1. Why does the AC Washer Motor generate shaft current?
The shaft of the motor---bearing---the current in the base circuit is called the shaft current.
Reasons for shaft current generation:
(1) Asymmetry of the magnetic field;
(2) There are harmonics in the supply current;
(3) The manufacturing and installation are not good, and the air gap is not uniform due to the eccentricity of the...
When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions.
For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the difference between basic types of motors in...
