The winding resistance in a motor should be within what range to ensure proper operation?

• A. 0-5 ohms
• B. 5-10 ohms
• C. 10-20 ohms
• D. 20-30 ohms

Answer: (A)

For a motor to operate efficiently, the winding resistance needs to be within a certain range that facilitates proper current flow while minimizing energy losses. When the winding resistance is between 0 and 5 ohms, it generally indicates a well-functioning motor with low resistance, which allows for optimal current to flow through the windings and generates the necessary magnetic fields for operation. Low resistance in motor windings reduces heat generation and energy waste, ensuring that the motor performs effectively without overheating. Resistance values higher than this range may indicate potential issues within the motor, such as winding insulation deterioration or other possibilities that could impede the electrical flow and subsequently affect the motor's performance and lifespan. Thus, maintaining the winding resistance within the 0-5 ohm range is crucial for ensuring smooth operation, efficiency, and reliability of the motor.
