Industrialization has produced many patented machines which make life more convenient. Many of these machines require an electric motor for its operation. An electric motor is an essential component to help transform electrical energy into efficient mechanical energy. Normally, motors function through the connection of winding currents for force and the magnetic field. There are motors for every kind of machine. However, there will be times when you should replace the motors and when you need to do so there are specifics you need to know in order to find a replacement.

Uses of Motors

Motor are used in diverse applications. Many industries use them in pumps, fans and blowers, machine tools, power tools, household appliances, and disk drives. Power sources may also differ depending upon country and size of the motor used- generators, inverters, AC (alternating current sources from power grids), and DC (direct current from rectifiers, motor vehicles, or batteries). Electric watches are usually powered by batteries because they have small motors. Ship propellers, pump storage, and pipeline compression require very large electric motors that reach up to 100 megawatts. Motors can be categorized for internal construction, type of motion, and application type among others. Loudspeakers (transducers) and magnetic solenoids (actuators) change electricity into movement, but they do not produce mechanical power that can be used.

Finding the Right Motor Replacements

Searching for the right motor replacement can be a complicated task if you don't know exactly what to do. The following are tips on how you can correctly choose a motor replacement which will fit:

  1. 1
    Locate the part numbers. This can be the most accurate way to identify the correct motor to replace yours. Cross referencing the model or part number from the body of the motor you need to replace is very easy to do. You will be able to see it on the label or nameplate which should be attached somewhere on the motor's outer body. This nameplate may include other data specifications that should also match the replacement part.

    Match the information. Matching the physical dimensions and electrical specifications of your old, defective motor is will help you to find the replacement motor that will fit and work with the machine it is to be used with. You may want to write down all the information from the nameplate, any size specifications for the machine, and electrical specs.

    Consider the company's labeling method. You should take note of the fact that there are companies that make motors for other companies. The motor manufacturer for that machine could easily have placed their exclusive part number on the motor.

    Questions and Answers

    Where can I find the name plate of shipboard ac motor?

    It is usually inside, and you would need to remove the cover. There are also cases where it is placed at the back. It is not always in very obvious places, but it won't be in areas in which it is difficult to see. It contains a lot of useful information, that's why it's not supposed to be concealed.

    If you can't find it, there is likelihood that some repairs had been done and that it has been removed based on warranty.
