Tz10=2.27(N.m) Tz05=3.84(N.m) Jr=0.0024(kg.m^2) t0=0.66(s)
Gcu1=1.78(kg) Gal2=0.40(kg) Gfe=10.9(kg)
Ccu=65.0(元) Cal=15.8(元) Cfe=6.4(元) 主材成本=192.1(元)
三、铁心
硅钢片牌号:50W540 KFe= .98
D1= 130 Di1= 80 Q1= 24
D2= 79.5 Di2= 26 Q2= 22
ZC1= 1 b01= 2.2 bs1= 5.9 R= 4.2
zs1= 30 hs0= .5 hs12= 10.6
ZC2= 2 b02= 1 br1= 5.5 r2= .85
zs2= 30 hr0= .5 hr12= 14.6
L= 80 g= .25 GFe=10.9(kg) Φ=237510
Bt1=15255 Bt2=15521 Bc1=13646 Bc2=13667 Bg=7065
ATt1=10.3 ATt2=17.6 ATc1=8.1 ATc2=1.8 ATg=178.3 AT=216
四、绕组
定子绕组型式:单层链式, 60°相带, 线规: 1 xΦ .75 /Φ .81
转子绕组型式:铸铝单鼠笼
y1=5.00 A1=1 d1=15.0
q1= 2 z1=98 zΦ1=784
τy1=63.4 α1=36.1 Fd1=23.1 Lz1=183.5 Hw1=1.5 Si1=0.25 Sf1=0.764
SK=1.10 Srr=140
Gcu1=1.78(kg) R1(75℃)=7.068116(Ω) r1_=0.0367 J1=3.95
Gal2=0.40(kg) R2'(75℃)=6.618483(Ω) r2_=0.0344 J2=2.70 Jr2=1.80
五、漏抗
x1_=0.0559 x2_=0.0766 x_=0.1325
x1s_=0.0360 xs2s_=0.0157 xd2s_=0.0179 xe2s_=0.0034
xsks_=0.0092 x2s_=0.0462 xst_=0.0822
L1=34.252(mH) L2'=46.921(mH) Lm=826.784(mH)
R1(75℃)=7.068116(Ω) R2'(75℃)=6.618483(Ω) Rm=16.185500(Ω)
X1=10.760590(Ω) X2'=14.740660(Ω) Xm=259.741900(Ω)
六 、电流
i1_=1.5325 i2_=1.2223
im0_=0.9764 im_=0.7412 ix_=0.2058 iR_=0.9470 ip_=1.2048
I1=1.75/1.75(A) I2=143.83(A) Ir2=251.80(A) Ikw=1.14(A)
空载电流 = 1.12/1.12(A) 堵转电流( 100 V ) = 2.05/2.05(A)
七、损耗
pcu1_=0.0862 pcu2_=0.0514 pFe_=0.0462 ps_=0.0200 pfw_=0.0133 pg_=0.2171
Pcu1=65(W) Pcu2=39(W) PFe=35(W) Ps=15(W) Pfw=10(W) Pg=163(W)
空载损耗 (75℃)= 70.9(W)
堵转损耗( 100 V / 75℃) = 197.2(W) 堵转损耗(额定电流 / 75℃) = 142.6(W)
八、起动性能
r1_=0.0367 r2s_=0.0357 rst_=0.0725 xst_=0.0822 zst_=0.1096
