The final element of the equipment description is the equipment boundary figure. A boundary figure is included with each data cell to define the components and limits of the equipment associated with that cell. For example, the data cell boundary figure (Data cell 3.3.7.2.1.1) in Figure 3.2 shows that the centrifugal pump, seal system, motor, motor control unit, lube oil system, coupling, and transmission are all components of the equipment in the data cell. The equipment boundary is inherently reflected in the taxonomy number. 

This chapter gives primary attention to the commonly used general-purpose alternating current motors, although others are noted to acquaint the engineer with the variety of motors, motor enclosures, and mechanical drive turbines available and sometimes used in the chemical and petrochemical industries. Because direct-current motors are not frequently used in the process industries (other than in heavy-duty processes), they are not examined further in this chapter.

Table 14-3 indicates the derating fectors for the effect of altitude on standard Class B motors. Motors are designed to operate within Class B temperature rise limits when operated at rated horsepower at altitudes up to 3,300 ft. For operation of this class of motor at altitudes greater than 3,300 ft at less than the rated horsepower, the derating factors shown in Table 14-3 should be used. 

The importance of constant or variable speed will influence the type of motor, motor-gear, motor-belt, or motor-magnetic drive combination. 

The combination of thermal stability and dielectric performance makes PEN an attractive electrical insulator in electrical motors. Motors with high operating temperatures, such as hermetically sealed refrigerator motors and business machines, need films that are resistant to shrinking and retain nonconducting properties at high temperatures.

Peripheral neuropathies are common neurological disorders that result from damage to the peripheral nerves (Pascuzzi, 2003). The peripheral nerves represent the nerves outside the brain and spinal cord and consist of motor, sensory, and autonomic nerve fibers. Depending on the fiber classes affected, neuropathies are subdivided into motor, motor and sensory, and pure sensory forms. In addition, autonomic disturbances may be present leading to the additional classification into autonomic or autonomic and sensory neuropathies.
