Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFIn a long shunt compound motor, if the shunt field winding gets open-circuited, then:
- The shunt field winding provides the main field flux.
- If it gets open-circuited, the field flux will drop drastically.
- The motor will then behave like a series motor, relying only on the series field winding for flux.
- In a series motor, as the load decreases, the speed increases significantly, which may lead to dangerous overspeeding.
