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?
