What is the difference between stator and rotor?

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 the purpose of the rotor stator system?

In an electric motor, the stator provides a magnetic field that drives the rotating armature; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.

What is the rotor of a motor?

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor’s axis.

What does a stator?

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 the meaning of a rotor?

Definition of rotor 1a : a part that revolves in a stationary part a brake rotor. b : the rotating member of an electrical machine. 2 : an assembly of rotating blades that supplies lift or stability for a rotorcraft.

What is rotor in turbine?

rotor, rotor coil – the rotating armature of a motor or generator. stator, stator coil – mechanical device consisting of the stationary part of a motor or generator in or around which the rotor revolves. steam turbine – turbine in which steam strikes blades and makes them turn.

What is a compressor rotor?

An axial flow compressor has two basic elements – a rotor and a stator. The rotor has blades that are fixed on a spindle. These blades impel air rearward in the same way a propeller does. They are basically small airfoils. The rotor turns at a high speed and impels the air through a series of stages.

What is rotor stator homogenizer?

Rotor-stator homogenizers consist of a fast-spinning inner rotor with a stationary outer sheath (stator) to homogenize samples through mechanical tearing, shear fluid forces, and / or cavitation (the rapid forming and collapsing of bubbles).

What is a stator in English?

stator in British English 1. the stationary part of a rotary machine or device, esp of a motor or generator. 2. a system of nonrotating, radially arranged parts within a rotating assembly, esp the fixed blades of an axial flow compressor in a gas turbine. Compare rotor (sense 1)

What is rotor force?

The resultant force imparted by a lifting rotor. It can be broken into lift, drag, and thrust—all of which are perpendicular to the disc.

What type of thermistor is used in DC motor?

In DC motors, PTC thermistor sensors are increasingly used instead of microtherms, which are described in the section above. The rated response temperatures (RRT), which are commonly selected for the various classes of insulation on electric motors, are summarized in the table in Figure 3.

Where are thermistors located in a circuit?

By correct positioning, thermistors can be located close to the thermally critical areas, or hot-spots, of the winding, where they closely track the copper temperature with a certain time lag, depending on the size of the thermistors and how well they are installed in the winding.

What is the purpose of a PTC thermistor?

In AC variable speed drives, PTC thermistors are commonly used to protect the AC squirrel cage motor fed from inverters. Many modern AC converters have a thermistor protection unit built into the converter, avoiding the requirement for a separate thermistor protection relay. In DC motors,…

What are the advantages of thermometer in power system?

Their low thermal inertia gives rapid and accurate response to winding temperature changes. They measure temperature directly irrespective of how these temperatures are initiated. They can be used to detect overload conditions in motors driven by frequency converters.
