What feature makes squirrel cage induction motors economically favorable?

• A. High maintenance requirements
• B. Complex construction
• C. No brushes or additional components
• D. Use of rare materials

Answer: (C)

Squirrel cage induction motors are favored for their simplicity and durability. The absence of brushes or additional components means that these motors have fewer parts that can wear out or require maintenance. This attribute leads to lower operational costs over time since they do not necessitate regular replacements or significant maintenance procedures associated with brushes and commutators, which are common in other types of motors. Moreover, the straightforward design allows for efficient manufacturing processes, which can further reduce costs. The robust construction of squirrel cage induction motors contributes to their reliability in a variety of applications, making them an ideal choice for many industrial and commercial settings. The efficiency and low upkeep requirements enhance their appeal for widespread use, driving down lifetime costs significantly compared to other motor types that involve more complex components.
