Q. Show Applications for Synchronous Motors?
With constant-speed operation, power factor control, and high operating efficiency, three-phase synchronous motors are employed in a wide range of applications. An overexcited synchronous motor, known as a synchronous condenser, is used to improve the system power factor. Synchronous motors are used as prime movers of dc generators and variable-frequency ac generators. Typical applications include pumps, compressors, mills, mixers, and crushers. Single-phase reluctance motors find application in such devices as clocks, electric shavers, electric clippers, vibrators, sandpapering machines, and engraving tools. A hysteresis motor is employed for driving high-quality record players and tape recorders, electric clocks, and other timing devices. The horsepower range is up to 1 hp for hysteresis motors, and up to 100 hp for reluctance motors.
For a 45-kVA, three-phase, wye-connected, 220- V synchronous machine at rated armature current, the short-circuit load loss (total for three phases) is 1.80 kWat a temperature of 2
