Eddy Current Dynamometer Construction
Eddy Current Dynamometer Construction. It rotates inside a smooth cast iron stator. Since such magnetic flux is generated and the rotor cuts off these magnetic fluxes, the eddy current opposite to the change.
The construction comprises of a thin spoked steel rotor revolving in a casing that houses. The power absorbed by the dynamometer is. Dry friction dynamometers are the oldest kind, and consist of some sort of mechanical breaking device, often a belt or frictional “shoe” which rubs a rotating hub or shaft.
An Eddy Current Dynamometer (Ec Dyno) Is The Most Popular Type Of Dynamometer Used In Chassis Dyno Construction.
It comprises a stator with some electromagnets and a rotor disc coupled with the engine’s output shaft made of steel or copper. The field if produced by field elements or coils is excited by an external source and attached to the dynamometer housing which is mounted in trunnion bearings. The construction of the eddy current dynamometer is as per the above diagram in which the part of the stator is outside and the winding is properly inserted in the part of the stator slot.
In This Video We Will Learn About Construction And Working Of Eddy Current Dynamometer In Theory Of Machine Element For Mechanical Engineering Students.
Power absorbers are available in a wide range of torque and speed specifications. In a dry gap unit, the only resistance to movement of the rotor is that of bearing friction and the small effect of windage. A schematic of the dynamometer is shown below.
Construction Working Of Eddy Current Dynamometer I Hope You All Have Understood This.
It is one of a range of. 4.0 dynamometer operation and construction the dynamometer consists of a shaft/rotor assembly mounted within a casing supported on a rigid baseplate. This style of dynamometer produces braking torque using the principle of eddy currents induced in a rotating metallic disk, immersed in a magnetic field.
All Type Eddy Current Dynamometers Can Be Connected To Both Open As Well As Closed Cooling Water Circuits.
Dry friction dynamometers are the oldest kind, and consist of some sort of mechanical breaking device, often a belt or frictional “shoe” which rubs a rotating hub or shaft. An eddy current dynamometer uses an electric core moving across a magnetic field to produce. The powerlink eddy current dynamometer measures the torque and power of the prime mover (motor or engine).
Supply From An External Source.
Please review the absorber models below and ask your. Powermag's continuing investment in high quality production, inspection, testing and customer service ensures that powermag will continue to be the leader in eddy current dynamometers well into the future. It consists of a stator on which are fitted a number of electromagnets and a rotor disc made of copper or steel and coupled to the output shaft of the engine.
