Winding Slot Improvement Analysis Of Radial Fec Flux Switching Motor For Optimal Performances

Emily my name is modified spinning. So today I will be presenting about my final project. We titled winding slot improvement analysis of radial field, agitation qualified sushi motor for terminal performance. So for pi, introduction, in 1950, FSN, which flight Hashimoto was introduced in electric motor and the same divided by three part, which is permanent manufacture field, excitation facility motor. And the last one in hybrid, agitation flight Shinto in highs.

We combined with terminal magnet and FPC on. The stator to produce flux. So for the for this design highs is designed in radial FCC. So basically the function of FPC is to give more strength on the flap highs for the operation is exchanging the polarity of the FEC flat link with the amateur coil to the root position. So advantage for the FSM is will give more maximum torque power and more efficiency motor.

Next is problem statement. There is an overlap winding issue between amateur and radial ABC winding. So this figure shows the issue. This amateur this is for the FCC in radial condition. So basically amateur and ABC have their own quality, which is positive and negative.

So this figure I already sketched, the polarity disparity for the amateur disparity for the APC. We know that the flag line will go. Uh will go from negative to positive. We can see this arrow for the flat line for damage. The flat line for the ADC. What the issue here is over overlap happen when the amateur and negative polarity attract with the FAC invader, Condition positive polarity here. So this is what we call it overlap winding.

Okay, the effect from the overlap winding is cause the height coil end to have height losses and high flood saturation in flight distribution and also will decrease the efficiency. Okay to prevent the overlap winding ATC, uh, etc slot and amateur coil slot used to be improved. Next is for part objective. The first objective is to improve the flight distribution of image and field agitation winding slot of FSM. Second is to.

Examine the optimal of motor performance in terms of cog in torque, BMF, flat, leakage flight, distribution and output top of BSM. So for the scope, the first scope is the specification and limit for the cylinder 2 is 12 slots and 14 all BSM is purpose for this project. So basically, uh table one showed the specification of the PSM that we will design.

So the diameter of the stator is 134.5 millimeter. And the radius of the root is 97.25 millimeter. So the ring the angle for root is 5.8571 the row at the.

State angle is 15. So we use the permanent network is one kilogram next scope is the analysis of performance divided by two, which is no load and load phonology will be analyzed in terms of clogging torque by game. F, flat pk, flat distribution. And for now load we will analyze in terms of torque.

JE, at various GA to be analyzed by using Gmail designer for the for electric of maximum 650 volts for bus voltage and maximum current is we use 360 for the MH current density? JA, if you see currency, we use. Fixed at 30, ampere, mill area. So next part is methodology part. This is for the flowchart how to design the FSM design.

First in German geometry, we need to sketch the root stated polynomial, slot, FC and amateur coil. If the design have overlap design, we need to change the parameter or check if the design not overlap. We go to the GMAT designer to set the materials condition circuit mesh and study if not success in safety materials. We need to revise back and change the setting. If success we go to. The call technicians zero root position in zero rota position, we need to adjust the initial angle for the root. So from the coil test, we will choose the angle you face in between range, 90 and 270.

If not we need to back to the coil test and change the angle of root. So if yes we go to the three-phase arrangement. So this figure showed the complete design of the highs for 12 slots and 4 pulse HFS. So this is flowchart for the call test analysis. First we need to analyze 12 called tests. So this. Is for the example, how I generate the 12-volt test in toy col test, we divide by three groups called test, which is an UV this procedure, how to set up the three-phase system to determine you face for the principle in your face is the angle must be 90 to 270 degree in waveform.

So we decide this waveform sq because the angle in range, uh, 90 and 200 and c and 270 degree. So we decide this for the u v w. So, uh, after decide u v w. We will set up to the circuit at j. Max designer to make a three-phase system. So this is for the result for the dual coil test analysis. So basically in 12 cult analysis the current we set to zero so only permanent minus as a primary source will generate multi-magnetic flux. And in this trial coil test also we set the negative 2.2 degree for the initial rotor position to set the 90 until 270 SL phase. So basically this 3 graph is from the 12 coil test, uh, this group for you this group for v, this group for the value. So in group u, we have, uh, coil, three quality coils nine and.

