Which of the following motors is usually used in household refrigerators?

D.C. shunt motor
D.
shunt motor B.
Reluctance motor

The correct answer is C. Single phase induction motor (split phase start or induction run motor).

A single phase induction motor is a type of electric motor that uses a single alternating current (AC) supply to produce a rotating magnetic field. The rotating magnetic field induces a current in the rotor, which causes it to rotate. Single phase induction motors are the most common type of motor used in household appliances, such as refrigerators, washing machines, and dryers.

A D.C. shunt motor is a type of electric motor that uses direct current (DC) to power it. The motor has a field winding and an armature winding. The field winding is connected to a DC source, and the armature winding is connected to a commutator. The commutator is a series of metal rings that are connected to the armature winding. The brushes are two metal pieces that are in contact with the commutator. The brushes transfer current from the DC source to the armature winding.

A D.C. series motor is a type of electric motor that uses direct current (DC) to power it. The motor has a field winding and an armature winding. The field winding is connected in series with the armature winding. This means that the current that flows through the field winding also flows through the armature winding. The field winding creates a magnetic field, and the armature winding creates a current that interacts with the magnetic field. This interaction causes the motor to rotate.

A reluctance motor is a type of electric motor that uses the principle of reluctance to produce torque. Reluctance is the tendency of a material to oppose a change in magnetic flux. In a reluctance motor, the rotor is made of a material that has a high reluctance. The stator is made of a material that has a low reluctance. When current flows through the stator windings, it creates a magnetic field. The magnetic field interacts with the rotor, and this interaction causes the rotor to rotate.

Single phase induction motors are the most common type of motor used in household appliances because they are simple, reliable, and efficient. They are also relatively inexpensive to manufacture.
