Answer Posted / Asheesh Kumar Yadav
The minimum winding resistance for a motor depends on its size, type, and specific design. Here are some general guidelines for common types of motors:nn- Small AC Motors: For single-phase induction motors with ratings up to 1 horsepower (0.75 kW), the minimum winding resistance is typically between 8 ohms and 20 ohms.n- Large AC Motors: For three-phase induction motors, the minimum winding resistance can vary greatly depending on the size and rating of the motor. Generally, for larger motors (e.g., 10 horsepower or more), the minimum winding resistance may be in the range of several ohms to hundreds of ohms.nnIt is essential to consult the manufacturer's specifications for accurate winding resistance information for a particular motor.
