It's a good choice. I highly recommend this 3d model.

It is a professional model for professional graphic designers.
Very well made with a high amount of detail. Very realistic modeling. Ideal model.

Modeled
armature - stator, axle, rotor, windings, commutator
bearings

cables, connectors, terminal

and other parts

Model ideal for professional graphic;
animation, design visualization, presentation - newspapers, technical magazine, advertising, high resolution film, technical demonstrations, etc.

The diagram is included. The diagram has modeled words.

Good luck in Your professional project.
