⇒ Auto Transformer provides voltage to the motor at start.
⇒ Appropriate lower voltage tapping –customized as per the application – is provided to the motor.
⇒ After the motor has attained significant torque changeover from Auto Transformer to On Line takes place.
⇒ Interlocking between stator and rotor as per ISS: 8544 (part III).
⇒ Offers improvements in reliability as compared to L.R.S..
⇒ Low maintence; incorporates switching through contactors.
⇒ Smooth acceleration of the slip-ring induction motor.
⇒ Provision of tripping automatically the Starter in case of overload, due to which it gives relief from the worry of burning the motor.
⇒ If there is phase short circuit or earthing in starter outgoing, then MCB of starter will trip automatically due to which fault doesn’t multiply.
⇒ Due to presence of rubber gasket starter is completely protected from dust, mud, water.
⇒ Provision of Starting Starter automatically when all the 3 phases are available, due to which maximum voltage is always available & will give freedom from starting & stopping again-n-again.
⇒ Due to presence of rubber gasket is completely protected from dust, mud & water.
⇒ Incoming & outgoing (3phase, Multi lock type) terminals are provided separately.
Our Products - Auto Transformer Starters Controller Panel
Motor is connected in Delta from the start.
Auto Transformer provides voltage to the motor at start.
Appropriate lower voltage tapping –customized as per the application – is provided to the motor.
After the motor has attained significant torque changeover from Auto Transformer to On Line takes place.
The changeover is “Closed Transition” i.e. during changeover the Auto Transformer acts as a Choke supplying voltage to motor – hence smooth or stepless or soft starting takes place.
The motor then runs on line current.
The transformer is isolated from both the ends to protect the contactors.
Adjustable high torque: A high torque (up to 64%) possible and can be customized by Voltage tapings.
No Power Quality Issues: All standards electrical components ensure that there are NO harmonics or other power quality issues.
Transient Elimination: KORNDORFER Closed Transition technology ensures that Transients are eliminated.
Motor Protection: Motor is connected in Delta at the time of starting to avoid high inrush current in the motor winding thus providing lesser heat generation.
Reduced Voltage Starter: voltage controlled by Auto Transformer at the time of starting.
