ELECTRIC MOTORS AND STARTERS
and appliances Motors range in size from fractional-horsepower clock motors to industrial giants rated for more than 500 hp, and they provide the driving power for equipment as diversified as electric trains, elevators, escalators, street cars, cranes, and ocean-going ships Electric motors are broadly classified as direct current (DC) or alternating current (AC), although universal motors can be powered by either AC or DC Motor identification and classification are complicated and can be quite confusing because of the similarities in features and construction that span the divide between AC and DC motors To clarify the situation, Fig 10-1 shows the interrelationships of the leading characteristics of motors It identifies the four generic types of DC motors and the five generic types of AC motors, excluding the universal motor There are both singlephase and polyphase induction and synchronous motors, and both single-phase and polyphase induction motors can have either squirrel-cage or wound rotors The electric motors discussed in this chapter can be catalog or even off-the-shelf distributor models, or they can be custom-designed and built specifically for one customer The most versatile motors are classified as general-purpose, but many custom-built models are essentially variations of general-purpose models with additional features to adapt them for more efficient performance of some specialized task If these motors fill an important applications niche they will be sold to other customers, and if demand for them increases they might become catalog or production models and continue to be made in volume Among the specialized motors available today are agricultural motors, brakemotors, chemical service, compressorduty, explosion-proof, fan and blower, food-processing washdown, pressure washer, and even poultry and woodworking motors

These applications call for differences in starting torque, starting current, horsepower rating, and other parameter such as full-load slip They also call for different dimensions, construction, and materials There are motors with open drip-proof or totally enclosed frames Washdown motors are made to withstand the frequent washing needed to remove spilled food or chemicals Splash-proof motors can resist liquids spilled on them, and explosion-proof motors with completely enclosed frames confine any internal electrical arcing that could ignite fires or set off explosions Electricians and equipment installers run approved wiring to the outlets rated for higher current needed for the motors in washing machines, clothes dryers, and air conditioners, which are equipped with the proper mating plugs They must account for their voltage requirements and wattage and install them in properly rated branch circuits Some building service equipment with motors, such as furnaces, hot-water heaters, air-conditioning systems, fans, and pumps, are permanently wired in branch circuits Most motors in homes and offices are single-phase, fractional-horsepower AC units, but integral-horsepower AC motors power equipment such as elevators and HVAC equipment in high-rise buildings, shopping malls, hospitals, and factories Because of their prominent use, the focus in this chapter is on AC motors and controls The principal types of AC motors are described and their characteristics are compared However, most motors in automobiles, streetcars, electric-powered trains, aircraft, and industrial and military motion-control systems are DC motors Common DC motors are also described in this chapter, and their characteristics are compared Finally, a glossary of motor terms is included at the end of the chapter for ready reference
