Why does a car have both a motor and engine?
I don't understand why a car would have both if they both provide rotational energy, unless they just stack? I don't know what's going on.

"Engine" and "motor" are almost the same thing, and when talking about cars are often used interchangeably. However, an engine usually refers to an internal combustion engine (which is gasoline or diesel-powered), while a motor usually refers to an electric motor, as used in electric cars.
My education is in automation and my current job works very heavily with pneumatic systems, so my usable idea of what a motor and engine is are very different from most people familiar with the terms. I would get some seriously strange looks for saying that a compressor engine was bad comparatively.
Typically, people do associate the terms with different forms of power, but they're really the same thing. A motor creates motion using supplied power. That's what a car engine does: it uses the chemical energy in fuel to move pistons.
If I understand correctly about your line of work, this is consistent: the supplied power source is converted to rotational motion in the fans. Your compressor engine is also a motor.
If you have something else that turns the airflow into electricity, then you have a generator there, and will need another motor to make stuff move again.
This is also why hybrids need an electric motor and a gas engine: they have a generator that turns motion into electricity, so they need something that turns electricity back into motion.
