Starting and regulating

Overview

Starting and Regulating Resistors

Starting resistors, as the name suggests, are used to limit the current flow during the start of various types of electric motors.The resistance provided by the armature in an electric motor is quite low and hence a large current flows through them during startup. Starting resistors are connected in series with these motors and are gradually disconnected once the motor reaches an optimal speed. In this way starting resistors play an important role in protecting equipment damage due to excess current during the start of an electric motor. Read More

It is important to note that the resistance of the starting resistors will have to be individually tuned for every type of device it is intended to protect.

Since the voltage drop and hence the current flowing through a circuit can be controlled using these variable resistors, they are also used as regulating resistors where they control the amount of current flowing through an electric circuit.

Starting resistors find wide application in high-power electrical devices like:

  • Overhead cranes
  • Truck lifts
  • Conveyor belts
  • Industrial controls
  • Various types of Machine tools

Why KWK Starting / Regulating Resistors?

KWK resistors are available for the following kind of applications:

  • Intermediate stator resistors for switch-on current limiting
  • Starting and regulating resistors for slip ring motors
  • Transition resistors for closed star-delta starting
  • In these kinds of applications, KWK steel-grid fixed resistors or lamina-type fixed resistors are used for which multiple partial resistors are integrated into a single device.

Some of the important features of KWK starting resistors include:

  • Compact design
  • Quick and efficient decrease of voltages up to 1200V
  • No additional protective measures needed
