As we discussed in our previous blog a motor starter has 4 main functions: to safely start a motor, to safely stop am motor, to channge the direction of a motor, and to protect the motor from low volatge and or overcurrent. Not all motor starters have the reversing capability.
Electric motors are classified as an inductive load, which means it requires an enormous amount of power to get up to speed, then a relatively small amount of power to maintain that speed. This initial surge of power is called inrush current. Although short, it can be several times the steady-state current. To provide the motor with protection from the inrush current a motor starter is used.
There are several types of motor starters manual or magnetic, variable frequency drives (VFD), and soft starters. Manual magnetic motor starters are primrily used with small HP motors, usually less than 1O HP. For motors that need more control and programability a VFD or a soft starter may best for the applications.
