Can an alternator run an electric motor?

The alternator will supply the power to the motor which will get less than it needs to run full, which will provide less power to the alternator then giving even less power to the motor, the cycle will keep going (depending on how much momentum it has and how fast it was going) until friction takes over and stops the …

Can an alternator power an electric motor?
