This tutorial will walk you through how to read a motor plate and set the Motor Overload Relays to the information you gain from the motor plate.

In order to read the motor plate we need to know 3 pieces of information
Whether the motor is wired in star or delta depends on the application. Refer to the electrical diagrams to find out which it is. For example, the saw blade motor is wired in star, whereas most extractor motors are wired in delta.
The UK standard for a three phase electrical supply is 415v at 50Hz. Unless the supply to a motor runs through an inverter (i.e the spindles) this is also the standard for our machines.
Using the picture on the right as an example, we know the motor will be running at 50Hz so we can disregard the information on the right of the plate as this provides figures for a 60Hz supply.
