MOTOR REPLACEMENTS
Motor replacements are assumed to be in lieu of re-winds or at time of failure, and the incremental cost (and savings) is calculated off a National Electrical Manufacturers Association (NEMA) standard efficiency motor for the same size and application. The credits/reimbursements are found in the tables below.Irrigation motor rebates require that the motor is open drip proof (ODP) or totally enclosed fan cooled (TEFC), operates at 1,800 rpm, and is replacing older or rewound motors. Other types of motors will need to be submitted as custom proposals.Industrialization has brought on so many patented machines that make man’s life so much more convenient. One of the essential components needed to run a machine is the electric motor. An electric motor is a machine that transforms 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 and they can go on for long periods. However, there will be times when you should replace them. Doing so means that you have to find the right replacement motor.Motor are used in diverse applications. Many industries use them in pumps, fans, machine tools, blowers, power tools, household appliances, and disk drives. Power sources for every motor also differ -— generators, inverters, AC (alternating current sources from power grids), and DC (direct current from rectifiers, motor vehicles, or batteries). Electric watches have very small motors. Ship propulsion, 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.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 end up with the right motor replacement that you need:Find the part number and cross reference it. This can be the most accurate way to locate a replacement motor.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 placed on the motor. Other data, such as volts and horsepower, are also found on the nameplate.Match the motor specs or specifications. Matching the physical dimensions and electrical specifications of your old, defective motor is also a very helpful way to find the replacement motor that you want.You will need all the information about the mounting, shaft size, and electrical specs so that your motor replacement can be successful.Consider the company’s labeling method. The nameplate you’re looking for may have different numbers for identification.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.
