Q:

What are the characteristics of a DC Shunt Motor?

A:

DC shunt motors operate using direct current and have their armature and field winding connected in a parallel configuration. DC shunt motors are similar to other types of DC motors in that they include the same components: They  come with a commutator, an armature and field winding.

There are three major types of DC motors: Series motors, compound motors and shunt motors.  A DC shunt motor derives its name from the way it is wired €” the armature is connected in parallel (shunt) with the field coil. The interaction between the magnetic field of the field coil and that of the armature is what causes the motor to rotate.  This configuration  provides an independent path for  current flow, which allows for more efficient speed regulation. The speed of a DC shunt motor can be regulated by either varying the amount of current supplied to the field coil or varying the amount that flows through the armature.

DC shunt motors are more commonly used in automotive and industrial applications that require precise speed and torque control. Installing a DC shunt motor is relatively easy. However, special care needs to be given to ensure that the load shaft and motor shaft are properly aligned to prevent putting too much stress on the armature.

    What is the function of a cylinder head?

    A:

    An internal combustion engine's cylinder head performs several functions including housing the exhaust and intake valves, the fuel injector and necessary linkages, and passages for the fuel and air mixture. In water-cooled engines, the cylinder head also contains integral ducts and passages for the engine's coolant to facilitate the transfer of excess heat away from the head and, therefore, the engine in general.

    What is a centrifugal supercharger?

    A:

    A centrifugal supercharger is a type of air compressor that employs centrifugal energy to pump additional oxygen into an internal combustion engine. By increasing the airflow, the supercharger helps the engine burn more fuel, which increases its power output.