Quarter in group, v, we have coiled 1 coil, 4 qr7 and coil 10 for the coil w. We have call 2 coil 5 equals 8 and quad 11 basically for the form the 12th coil test. We combined one graph to the 4 coil. This is for the coil test analysis. First is convert single phase to three-phase. So basically, uh, 12 coil test analysis is a single phase. Then three coil test analysis is convert from single phase to three-phase. So which is a waveform UV.

We will combine in one graph. So this is for the graph UV phase. So. The maximum amplitude of the magnetic flux is three 0.03183. We move to the no load test analysis.

Clogging. Talk need to be analyzed in this project. The cooking thought will happen when there is a gap in the machine means like a printing mission will have a gap between rotor and setter. So when the cog in torque high will cause the effect to the machine means like vibration and noise.

So the vibration is not good for the machine. So the conventional design I get the cooking stock is nine point. Six.

Newton top peak to peak for the back emf bank f is happened when the voltage generate in electric motor. When there is in the latest motion between the stator winding and the rotor magnetic field. So the maximum value for the induced voltage or back mph for the conventional design is 54.921 volt. So the inner voltage waveform is less.

Distortion can be provided good practical application. So based on this waveform is most likely same to sinusoidal graph. So we can see here less distortion, but for the. Improving we will improve for the beta sinusoidal graph for end f. Next we move to the flat line for no load test analysis. So in no load test, we set the current to zero.

So basically, permanent magnet will generate a productive flux. So basically most of the flood will flow to the center around the FCC. So flux will go to the root, which is a high flux flow into the rotor because the height air gap density.

This will be because of the flood cancellation since when the air gap is very high in slight. Value is again, very big will give more flood cancellation happen. So we move to the flood distribution. So the maximum and minimum flood distribution is one point for maximum 1.8932 detox and for minimum 0.00017 respectively based on this value. So, uh, we can see here, uh, very much flat saturation at the APC. So, uh, flood saturation will affect on the performance of the motor, and also which will give the flood cancellation also to the motor.

So the last part for the result is load test analysis, which is. Torque performance of AVC density. JE, and various MH current density, GA. So this is for the graph of the average output torque versus Jefferson. Ca, so, basically, this step will be referring to this graph. So when j e and j, an equal to zero, j, e and j equal to zero. The top result, obtained, uh, approximately equal to zero and constantly until 30 e. We can see here because, uh, no curry injected into Jenna only depending on the permanent magnet to generate the flux.

So we move to the point number two, which is j. A is set been 25 to 20, which is five to a5 until this blue j20, the output maintain constant the output top maintain constant at 25. Uh.

JE, you can see here apple maintain after after grade 25. JE, so for the point number three is. JA at 25 and JA, at 30., you can see ja825 NGA at 30, the maximum of the top main uh opt-in for the 25 ga25 is 207 eight point, eight, eight, nine, newton top, uh for the 30, uh, j80, uh, sorry. For the g80. We produced a top, uh at 295.26, newton respectively.

So the j. E, for the 30. Where much efficient flood is generated, and the talk is increased it showed that there is no any magnetic saturation or flood cancellation. So in conclusion for this project is there, no load and load test for the output performance has been analyzed the average output torque versus. JE, at various c8 is approximately 295.26 newton top the choking talk for this project, uh is 9.8 newton top.

And the mph is 54.9. So the details need to be investigated for the amateur and FPC coil has has their potential. To improve their performance. So basically in this conclusion, we just finished for the conventional design for the fip2. We will improve the form the competitor design tuber to be better performance. So for the recommendation, the amateur and APC called slot need to be improved to get better performance or optimal performance by follow the no load and load test analysis for the 12 slot and 4 pulse, highs so that's all from me.

Thank you.
