Rotor (lower left) and stator (upper right) of an electric motor Stator of a 3-phase AC-motor Stator of a brushless DC motor from computer cooler fan.. The stator is the stationary part of a rotary system, [1] found in electric generators, electric motors, sirens, mud motors, or biological rotors (such as bacterial flagella or ATP synthase).
A washing machine (laundry machine, clothes washer, washer, or simply wash) is a machine designed to launder clothing. The term is mostly applied to machines that use water. Other ways of doing laundry include dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) and ultrasonic cleaning.
During a normal cycle, most Whirlpool-built wig-wag equipped washers will fill, start the motor, then engage the wash solenoid. Upon completion of the wash mode, the wash (agitate) solenoid will be turned off, which will allow the pump to drain the tub. After a minute or two, the timer will then engage the spin wig-wag which will cause the ...
A DC motor consists of two parts: a rotor and a stator. [3] The stator consists of field windings while the rotor (also called the armature) consists of an armature winding. [4] When both the armature and the field windings are excited by a DC supply, current flows through the windings and a magnetic flux proportional to the current is produced ...
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. [1] An induction motor therefore needs no electrical connections to the rotor.
The faster the rotor spins, the further this degree of field distortion. Because a motor or generator operates most efficiently with the rotor field at right angles to the stator field, it is necessary to either retard or advance the brush position to put the rotor's field into the correct position to be at a right angle to the distorted field.
The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. [1] It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. It is often referred to as an AC series motor.
Diagram of the squirrel-cage (showing only three laminations) The motor rotor shape is a cylinder mounted on a shaft. Internally it contains longitudinal conductive bars (usually made of aluminium or copper) set into grooves and connected at both ends by shorting rings forming a cage-like shape.
