Electrical 2 (DC Generator)

A generator is one kind of electrical machine, and the main function of this machine is to convert

• Electrical to Mechanical Energy
• Mechanical to Electrical Energy
• Mecahnical to heat energy
• None

Generator Works on the Principle of

• Fleming Left hand rule
• Fleming right hand rule
• Faraday Law of EMI
• None

The ___________ acts as the outer cover of a DC motor and it is also known as the frame.

• Pole
• Pole core
• Yoke
• Armature

The yoke is an iron body, made up of low reluctance magnetic material such as

• cast iron
• silicon steel,
• rolled steel
• all the above

The main Purpose of Yoke is _______________

• To provides mechanical protection to the outer parts of the machine
• It Provides low reluctance path for the magnetic flux
• Both A & B
• None

_____________ Produces the Magnetic Flux in the DC generator

• Yoke
• Pole
• Armature
• Commutator

The Coils around the Pole is Called

• Field Winding
• Armature Winding
• Both A & B
• None

________________converts alternating torque into unidirectional torque produced in the armature.

• Armmature
• Commutator
• Carbon Brush
• Yoke

Speed (N) is measured by ------

• second
• KM
• RPM
• Minutes

Compound wound generators have

• shunt winding
• series & shunt winding
• series winding
• None
