When a product is being engineered and designed, it is important to determine the parameters of its use, which can be completed with a variety of testing instruments. In the case of engines, chassis, and rotating devices, it is important to know the speed and torque that they can endure with low risk to engineers. An AC dynamometer is a device that can provide the proper data safely and accurately.
What is an AC Dynamometer?
An AC dynamometer offers a convenient snapshot of performance in order to develop a comparison between actual execution and the established design specifications. In an attempt to improve their products as well as test them sufficiently prior to their being introduced to the market, manufacturers are ramping up their efforts to perfect their products by sophisticated testing.
The use of AC dynamometers has been a major step in the advancement and improvement of products. The purpose of an AC dynamometer is to measure the RPMs and torque an engine or electronic device can withstand by making a closed loop connection to the system to be tested using various industrial interfaces.
The testing unit provides controls of temperature, pressure, speed, and torque levels to monitor the specific element to be tested. The standard AC dynamometer unit has an AC induction motor, a torque sensor, some form of base, a flange connected to power machinery, AC converter system, and dynamometer measuring instrument.
Dynamometers have a very high accuracy rating of 90% and above. This single factor adds to their dependability and the reliability of the data, which is valuable in regard to a motor’s capabilities.
AC Dynamometer Applications
Testing has become a necessity for any type of electronic or gas motor. It is irrelevant whether it is an electric tool, large electrical motor, diesel engine, marine engine, or powertrain part, testing is an essential part of determining quality, applicability, performance, and endurance. The benefit of an AC Dynamometer is its being ecologically friendly and environmentally safe.
The first industry to take advantage of the use of a dynamometer is auto production. By using a dynamometer, they can save time, get accurate instant data, and remove the need for complex and complicated testing. From the first dynamometer designed to measure the capabilities of horses, to today’s more advanced versions, dynamometers have been a major improvement in engine testing methods.
Uses of an AC Dynamometer
Though dynamometers are mainly used to test engines, they do have several other testing functions. Due to concerns regarding environmental pollution, dynamometers are able to simulate road conditions to measure the number of emissions produced by an engine.
Aside from their use for testing engines, dynamometers can be used by the medical industry to measure the stability of a patient’s hand and grip function. They have become a vital instrument for rehabilitation, kinesiology, and ergonomic purposes.
