Selection

More than one type of motor may be used as a replacement in many applications. Four key factors play a prominent role in the process of selecting a replacement motor that will be compatible with a particular piece of equipment.

1. Mechanical requirements of the driven load.
   
2. Electrical system supply.
   
3. Physical and environmental conditions.
   
4. Efficiency and economic considerations.

The use of electric motors involves high concentrations of electrical power, which is potentially very dangerous. Hazardous operations diminish through the proper selection, installation, and use of a motor. When selecting a motor, one should consider the overall safety of the system, as well as the risks inherent to particular motor types.

Most of the information pertinent to the motor selection process is present on the original motor's nameplate. Ultimately, motor selection is a compromise among these four considerations and the availability of particular motor types.
