Where are the motors windings located at?

In small generators, the field windings are often on the stator, and the armature windings are on the rotor. Most large machines, however, have a rotating field and a stationary armature. A synchronous motor is virtually identical to a synchronous generator. Thus, the armature is the stator and the field is the rotor.

Where is the field winding in an induction machine?

The stator of an induction motor consists of poles carrying supply current to induce a magnetic field that penetrates the rotor. To optimize the distribution of the magnetic field, windings are distributed in slots around the stator, with the magnetic field having the same number of north and south poles.

Do AC motors have windings?

A typical two-phase AC servo-motor has a squirrel cage rotor and a field consisting of two windings: a constant-voltage (AC) main winding. a control-voltage (AC) winding in quadrature (i.e., 90 degrees phase shifted) with the main winding so as to produce a rotating magnetic field.

What are the two windings of an induction motor?

It has a single cage rotor, and its stator has two windings known as main winding and starting winding. Both the windings are displaced 90 degrees in space.

Which type of winding is induction motor?

Explanation: The concentric winding is the most widely used winding. It is also the most flexible winding of the windings used in the single phase induction motor. 10.

Which of the following is the type of winding in induction motor?

The most used winding type for medium-size induction motors is a double layer winding with pitched winding step, for example pitched for two stator slots (Fig. 2). Significant advantage of the aforementioned winding is a smaller mass of inserted copper because of shortest winding-ends.

What is field winding in AC motor?

field winding in Electrical Engineering A field winding is the insulated current-carrying coils on a field magnet that produce the magnetic field needed to excite a generator or motor. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding.

Where field winding and armature windings are housed?

Generally armature winding is housed on stator slots and field winding on rotor slots for Synchronous machine. In DC machine, armature winding is placed in rotor slots and field winding on stator slots. For detail, you are requested to read Construction of DC Machine.

Where are induction motors used?

AC induction motors are the most common electric motors in the world. These simple, reliable and economical motors are found in refrigerators, washing machines and furnaces, as well as conveyors, pumps, winders, wind tunnels and other industrial equipment.

What are the parts of an AC motor?

The main components of an AC motor are the stator, stationary outer drum, and the rotor, the rotating inner portion attached to the motor shaft. The stator and the rotor produce rotating magnetic fields. The winding of the stator that creates the rotating field is created by alternating current.

What is start windings in motor?

A startup winding, also known as the auxiliary winding, is used to create the torque needed to start a single phase induction motor. This winding creates the rotating magnetic field in this type of motor by changing the relationship of the current in relation to the voltage.

What is starting winding and running winding?

In single-phase, the auxiliary winding can be disconnected when the motor has gained speed as only pulsating magnetic field of a single-phase can run motor, that’s why it can be called a starting winding which is not required for continuously running the single-phase motor.

How is an induction motor different from a commutator motor?

By induction motor, we mean that the stator windings induce a current flow in the rotor conductors, like a transformer, unlike a brushed DC commutator motor. An induction motor is composed of a rotor, known as an armature, and a stator containing windings connected to a polyphase energy source as shown in the figure below.

What kind of motor is an alternating current motor?

The alternating current motor that used the phenomena of the electromagnetic induction to produce the current and flux in the rotor to produce torque is recognized as the induction motor. It is also is known as the asynchronous motor.

What kind of rotor is used in an induction motor?

There are two types of the rotor which are used in an induction motor. The first one is the Wound rotor and the other is a squirrel cage rotor. This rotor is known as squirrel cage because its construction is like a squirrel. Its shape is similar to the cylinder which has laminated slots as a conductor.

How does induction motor reduce its staring process construction?

Induction motors are self-starting motors. Which reduces its staring process construction which is needed in other motors. The speed alteration of the induction motor is almost persistent. The speed classically fluctuates merely by an insufficient percent.
