Three phase induction motors have a very simple construction composed of a Motor Induksi china stator covered with electromagnets, and a rotor made up of conductors shorted at each end, arranged as a “squirrel cage”. They focus on the basic principle of induction where a rotating electro-magnetic field it developed through the use of a three-stage current at the stators electromagnets. This in turn induces a current inside the rotor’s conductors, which in turns creates rotor’s magnetic field that tries to check out stator’s magnetic field, pulling the rotor into rotation.
Hal-hal hebat tentang Motor Induksi AC adalah:
Motor induksi sederhana dan strukturnya kokoh. Mereka memiliki kualitas yang lebih baik dan dapat beroperasi dalam kondisi lingkungan apa pun
Induction motors are cheaper in expense because of simple rotor construction, absence of brushes, commutators, and slip rings
They are free of maintenance motors unlike dc motors due to the lack of brushes, commutators and slip rings
Induction motors could be operated in polluted and explosive environments as they don’t have brushes that may cause sparks
AC Induction motors are Asynchronous Machines and therefore the rotor does not convert at the specific same speed because the stator’s rotating magnetic field. Some difference in the rotor and stator quickness is necessary in order to develop the induction into the rotor. The difference between the two is named the slip. Slip must be kept in a optimal range in order for the motor to operate effectively. Roboteq AC Induction controllers could be configured to operate in one of three modes:
Scallar (or Volts per Hertz): an Open up loop mode where a control causes a simultaneous, fixed-ratio Frequency and Voltage change.
Controlled Slip: a Shut Loop speed where voltage and frequency are controlled to keep slip within a narrow range while operating at a preferred speed.
Kontrol Berorientasi Bidang (Penggerak Vektor): Kontrol Kecepatan dan Torsi Loop Tertutup yang berfungsi dengan mengoptimalkan bidang putar stator vs. bidang induksi ini pada rotor.
