How to Select the Proper Engine Dynamometer Water Brake, Eddy Current and AC Engine Dynamometers Selecting any SuperFlow Engine Dynamometer, whether it be water brake, eddy current or alternating current (AC) motor load has the same general guidelines and typically comes down to four main factors:. Dynamometers (Dynos) Offering Precise, Robust and Repeatable Testing. Factor Pro Eddy Current Dynamometer At Flying Eagle Cycle we are able to dyno tune motorcycles up to 95" wheel bases. Typically air-cooled, there are water-cooled versions of the dynamometer used primarily for very high horsepower or high-torque applications. In this paper Eddy current dyna-mometers are used to measure speed & torque. This causes current to flow within the metal plate and thus opposing the already existing magnetic field (Lenz's law). Pontiac, IL 61764 (815). Eddy Current Dynamometer can use for testing diesel engine, gasoline engine, generator’s power output, fuel consumption, torque, and so on. Eddy Current Dynamometer. The 4x2 loading facility (eddy current brake) can be added to the standard inertia dynamometer which enables the user to either put a fixed load on the brake or to hold the vehicle at a certain rpm, as well as perform a controlled sweep test (ramp test), where the speed is gradually increased while the power and sensor readings are recorded. When the rotor is rotated, an eddy current is produced because of a magnetic flux set up by field current in the electromagnet. The engine is a small compact free turbine engine originally Model Number JFS100 manufactured by Allied Signal Inc. Its rugged and rigid design of Power absorbing. Dynamometer (aka rolling-road, dyno or Leistungpruefstand) is a mechanical device for measuring power and torque of a car, bike, truck or even an agricultural machine. doc • V4 • 2001-05-01 C O N T E N T S 1. An eddy current dynamometer (EC dyno) is the most popular type of dynamometer used in chassis dyno construction. Inventories will vary, depending on what we have acquired and have available. Dynamometer Type Wattmeter Principle: If two coils are connected such that, current proportional to the load voltage, flows through one coil and current proportional to the load current, flows through another coil, the meter can be calibrated directly in watts. We offer controllers for most any type of absorber (brake) dyno, electric Eddy Current dynos, dynos with hydraulic pumps for a brake, or water brake dynos. In fact, anything that rotates and has load applied can generally be tested with a dynamometer. Focus on the test requirement of AMT test bench, a fuzzy logic controller was proposed to control the loading force for the flat-straight road working. Sluice Gate Type Hydraulic Dynamometers, Air Gap Eddy Current Dynamometers, Engine And Dynamometers Controllers, Manufacturer, Supplier, Exporter, Kolhapur, Maharashtra, India. The dynamometers have low inertia as a result of small rotor diameter. For the size, a water brake dynamometer is generally economical in comparison to an electric dynamometer. An eddy current dyno has a limit to the maximum power it can handle. Engine Test Stand, Engine Test Bench, Engine Dynamometer manufacturer / supplier in China, offering Dw100 Engine Test Bench Eddy Current Dynamometers Engine Dynamometers- Test Equipment, Chassis Dyno for Sale Dyno Test Dyno Testing Machine, Chassis Dynamometer for Car and Motorcycle Dyno Machine Made in China and so on. It is basically an eddy. Closed loop control systems ensure accurate and repeatable drives on the dynamometer. Check line voltage before operation on any dynamometer that uses AC input power. Suitable for high speed series motor and high speed AC power tool's FFU test,temperature rise test. In the eddy current dynamometer setup, a clever device is used to directly measure torque. please contact us today and we will work with you to provide an optimal inertia dyno solution. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. Model Max Absorbed Power Max Braking Torque Constant Torque Nm - rpm Range Constant Power KW - rpm Range Moment of Inertia Water Flow KW HP Nm RPM RPM KgM. to the right, mass m is attached to a wheel of radius R, and is lifted up as torque T applied is applied (counterclockwise) to the wheel. Eddy current dyno packages are available turn key, mechanical only or absorber only. The narrow yet durable design, small footprint, and the exclusive material and construction technique ensures many years of service. The Froude Hofmann AG150HS eddy current dynamometer is rated at 150 kW (200 bhp) and has a maximum operating speed of 12,000 rpm. The dynamometers produced and manufactured according to the proprietary techniques of ZOLLNER GMBH in Germany, have advantages of low inertia, high accuracy and stability, simple structure, convenient maintenance, complete series, wide use, automation in operation.
