Tambayar da Duka da Wace Mawakin Indukshin da Rotori Mai Zafi da Squirrel Cage Induction Motors

Wace Mawakin Indukshin da Rotori Mai Zafi (WRIM) da Squirrel Cage Induction Motors (SCIM) suna ne biyu daga cikin mawaki masu yawa a kan indakama na mawaki. Haka su ne muhimmanci duka da duka:

1. Tashar Rotori

Wound Rotor Induction Motor (WRIM):

• Rotori ya shafi sashe uku na zafi mai sarrafa a kan ci gaba da sabon kungiyoyi bayan slip rings da brushes. Wannan ya ba rotor windings lafiya a kan ci gaba da sabon kungiyoyi ko wasu wurare.

• Ya ba da kyau a kan ci gaba da sabon kungiyoyi ta rotor, wanda ya ba da kyau ga tushen da kuma ido mai tsarki.

Squirrel Cage Induction Motor (SCIM):

• Rotori an yi amfani da aluminum ko kopper bars a cikin tashar mai yawa, domin hakan ya fi sune sunan "squirrel cage motor."

• Wannan tashan ya fi yawa da kuma za a iya kula, babu slip rings ko brushes, wanda ya ba da rike da lalace-rake. Amma, ba a iya ci gaba da rotor current ba.

2. Tushen Da Kuka

Wound Rotor Induction Motor (WRIM):

A tushen da kuka, ana iya kara resistors a kan rotor windings don kawo kasa da kasa mai tsarki da kuma karɓe kasa mai tsarki. Idan mawaki ya faru, ana kawo kasa resistors har zuwa lokacin da ake gina.

Yana ba da kyau ga tushen da kuka, wanda ya fi yawa ga wasu abubuwa masu buƙata mai tsarki, kamar cranes, conveyors, da kuma pumps masu yawa.

Squirrel Cage Induction Motor (SCIM):

A tushen da kuka, rotor current ya fi yawa, wanda ya ba da kasa mai tsarki, yawanci 6-8 kafin rated current. Karɓe kasa mai tsarki ya fi kadan, kamar 1.5-2 kafin rated torque.

Don kawo kasa mai tsarki, ana iya amfani da star-delta starters ko soft starters, amma ba a iya ba da kyau kamar WRIM ba.

3. Sarrafa Ido

Wound Rotor Induction Motor (WRIM):

Rotor windings ana iya sarrafa a kan ci gaba da sabon kungiyoyi, wanda ya ba da kyau ga sarrafa ido. Wasu hanyoyi masu kyau sun haɗa da rotor resistance control da cascade control.

Idan wannan hanyoyi ya fi yawa da VFD control, yana fi yawa ga wasu abubuwa masu buƙata ido.

Squirrel Cage Induction Motor (SCIM):

Squirrel cage motors masu zamani ba su da kyau a kan sarrafa ido, saboda ido na amsa ce an yanayi da supply frequency. Don samun sarrafa ido, ana iya amfani da VFD don yanayi supply frequency.

VFD control ya ba da kyau ga sarrafa ido, amma ya saukarci cewa ya fi yawa da al'amuran ciki da kuma cost.

4. Tsarin Yadda Ake Yi Waɗannan Abubuwa da Kula

Wound Rotor Induction Motor (WRIM):

Sunan slip rings da brushes ya ba da kyau ga kula, kamar yanayin binciken da kuma kula brushes. Friction daga slip rings da brushes ya ba da kasa mai yawa, wanda ya ba da kyau ga efficiency.

Amma, a wasu abubuwa masu buƙata tushen da kuka, kawo kasa, ko sarrafa ido, kyau ga performance ya fi yawa da kula.

Squirrel Cage Induction Motor (SCIM):

Babu slip rings ko brushes, tashan ya fi yawa, kuma kula da kyau, wanda ya ba da kyau ga operation da yawa da tsari.

Efficiency ya fi yawa, musamman a cikin ido mai yawa, saboda ba a bai additional mechanical friction losses ba.

5. Fannon da Suke Amfani da Su

Wound Rotor Induction Motor (WRIM):

Yana da kyau ga wasu abubuwa masu buƙata karɓe kasa mai tsarki, tushen da kuka/ kawo kasa, da kuma sarrafa ido, kamar:

• Cranes

• Conveyors

• Fans

• Pumps

• Rolling mills a cikin takardun metalurgiya

Squirrel Cage Induction Motor (SCIM):

An yi amfani da ita a cikin wasu abubuwa masu industrial da ba su da kyau ga sarrafa ido ko karɓe kasa mai tsarki, kamar:

• Air conditioning systems

• Ventilation equipment

• Water pumps

• Conveyor belts

• Agricultural machinery

6. Cost

Wound Rotor Induction Motor (WRIM):

Saboda tashar ya fi yawa, cost of manufacturing ya fi yawa, musamman da need for additional components like slip rings, brushes, and control systems.

Yana da kyau ga wasu abubuwa masu buƙata, inda initial investment ya fi yawa, amma kyau ga performance zai iya ba da kyau productivity over time.

Squirrel Cage Induction Motor (SCIM):

Tashar ya fi yawa ya ba da kyau ga cost of manufacturing, wanda ya ba da kyau ga wasu abubuwa masu general-purpose industrial equipment.

Yana da kyau ga wasu abubuwa masu cost-sensitive, musamman da ba su da kyau ga complex control ko speed regulation features ba.

Muhimmiyar Tambaya

Wound rotor induction motors da squirrel cage induction motors suna da kyau da dukan su. Zan iya zabe wadannan duka don haka ga muhimmin abubuwan da ke neman. Wound rotor motors suna da kyau ga tushen da kuka da kuma sarrafa ido, wanda ya ba da kyau ga wasu abubuwa masu buƙata karɓe kasa mai tsarki da kuma sarrafa ido. Amma, squirrel cage motors suna da kyau ga simplicity, low maintenance, da kuma cost-effectiveness, wanda ya ba da kyau ga wasu abubuwa masu standard industrial equipment.
