machines incorporating a motor/motors

[Snappy]

Are the following expressions both acceptable if each machine that they sell has a single motor?

1. They sell machines incorporating a highly efficient motor.
2. They sell machines incorporating highly efficient motors.

Have you checked the definition of incorporate (to put or take in (something) as part of a whole; include).
It is very awkward and unnatural. Native speakers would not use this word.

They sell machines that have highly efficient motors.
They sell machines with highly efficient motors.
Each machine has a highly efficient motor.
All of their machines have highly efficient motors.

Thanks. I still have a question.
If I say, "They sell machines that have highly efficient motors," don't people misunderstand that each machine that they sell has more than one motor?
Is it okay to say, "They sell machines that have a highly efficient motor."?

Is it okay to say, "They sell machines that have a highly efficient motor."? The first sentence is more natural.

Thanks, Bhai.

I am still confused. What about the following cases?
1. "They sell machines that have a recently developed motor/recently developed motors."
3. "They sell machines that uses a motor that has/motors that have been recently developed."
