Stator ahụ:
Nhazi stator nke moto squirrel-cage na moto slip-ring bụ otu ihe ahụ. Isi ihe dị iche na moto induction slip-ring dị na nhazi rotor na ụdị ọrụ. Mgbe ejiri moto slip-ring na sistemụ cascade, enwere ike ịhụ mgbanwe ụfọdụ na stator n'ihi na ike ọkọnọ nke moto ahụ sitere na njikwa ike nke rotor nke moto slip-ring ọzọ, ebe etinyere resistor mpụga na rotor ya.
Rotọ:
Kedu ihe bụ mgbanaka mgbagharị? Moto mgbagharị na-enwekarị rotor nwere stator nke na-egbu egbu. Ụdị rotor a nwere eriri okpukpu abụọ nke nwere akụkụ atọ, nke mejupụtara eriri ndị ejiri na jenerato AC. Ejiri ígwè mee isi rotor ahụ ma nwee oghere iji kwado eriri atọ nke nwere akụkụ atọ. A na-ekewa windings ndị a site na ọkụ eletrik site na ogo 120. Ọ bụrụgodị na a na-emerụ stator ahụ n'ụdị abụọ, ọnụọgụ nke windings stator merụrụ ahụ na rotor ahụ bụ otu ihe ahụ dị na stator ma na-abụkarị usoro atọ. A na-eduga windings atọ ndị a site na nsọtụ nke ọzọ n'ime ma jikọọ ha na mgbaaka mgbagharị atọ nke etinyere na ogwe rotor n'onwe ya. Ọdụ atọ ahụ na-akpọtụrụ mgbanaka mgbagharị atọ ndị a site n'enyemaka nke ahịhịa carbon, nke ihe ndị mejupụtara mmiri na-edozi na mgbaaka ahụ. A na-ejikọkwa ahịhịa carbon atọ ndị a na mpụga na njikọ mmalite nke usoro atọ. Mgbanaka mgbagharị na rheostat mpụga nwere ike ime ka iguzogide mpụga nke sekit rotor dịkwuo elu, na-eme ka ọ nwee iguzogide dị elu n'oge mmalite, si otú a na-eme ka ike mmalite dịkwuo elu. N'ọnọdụ ọrụ nkịtị, mgbanaka mmịpụta ahụ na-emecha sekit ahụ na akpaghị aka site na mgbanaka aka uwe ígwè. A na-akwagharị mgbanaka aka uwe ígwè ahụ n'akụkụ ogwe ahụ, na-eme ka mgbaaka atọ ahụ metụ ibe ha aka. Na mgbakwunye, ahịhịa ndị ahụ na-ebuli onwe ha na akpaghị aka site na mgbanaka mmịpụta ahụ iji zere mfu esemokwu na mmebi. N'ọnọdụ ọrụ nkịtị, ọrụ nke rotor mgbanaka mmịpụta ahụ bụ otu ihe ahụ dị ka rotor nke squirrel-cage.
Gịnị ga-eme ma ọ bụrụ na etinyere resistor mpụga? N'ihe gbasara injin induction nke squirrel-cage, nguzogide rotor dị obere nke ukwuu, yabụ ọkụ eletrik dị na rotor dị elu nke ukwuu, nke na-eme ka ọkụ eletrik mmalite ka njọ. Agbanyeghị, ọ bụrụ na etinyere resistor mpụga n'ihe gbasara moto slip-ring, nguzogide rotor na-abawanye na mmalite, yabụ ọkụ eletrik rotor dị ala ma ọkụ eletrik mmalite dị oke. Ọzọkwa, slip achọrọ iji mepụta ọkụ eletrik kachasị dabara na nguzogide rotor. Na moto slip-ring, site n'ịbawanye resistor mpụga iji mee ka nguzogide rotor dịkwuo elu, slip na-abawanye. N'ihi nguzogide rotor dị elu, slip na-abawanye, yabụ ọbụlagodi na obere ọsọ, enwere ike nweta torque "pull-out". Mgbe moto ahụ ruru ọsọ ya bụ isi (ọsọ zuru oke), mgbe ewepụrụ resistor mpụga ma n'okpuru ọnọdụ ọrụ nkịtị, ụdị ọrụ ya bụ otu ihe ahụ na nke moto induction nke squirrel-cage. Ya mere, moto ndị a kacha mma maka ibu inertia dị elu, nke chọrọ ihe fọrọ nke nta ka ọ bụrụ torque pull-out na obere ọsọ na ọsọ ọsọ ruo ọsọ zuru oke, ma na-amịkọrọ ọkụ eletrik kacha nta n'oge dị mkpirikpi.
Uru nke moto induction slip-ring:
Uru kachasị nke moto induction slip-ring bụ na ha nwere ikenwee ike ijikwa ọsọ ngwa ngwa.Ọbụlagodi na ọsọ efu, enwere ike nweta "torque-pull-out". Ma e jiri ya tụnyere moto induction cage squirrel, o nwere torque mmalite dị elu. Torque ibu zuru oke dị ihe dịka 200-250% nke torque ibu zuru oke. Moto induction cage squirrel na-aza maka 600-700% nke torque ibu zuru oke, mana torque mmalite nke moto induction slip-ring dị obere nke ukwuu, ihe dị ka 250-350% nke torque ibu zuru oke.
