WWS Series Definite Purpose Motor Starters. The WWS Series definite purpose across-the-line starter provides compact load control for application-specific use. These starters are available in single-phase units up to 10 HP @ 230VAC and in three-phase units up to 50HP @ 230VAC and 100HP @480VAC. Direct 415 V will be applied to the 3 phase motor or any unit. Motor’s connection is depending upon the application requirement. It may be star or delta (in most of the cases delta connection are used).

There can be two types of control using soft starter: Open Control: A start voltage is applied with time, irrespective of the current drawn or the speed of the motor.For each phase, two SCRs are connected back to back and the SCRs are conducted initially at a delay of 180 degrees during the respective half-wave cycles (for which each SCR conducts).

Auto transformer Starter An Auto transformer Starter is suitable for both star and delta connected motors. In this method, the starting current is limited by using a three-phase auto transformer to reduce the initial stator applied voltage.
Manual motor starters can provide on/off operation and overload protection for many small 1-phase, 3-phase, or DC motors in small machine tool, pump, fan, and conveyor applications. Motor starter accessories maintain and modify motor starter models.
The output of the motor starter goes to a three phase AC motor. Power is supplied by connecting a step down transformer to the control electronics by connecting to phases L2 and L3. The lower voltage is then used to supply power to the left and right rails of the ladder below. The neutral rail is also grounded.

  • Inside the cotrol box there is 3 phase 480 coming in to a motor starter and overload. These run the electrical motor which turns the centrifuge. THIS ALL WORKS AS IT SHOULD. From here there are jumper wires for L1 L2 L3 that go to a smaller motor starter and overload. Which runs the pump. The pump can only be turned on once the centrifuge is ...
  • Included in the panel is a direct-on-line type starter for a 2hp, 230 Vac, 3-phase chlorine booster pump. It shall have a 20AT 3-pole circuit protector for isolation. It shall also have an appropriately sized magnetic contactor and thermal overload relay that takes into consideration the full load amperes rating of the booster pump motor.
  • The most fundamental, economical, as well as an easy method for running a three-phase induction motor is named as the DOL starter. This starter joints three phase motors straight across the supply of three phases. The attractiveness of this kind of starter is, it can be connected straightly to the motor, and it doesn’t affect the induction motor. The Direct Online Starter consists of a protective device as well as main contacts. Let us discuss an overview of DOL.
