An engine start system for an aircraft includes a first variable frequency start generator (VFSG) including a first exciter and a first stator, a second VFSG including a second exciter and a second stator, a first motor controller and a second motor controller, and a switching system. The switching system is configured to operatively connect the first motor controller to the first stator or the second exciter and operatively connect the second motor controller to the first exciter or the second stator. In a first mode of operation, the first motor controller is operatively connected to the second exciter, the second motor controller is operatively connected to the second stator, the first VFSG generates power, the first motor controller provides a first controlled voltage and frequency to the second exciter, and the second motor controller provides a second controlled voltage and frequency to the second stator.
