How does an eddy current dynamometer work?
Principle of Working of Eddy Current Dynamometer Eddy Current Dynamometer works on the principle that, “when a conductor moves through a magnetic field, it induces eddy currents (called as local currents). These eddy currents flow in a short circular path around the conductor and are dissipated in the form of heat. ”
What is inductor dynamometer?
It consists of a metal disc or wheel which is rotated in the flux of a magnetic field. 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.
How does dynamometer measure force?
dynamometer, device for measuring mechanical force, or power, transmitted by a rotating shaft. Since power is the product of torque (turning force) and angular speed, all power-measuring dynamometers are essentially torque-measuring devices; the shaft speed is measured separately.
What are the types of dynamometers?
There are two main types of dynamometers, which are both used frequently in the auto industry and in industrial and manufacturing processes. These are chassis dynamometers and engine dynamometers. Chassis dynos measure automobile wheel rotation with computer software in order to determine engine or motor torque.
Which parameters can be measured using a dynamometer?
A dynamometer or “dyno” for short, is a device for simultaneously measuring the torque and rotational speed (RPM) of an engine, motor or other rotating prime mover so that its instantaneous power may be calculated, and usually displayed by the dynamometer itself as kW or bhp.
How does dynamometer measure power?
Where are eddy currents used?
The minor application areas where eddy currents are utilized include use in energy meters, automobile speedometers, induction alternating current (AC) motors, free-fall devices, as a way of detecting coins in vending machines, to increase temperatures uniformly in induction furnaces, and in proximity/displacement …
What are the applications of eddy current dynamometer?
The eddy current dynamometer is applicable to the performance test of internal combustion engine, medium and small power motor, automobile transmission parts, gas turbine, water turbine, engineering machinery, forestry, mining and oil drilling. It can also be used as power absorbing device of other power equipment.
How is torque measured on an eddy current dynamometer?
This torque is measured by a sensor at the end of the arm on the dynamometer. The eddy current dynamometer, as a kind of load, is mainly used to measure the various characteristics of dynamic mechanical test equipment.
Who makes eddy current Dynos?
Time-honored and well-respected manufacturers of eddy current dynamometers, were acquired by Dyne Systems in 2002. Features of Eddy Current Dynos include:
