What is typically true for the resistance and inductance of large medium-voltage motors when measured?

When measuring the resistance and inductance of large medium-voltage motors, it is typically true that these motors exhibit low resistance and high inductance characteristics.

Low resistance in large medium-voltage motors is a result of their construction, which utilizes conductors with substantial cross-sectional areas to minimize losses during operation. This allows for efficient performance as lower resistance translates to reduced energy wasted as heat.

On the other hand, high inductance is observed due to the presence of coils and windings within the motor. Inductance is significantly affected by the motor's design, including the number of turns in the windings and the core material used, both of which contribute to a higher capacity to store energy in the magnetic field when the motor is energized.

In essence, the electrical properties of large medium-voltage motors are designed to minimize resistive losses while optimizing performance through magnetic inductance, making the observation of low resistance and high inductance consistent with their operational characteristics.
