Star-Delta Motor Starter Panel

Emax Control is a system integrator specializing in Star-Delta Motor Starter Panel Malaysia.

There are many ways to run an AC Induction motor and Star-Delta remains one of a popular and cost effective methods to start the motor. For more information on motor controllers, feel free to visit the Wikipedia page.

Star-Delta panels are simple and relatively cheap but lacks the advantages of an inverter or variable speed drive. For example, the Schneider ATV310 comes with the following motor protection built-in:

  • Motor overload/overcurrent
  • Motor short circuit
  • Output phase loss (cable disconnected)
  • Input phase loss
  • Ground short circuit
  • and many more…

An inverter or variable speed drives also greatly reduces the inrush current or current spike and this is important if frequent start/stops are required. Inrush current can contribute to increased energy consumption from a typical motor.
