Nema C-Face is a type of motor mount. It is used in all sorts of mechanical applications, from car motors to compressors to machine tools. A Nema C-Face mount is a face mount, which means it is attached with bolts that enter threads in the motor face.
The Nema C-Face mount is often used as an adapter of sorts. When a motor requiring a face mount is to be placed in a vehicle designed for another mounting style, a Nema C-Face mount can be used to adapt it to the situation. This allows for different motors to go in different vehicles easily.
A Nema C-Face mount is fastened directly to the motor through bolts that pass through the mount into threads in the motor casing. This allows it to be used in many different situations where a standard mount is not possible.
The Nema C-Face mount secures the motor in place. This insures it doesn't move during operation, which is especially important in motor vehicles moving at high speeds. This mount is considered secure and is one of the most common types of mounts.
