The reason the Code uses the term instead of motor is that, in many instances, the motor is inside an enclosure and is out of sight until an access panel is removed.

Motor location

Explanation:

Due to the fact that to locate the motor, it is mandatory to remove the access panel for you to even see the motor, because it is usually located inside an enclosure which is out of sight, the NEC uses the term motor location, instead of just saying motor. This is to mean that the motor can be located in the enclosure, but the enclosure itself is not really the motor.

Motor location

Explanation:

The national electrical code, NEC, is a collection codes that describes a standard of electrical components and mechanical components controlled using codes.

The NEC uses the code motion location on a hidden motor, describing the location of the motor of the machine rather than the motor component itself. It is considered because in many instances, the motor is inside an enclosed or hidden area and can only be seen when the access panel is opened or removed.
