Which of the pictured motors is a square core shaded pole motor used to drive very small electrical loads and is non-reversible? Illustration EL-0208
AI Explanation
The correct answer is B.
The square core shaded pole motor is a type of small, non-reversible electric motor commonly used to drive very small electrical loads. This motor design is typically found in appliances, fans, and other low-power devices. The illustration EL-0208 shows several different motor types, and option B depicts the characteristic square core and single-phase design of a shaded pole motor.
The other options (A, C, and D) represent different motor types that do not match the specific characteristics of a square core shaded pole motor as described in the question.
