Objectives

• After studying this unit, you should be able to
• explain service factor amperage (SFA).
• explain full-load amperage (FLA) and rated-load amperage (RLA).
• explain compressor amperage performance data.
• identify the proper power supply for a motor.
• describe the application of three-phase versus single-phase motors.
• describe other motor applications.
• explain how the noise level in a motor can be isolated from the conditioned space.
• describe the different types of motor mounts.
