Frame numbers are not intended to indicate electrical
characteristics such as horsepower. However, as a frame number
becomes higher so in general does the physical size of the motor
and the horsepower. There are many motors of the same horsepower
built in different frames. NEMA (National Electrical Manufacturers
Association) frame size refers to mounting only and has no direct
bearing on the motor body diameter. In any standard frame number
designation there are either two or three numbers. Typical examples
are frame numbers 48, 56, 145, and 215.
Theframe number relates to the “D” dimension (distance from center
of shaft to center bottom of mount). For example, in the two-digit
56 frame, the“D” dimension is 31/2”, 56 divided by 16 = 31/2”. For
the “D” dimension of a three-digit frame number, consider only the
first two digits and use the divisor 4. In frame number 145, for
example, the first two digits divided by the constant 4 is equal to
the “D” dimension. 14 divided by 4 = 31/2”.Similarly, the “D”
dimension of a 213 frame motor is 51/4”, 21 divided by 4 = 51/4”.
What would we have to do in order to reverse the rotation of this
three-phase induction motor?
Explain why this special winding is necessary for the motor to
start, and also why there is a capacitor connected in series with
this start winding. What would happen if the start switch,
capacitor, or start winding were to fail open?
