MMET 301 Quizzes With Complete
Solutions
AC motor stators contain windings with two or more magnetic poles per
| | | | | | | | | | |
phase. - CORRECT ANSWER✔✔-True
| | | |
AC induction motor rotors consist of a laminated cylinder with plastic
| | | | | | | | | | |
bars in slots around the outer part of the cylinder. - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-False
A typical DC motor option is a: - CORRECT ANSWER✔✔-Space Heater,
| | | | | | | | | | |
Tachometer, Blower |
AC motor stators contain windings with two or more poles per phase.
| | | | | | | | | | | |
What type of poles are these? - CORRECT ANSWER✔✔-Magnetic
| | | | | | | |
What type of motor consists of two basic types including brush and
| | | | | | | | | | | |
brushless? - CORRECT ANSWER✔✔-DC | | |
The definition of torque is: - CORRECT ANSWER✔✔-The tendency of a
| | | | | | | | | | |
body to rotate | |
, If we are given the torque and the rpm of a shaft, then we can calculate:
| | | | | | | | | | | | | | |
|- CORRECT ANSWER✔✔-The HP output of the shaft
| | | | | | |
A 2 HP motor is attached to a gearbox by a coupling. The motor shaft
| | | | | | | | | | | | | | |
(and therefore the input shaft of the gearbox) turns at 1,800 revolutions
| | | | | | | | | | |
per minute. We observe that the output shaft of the gearbox is turning
| | | | | | | | | | | | | |
at 60 revolutions per minute, and is producing 1 HP of unusable power.
| | | | | | | | | | | | |
From this data, we can conclude that the efficiency of the gearbox is: -
| | | | | | | | | | | | | |
CORRECT ANSWER✔✔-50% efficient | |
What are the two components of torque? - CORRECT ANSWER✔✔-F
| | | | | | | | | |
and D |
Power and rpm are both what? - CORRECT ANSWER✔✔-Rates
| | | | | | | |
What are the basic criteria for "work?" - CORRECT ANSWER✔✔-Force
| | | | | | | | | |
causing motion |
Electric motors operate on the principle that a force acts on a conductor
| | | | | | | | | | | |
when it carries current in a magnetic field. - CORRECT ANSWER✔✔-T
| | | | | | | | | | |
Another name for a 3-phase motor is: - CORRECT ANSWER✔✔-
| | | | | | | | |
Polyphase
