ASME Y14.44-2008 [1] and IEEE 315-1975 [2] define how to reference and annotate components of electronic devices. It breaks down a system into units, and then any number of sub-assemblies. The unit is the highest level of demarcation in a system and is always a numeral.
Cross-section of switched reluctance machine with 6 stator and 4 rotor poles. Notice the concentrated windings on the stator poles. A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. The rotor does not have any windings. It generates torque through magnetic reluctance.
Other classifications are considering the windings totally concentrated in one coil per phase or partially concentrated in two poles per phase (i.e., single-sided) or four poles per phase (double-sided). [2] Switched Reluctance motors have been used extensively in clocks and phonograph turntables before, but nowadays, with the rising emphasis ...
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
Other types of resolver are multipole resolvers. They have 2p poles (p pole pairs), and thus can deliver p cycles in one rotation of the rotor: the electrical angle is p times the mechanical angle. Some types of resolvers include both types, with the 2-pole windings used for absolute position and the multipole windings for accurate position.
A winding on a motor or generator to improve commutation at heavy load. computed tomography Production of images of a cross-section through an object by multiple X-ray measurements processed in a computer. computer engineering The profession of designing computers. computer hardware That part of a computer system with physical existence.
The motor has a stator and a rotor but there is no electrical connection between the two and the rotor current is generated by induction.The rotor winding is connected to a commutator which is in contact with a short-circuited pair of brushes which can be moved to change their angular position relative to an imaginary line drawn through the axis of the stator.
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 ...
