling Island wind turbine, belt-conveying, wind-force hair
The fields such as motor have extensive use.
It realizes low velocity of the motor less than 100r/min, high torque density, directly drive, it is necessary to realize number of pole-pairs >=30
Design and manufacture.Based on motor essence electromagnetic structure difference, existing radial flux motors are being realized with transverse flux motor
There are two kinds of completely different technical solutions in the design of multipole logarithm and manufacture of motor.
In the existing direct driving motor of radial flux low speed high torque, to realize that multipole logarithm designs, it is necessary to increase
Per the number of windings under extremely every phase.The number of windings is usually corresponding with the slot number of stator core, this, which means that, will accordingly increase stator
The slot number of iron core.In order to reduce the total slot number of stator core, MgO-ZrO_2 brick q=Q/2mp is typically designed to point less than 1
Number.Wherein, q is MgO-ZrO_2 brick, and Q is electric machine stator iron slot number, and m is the number of phases, and p is number of pole-pairs.Q is less than 1, though it is so that every
Slot number is reduced under extremely per phase, but essence is that the sulculus of greater number is replaced with fewer number of large trough.
In existing radial flux motors structure, the slot where teeth portion and armature winding that magnetic flux passes through occupies same circular ring shape
Section, plane where the magnetic line of force are parallel to the direction of rotation of motor, and the sectional area of slot and the sectional area of teeth portion condition each other.If
It needs to flow through larger electric current, it is necessary to which larger winding cross section product, the sectional area of teeth portion is just affected, and (saturation can make
Magnetic flux reduces)；Vice versa.If the sectional area of teeth portion and the sectional area of slot increase simultaneously, the half of motor will necessarily be increased
Diameter, makes the torque density of motor reduce.Therefore, output torque is difficult to be improved at all.It is above-mentioned by MgO-ZrO_2 brick q=Q/
2mp is designed as the score less than 1, and the sulculus of greater number is only replaced with fewer number of large trough, can not reduce the number of windings
Total sectional area of slot shared by amount and winding.In the electromagnetic structure of existing radial flux motors, multipole logarithm is realized
Design of electrical motor inevitably increases the radius of motor, makes the torque density of motor reduce.
In transverse flux motor because magnetic circuit is detached with circuit, and is mutually perpendicular in space, magnetic circuit iron core and circuit around
The size of group can be adjusted independently, and design freedom is big, can effectively improve power of motor and torque density, multiphase easy to implement,
The structure design of multipole logarithm keeps high efficiency and big torque in low speed.The force density that transverse flux motor obtains is existing
3-5 times of radial flux motors.
The design method of transverse flux motor multipole logarithm, can be expressed as：Under identical rated power, it can not increase
Big motor diameter size does not change the size and parameter of phase winding, mainly folds thickness by reducing stator and rotor iron core, increases and determines, turns
Sub- iron core quantity is realized.
The essence defect of existing radial flux motors electromagnetic structure is confirmed with an example, illustrates transverse flux motor
The significant advantage of electromagnetic structure.Water tank drawbench is widely used in steel wire rope manufacturing, there is a common water tank drawbench,
High-speed wire-drawing cone pulley rotating speed is about 90r/min, in order to eliminate bulky deceleration mechanism, improves motor power saving rate, it is desirable that is selected straight
Connect the torque motor of driving.Under power frequency 50Hz, the number of poles for directly driving torque motor is set as 60, rotating speed 100r/min.It is right
The motor is driven using frequency converter frequency reducing so that motor speed reaches 90r/min.It is designed using existing radial flux configurations, i.e.,
Make under the conditions of water cooling, motor appearance and size is still huge, and seat No. is bigger by 5 than 10 pole motors of same nominal power, 6 etc.
Grade.Actual conditions are that most of steel wire rope factories do not have the condition for providing water cooling.Under the conditions of air-cooled, the radial direction magnetic of 60 poles
Logical permanent magnet torque motor internal temperature rise is up to 100 DEG C or more, this is for the class of insulation and Nd-Fe-B permanent magnet of enameled conducting wire
Operating temperature grade proposes very high requirement, and motor cost is caused to improve.In the design of multipole logarithm motor, conventional diameter
Be to the essence defect of the electromagnetic structure of flux electric machine, radial flux motors can only by increase stator core slot number and
The number of windings in slot realizes that the multipole logarithm of motor designs, and necessarily motor diameter is caused to increase, connects per phase winding
Conductor total length increases, and conductor overheating loss increases.
Switched reluctance machines have position detector, the mission nonlinear that torque ripple is big, needs rotor magnetic pole, and magnetic field is jumps
The shortcomings of jump property rotation, control system is complicated.In contrast, market is with greater need for the reluctance-synchronous machine convenient for controlling and driving,
Alternating current or inverter supply can be used directly.
