Abstract
An assembly for a gas turbine engine of an aircraft includes a rotational assembly, a starter generator, and a control relay. The starter generator is coupled with the rotational assembly. The starter generator is configured to selectively drive rotation of the rotational assembly. The starter generator includes a motor winding including a first electrical terminal and a second electrical terminal. The control relay includes a switch electrically connected to the first electrical terminal. The switch is positionable in a first contact position and a second contact position, in the first contact position, the first electrical terminal is electrically isolated from the second electrical terminal through the switch. In the second contact position, the first electrical terminal is electrically connected to the second electrical terminal through the switch such that a closed electrical circuit is formed through the motor winding, the first electrical terminal, the second electrical terminal, and the switch.
