Abstract
The invention provides an armature cup performance analysis method for hollow cup motor windings. The terminal resistance of a winding armature cup, the number of winding turns, the dimension of the end portion of the winding armature cup and the thickness of the winding armature cup are adopted as objects. According to the method, firstly, the cutting lengths of the effective magnetic lines of winding armature cups wound according to different winding methods are compared and analyzed. The larger the cutting length of an effective magnetic line, the better the performance of a winding armature cup. Secondly, on the premise that the cutting lengths of the effective magnetic lines and the numbers of winding turns are the same, the wire lengths of winding coils are compared and analyzed. When the wire length of a winding coil is shorter, the internal resistance is smaller. Meanwhile, the copper loss is reduced, so that the performance of the winding armature cup is better. Thirdly, on the premise that the cutting lengths of the effective magnetic lines and the numbers of winding turns are the same, the dimensions of the end portions of winding armature cups are compared and analyzed. When the dimension of the end portion of the winding armature cup is thinned, the air gap gets smaller. In this way, the performance of the winding armature cup is better. Based on the above method, the difference among windings can be preliminarily estimated before the winding selection process.

In the present embodiment, minimum volume maxon companies of Switzerland proposed in recent years by the method for the present invention and quality energy
The winding construction of torque, best hollow-cup motor EC_PowerMax for obtaining maximum is analyzed, and with it is internationally recognizable
German Dr.F.Faulhaber Faulhabers company mature technology, the conventional oblique armature winding cup of straight forming and Switzerland
The ripe oblique armature winding cup of cans of maxon company techniques carries out performance relative analyses, draws EC_PowerMax motors
The superior function of armature winding cup, illustrates why the armature winding cup of EC_PowerMax can be made with knot with its unique performance
Structure, same to size, there is " maximum power density " with the hollow-cup motor of material, so as to verify a kind of drag cup that this patent is related to
The feasibility of the analysis method of machine winding armature cup performance.
The oblique armature winding cup of straight forming of German Dr.F.Faulhaber Faulhabers company, the volume of maxon companies of Switzerland
The oblique armature winding cup of bent molding belongs to crossing group, and simply winding mode is different, and direct coiling molding crossing group armature cup is suitable for
In the less armature cup of draw ratio, cans crossing group is applied to the larger armature cup of draw ratio, for this purpose, choosing one of which
The oblique armature winding cup of winding mode carries out performance relative analyses with the armature winding cup of EC_PowerMax motors.
On the basis of being analyzed by the armature winding cup material object and structural profile to EC_PowerMax motors, draw
The structural arrangement of the armature winding cup is as shown in figure 1, what it was made up of several independent coils.EC_PowerMax motors
Armature winding cup is known as " maximum power density motor " with its unique performance by maxon companies, it and oblique armature winding cup
Motor is compared with prominent advantage, is mainly reflected on armature cup winding special performance：
1) EC_PowerMax machine windings armature cup loop geometries are symmetrically well-behaved, separate in arrangement, mutually do not do
Relate to, the overlap number of plies of end is few, greatly reduces end turn thickness, be easy to arrangement, be applicable to the electricity of various overall dimensions
Machine；
2) on little support motor, especially on high power density motor, while effectively reducing magnetic air gap, increase greatly
Add under the effective length of coil cutting magnetic field, and equally effective cutting magnetic line state, EC_PowerMax motor winding wires
Circle is shorter with line length than oblique winding coil, and internal resistance is little, reduces copper loss；
3) as end coil is relatively thin, magnetic air gap reduces, and effectively increases the utilization rate of permanent magnet, for same output work
The motor of rate, due to the raising of permanent magnet utilization rate, can use the magnetic property of the permanent magnet or volume point of magnetic property relative mistake
Strong permanent magnet can meet output power of motor, reduce cost, reduce volume.
During being analyzed using the inventive method, different armature winding cup winding structures are dissected, used " figure+numeral "
Method, not only intuitively, even more go out the difference of the crucial technical parameter of armature winding cup with concrete digital quantization.From point of theory

Line, is all covered with 294 sections of lines of needs by EC_PowerMax machine windings, can save line 2%, and certain model batch product low-power machine is
The oblique armature winding cup of straight forming, 600 circle of armature cup, per 150 millimeters of circle, add up to 90 meters, can save line 1.8 using Concentrical winding
Rice, so crossing group more takes line, not only increases cost, it is often more important that phase resistance increases, and increases copper loss.
3) the unnecessary line of crossing group is predominantly located at end, and end is two thickness, and EC_PowerMax electric motor winding ends are one layer
Thickness, armature wall of cup are thin, and air gap reduces.
It can be seen that, under equivalent technology parameter, EC_PowerMax machine windings have unique advantage：1) overlap of end
The number of plies is few, and magnetic air gap reduces, and effectively increases the utilization rate of permanent magnet；2) under equally effective cutting magnetic line state, with one heart
Formula winding coil is shorter with line length than oblique winding coil, and internal resistance is little, reduces copper loss；3) for the motor of same output, by
In the raising of permanent magnet utilization rate, with the strong permanent magnet of the magnetic property of the permanent magnet of magnetic property relative mistake or volume point can be
Output power of motor can be met, cost is reduced, volume is reduced.
Not only it is coincide with Structural Performance Analysis expected result using the method, and more intuitively and explanation can be quantified
