What happens when motor coupled with genarator?

When a motor is coupled with a generator, the motor converts electrical energy into mechanical energy to drive the generator, which in turn converts mechanical energy back into electrical energy. This setup is often used in applications like regenerative braking, where the energy from the motor can be captured and reused. Additionally, the generator can provide power back to the motor, creating a closed-loop system that improves overall efficiency. However, energy losses due to heat and friction will occur in both components.
