Stator Motor

And repelled to the magnetic properties of the stator element thus creating torque for a DC motor a

What is a stator and how it works?

The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.

What is stator and rotor in motor?

The rotor is the rotating part of a machine. In electrical motors or generators, the whole linear synchronously rotating part of the machine is termed the rotor. The stator is the non-moving, fixed counterpart in a machine.

Why is it called a stator?

A stator is the static part of rotary electromagnetic devices such as electric motors, alternators, and generators. It represents one of the two primary components of the device, the other being the moving rotor that supplies the working output.

What is the advantage of stator?

Stator laminations reduce eddy current by insulating the core. Thin silicon steel plates are stacked on top of one another around the center, preventing eddy current flow. With the eddy current reduced, the stator core can maintain constant power, keeping your motor running.

What are the 4 types of motors?

They are:

• Series DC Motor.
• Shunt/Parallel DC Motor.
• Compound DC Motors.
• Permanent Magnet DC Motor.

Why stator is used in DC motor?

In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate. A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil.

What is the difference between motor and stator?

The stator and rotor both are the parts of the electrical motor. The significant difference between the rotor and the stator is that the rotor is the rotating part of the motor whereas the stator is the stationary part of the motor.

What is a stator also known as?

The stator is the stationary part of rotary electromagnetic devices like the alternator, electric motor, or generator. You might hear the term “stator” used interchangeably with “alternator” or “generator,” even though it only makes up a part of those larger devices.

What is stator made of?

The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.

What is stator and armature?

The armature provides housing and support to the armature winding. In electrical machines, the magnetic field is generated by a permanent magnet or electromagnet. The armature winding interacts with the magnetic field formed in the air gap. The stator can be a rotating part (rotor) or stationary part (stator).

Why is stator used in DC motor?

In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate. A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil.

Why armature is used as stator?

Greater amount of Copper can be accommodated if the Slot / Tooth is deeper and strong enough. If the Armature would have been on Rotor then Slot / Tooth would have been narrow and weaker. Thus armature on the Stator allows stronger and deeper Slot / Tooth.

Why synchronous motor is need a stator?

One advantage of the synchronous motor is that the magnetic field of the machine can be produced by the direct current in the field winding, so that the stator windings need to provide only a power component of current in phase with the applied stator voltage—i.e., the motor can operate at unity power factor.

Why do induction motors need stators?

A stator is needed for an induction motor (three phase type) in order to limit the starting current. In a three phase induction motor, the rotor induced emf is proportional to the slip (it is the relative speed between stator and rotor) of the induction motor. This rotor emf drives the current through the rotor.
