How can a split-phase induction motor be connected for a 230-volt operation? What about for a 115-volt operation?
The schematic diagram of a split-phase induction motor connected for a 230-volt operation involves connecting the two running windings in series with the line voltage of 230 volts. The starting winding is also connected to the line voltage of 230 volts. On the other hand, to connect the split-phase induction motor for a 115-volt operation, the two running windings must be connected in parallel, and the starting winding must be connected in series with a capacitor. Let's dive deeper into the explanation below.
Schematic Diagram of Split-Phase Induction Motor Connected for a 230-Volt Operation
Explanation:
A split-phase induction motor is designed to start by itself but needs a starting circuit for running. It consists of two windings: a starting winding and a running winding. The starting winding provides the motor with the initial torque needed for starting, while the running winding generates the motor's running torque.

Schematic Connection Diagram of Split-Phase Induction Motor Connected for a 115-Volt Operation
Explanation:
To connect a split-phase induction motor for a 115-volt operation, the two running windings must be connected in parallel, and the starting winding must be connected in series with a capacitor. This configuration allows the motor to operate effectively at the lower voltage of 115 volts.
Therefore, the main answer to the given problem is as follows:
