Measuring ohms when assessing the performance of a motor indicates the resistance within the motor's windings. Resistance is a fundamental property that affects how electrical current flows through the motor. By measuring resistance, you can determine if there are any issues, such as short circuits or open coils, that could impact the motor's operation.

Resistance values help technicians understand the condition of the motor; for example, unusually high resistance may indicate damage or material degradation, while very low resistance could suggest a short circuit. In contrast, measurements related to power output, current draw, and voltage levels pertain to different aspects of electrical performance but do not directly relate to the resistance of the windings themselves. Thus, understanding the resistance allows for effective troubleshooting and maintenance of the motor.
