- Of Construction Of Machines
Like any other rotating electrical machine, a synchronous machine (generator or motor) has two essential parts namely, Stator − It is a stationary part of the machine and carries the armature winding.. Rotor − It is the rotating part of the machine. The rotor of a synchronous machine produces the main field flux.

These machines can be operated by one person and are used for various tasks on a construction site. As the name implies, heavy machinery pertains to larger machines designed for tougher tasks. Typically, once a piece of equipment weighs more than 5,000 pounds it's classified as heavy construction machinery.

Construction Parts of the machine. It consists of a Yoke, pole core, pole shoe, armature core, commutator, brushes, bearings, and fan. The yoke is used for the protection of the device from outer environmental issues. It is used as a shield to protect the inner parts of the machine. It provides mechanical support to the inner parts of the device.

It is the outer body of the motor. Its main function is to support the stator core and to protect the inner parts of the machine. For small machines, the outer frame is casted, but for the large machine, it is fabricated. The figure below shows the stator construction. Stator Core. The stator core is built of high-grade silicon steel stampings.
