CHAPTER 11
pages.mtu.eduThe ear-shaped projections in the center are the pole faces, which actually become a north and south pole during operation of the machine. The field coils are mounted behind the ear-shaped projections and provide the magnetomotive force (MMF) required to establish the magnetic field. MMF is the product of current and the number of turns in the ...

CONSTRUCTION TIP Parking lot retrofits can be done in increments, assuming that the existing pole locations will be reused. The costs of trenching to provide power to the poles, foundation for the poles, and the poles themselves can often exceed the cost of the luminaires.

esrmotors.comareas for 4-pole motors. (See Table A footnote.) In this case, NEMA calls for 75 HP in the frame size in which IEC calls for 50 HP. Dropping to a NEMA 326T frame provides the 50 HP needed, if the dimension differences are acceptable. If you need the 364T dimensions, be sure not to damage the drive train or load if using the higher-power motor.
The mathematics of sundials - ed
files.eric.ed.govthe pole would form a circle on the surface of the Earth parallel to the equator. If the circle is divided into 24 equal hour marks, the position of the shadow around the circle would give the time. Sundials based on this principle are called equatorial sundials. In any sundial, the part that casts the shadow is called the gnomon.
