Rotating Machinery
- correct answer Any machine that has a spinning, or rotating shaft and uses electricity as the input or
output
motor and generator
- correct answer the two categories of rotating machinery
Motor
- correct answer uses an electrical input and converts it to a rotating mechanical output
generator
- correct answer uses a rotating mechanical input and convert it to an electrical output
CMEF
- correct answer Voltage produced in a motor that opposes the applied voltage
Stepper
- correct answer Type incremental motor that uses digital pulses
Analog
- correct answer Type of incremental motor that uses specific magnitudes of voltage
Torque
- correct answer The twisting force that rotates the shaft of a motor or generator
, greatest
- correct answer Torque is _____________ in a locked condition.
33,000 ft-Ib/ min or 550 ft-Ib/sec
- correct answer Horsepower is the power rate corresponding to the rate of conversion per min or per
sec
