SACA Motor Control Practice Exam

In dual-voltage motors, the ability to operate effectively at two different voltage levels allows for flexibility in connecting to different power sources. The correct voltage levels in a dual-voltage motor setup typically involve configurations that are widely used in industrial and commercial applications.

The pairing of 240V and 600V is a common configuration found in industrial settings, where machinery can alternate between these voltages depending on the system requirements or power supply availability. This versatility is advantageous for ensuring the motor can draw power from different sources or be compatible with varying electrical systems.

The other options present voltage combinations that either do not align with common industrial practices or do not typically represent the configurations used for dual-voltage motors. For instance, the other pairs either exceed typical operating ranges for certain motor designs or include voltage levels that are not typically used in tandem for dual-voltage applications. Therefore, the selection of 240V and 600V accurately reflects valid and practical voltage options for dual-voltage motors.
