影響微型減速電機效率有哪些因素

2021-5-26

微型減速電機又稱微型減速馬達,那影響它的因素具體有哪些呢?下面就簡單給大家列舉常見的4項:

  1、周(zhou)期(qi)性(xing)負載(zai)變化(hua)(hua)幅(fu)值的(de)影響周(zhou)期(qi)性(xing)負載(zai)變化(hua)(hua)范圍(wei)越(yue)大,鋁(lv)殼電機轉(zhuan)速(su)離開同步轉(zhuan)速(su)的(de)振蕩越(yue)大,此時籠型繞組中(zhong)的(de)電流也越(yue)大;負載(zai)變化(hua)(hua)范圍(wei)越(yue)小,鋁(lv)殼微型減速(su)機動態效率也相應越(yue)。

  2、轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)慣量(liang)(liang)的(de)影響轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)慣量(liang)(liang)較大(da)時,鋁(lv)(lv)殼(ke)微(wei)(wei)型(xing)電機(ji)在(zai)周期(qi)性負載下(xia)轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)振蕩及(ji)籠型(xing)繞組中(zhong)電流都較小,適當(dang)增大(da)鋁(lv)(lv)殼(ke)微(wei)(wei)型(xing)減速機(ji)轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)慣量(liang)(liang)J對提鋁(lv)(lv)殼(ke)微(wei)(wei)型(xing)減速機(ji)動(dong)(dong)(dong)(dong)態穩(wen)定性是有利的(de),但J增大(da)過多(duo)反而會使鋁(lv)(lv)殼(ke)微(wei)(wei)型(xing)減速機(ji)不穩(wen)定運行。增大(da)轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)慣量(liang)(liang)可以提周期(qi)性負載下(xia)鋁(lv)(lv)殼(ke)微(wei)(wei)型(xing)電機(ji)的(de)動(dong)(dong)(dong)(dong)態效率。

  3、外加電(dian)(dian)(dian)壓(ya)的影響電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)越(yue)(yue)(yue),則鋁(lv)殼(ke)微(wei)型(xing)(xing)減(jian)速機(ji)轉速在周期性負(fu)載下(xia)的波動(dong)就會越(yue)(yue)(yue)小(xiao),籠(long)型(xing)(xing)繞組中(zhong)電(dian)(dian)(dian)流亦(yi)越(yue)(yue)(yue)小(xiao),此(ci)時(shi)鋁(lv)殼(ke)微(wei)型(xing)(xing)電(dian)(dian)(dian)機(ji)的穩定性越(yue)(yue)(yue)好。電(dian)(dian)(dian)壓(ya)下(xia)降會導致周期性負(fu)載下(xia)鋁(lv)殼(ke)微(wei)型(xing)(xing)減(jian)速機(ji)運(yun)行效率降低。

  4、定子電阻的影響定子電阻是鋁殼微型電機在周期性負載下對鋁殼微型減速機動態效率影響較大的一個參數。定子電阻越大,周期性負載下鋁殼微型電機轉速振蕩及籠型繞組中電流就越大,反之亦然。定子電阻下降時,負載變化引起的過渡過程的劇烈程度下降,過渡過程趨短。降低定子電阻值有利于提鋁殼微型減速齒輪箱的機電穩定性,也可以降低此時鋁殼微型減速機的附加損耗,提周期性負載下鋁殼微型減速機的動態運行效率。
