Assignment 21


The following is a partial taxonomy of rotating electrical machines. Electrical machines may
be categorized for analysis purposes into alternating current (ac) or direct current (dc).
Some machines run on ac, some on dc, and some will run on either. An ac machine may
be synchronous or induction. A few examples of electrical machines include large
synchronous motors, small induction motors, universal motors, and permanent magnet
motors. Most motors found in the homes are usually induction machines or universal
motors. Universal motors are typically used in where high speed is needed such as in
blenders or vacuum cleaners. They will run on either “AC” or “DC”. Permanent magnet
motors are frequently used in toys and will work only on dc.
Prepare an object diagram showing how the categories and the machines just described
relate to one another. Use multiple inheritance where it is appropriate to do so.
