What configuration do the coils of a dual voltage motor utilize for lower voltage?

In a dual voltage motor, the coils are configured in parallel for operation at the lower voltage. This configuration allows for each coil to receive the full voltage, which enables the motor to start and run efficiently at a specified lower voltage.

When connected in parallel, the impedance of each coil is effectively halved, which increases the overall current capacity of the motor without exceeding the voltage rating of each coil. This is essential for motors designed to operate at different voltages, as it enables them to adapt to a specific system's requirements while maintaining the necessary torque and performance characteristics.

The series configuration, in contrast, would increase the total voltage needed to drive the motor, which is not suitable for lower voltage applications. The series/parallel option refers to a more complex setup that is not typically used for dual voltage motors specifically designed for lower voltage operations. An open circuit, by definition, indicates that there is no current flow, which would prevent the motor from operating at all. Thus, the parallel configuration is the most effective for achieving the necessary operational characteristics at lower voltages.
