Star Delta starter comes under the category of starters using reduced voltage method for starting the motor. Just like all other starters, the basic aim to use this starter is to decrease initial high starting current generated by the motor at the starting procedure....
An Auto transformer starter basically uses an auto-transformer to reduce the voltage applied to a motor during its start. As we know that the starting of big motors which are used for prolonged periods exert large current in the circuit. Due to this, a...
The most simple and basic type of starter for motors (induction motor) is the Direct Online starter. The Direct on line starter contains an ON/OFF switch and an OLR. Here, OLR stands for overload relay for protection against excessive load current. The selection of...
A face plate/drum type controller is used for starting the series motor. This controller can also be used to control the speed of a series motor as well as to reverse the direction of its rotation. It is commonly known as Series motor starter.
As...
Four point starter is connected to a long-shunt compound motor. If we compare it to the generally used 3 point starter, we can easily mark one remarkable difference than its counterpart. In four point starter, the most critical 'Hold ON coil' (electromagnet) is placed...
