One example is the rotors of electric motors (rotor winding technology, special form of the successive winding method): The wire is held by a clip fixed to the machine during the component change. Since the rotors often consist of heavy, punch-packed metal sheets, the flyer winding technology is of particular advantage in this regard.
As the motor accelerates, the slip frequency decreases and induced current flows at greater depths in the winding. By tapering the profile of the rotor bars to vary their resistance at different depths, or by constructing a double squirrel cage, with a combination of high and low impedance rotor in parallel the motor can be arranged to produce ...
Regal Rexnord Corporation is a manufacturer of electric motors and power transmission components based in Milwaukee, Wisconsin.The company has manufacturing, sales, and service facilities throughout the United States, Canada, Mexico, Europe and Asia, with about 29,000 employees.
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.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1] The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors .
