EDDY CURRENT DYNAMOMETERS

The Air Gap (AG) range of Eddy Current Dynamometers has been designed to be compact, robust and to allow easy maintenance. The narrow yet durable design, small footprint, and the exclusive material and construction technique ensures many years of service. These units are bi-directional, fitted with 40,000-hour bearings and extremely accurate (0.25% Full Scale Torque). 

Each eddy current dynamometer is fitted with oil injected half couplings at either end of a non-magnetic stainless steel shaft which is supported in grease lubricated, deep groove ball bearings. The non-magnetic shaft means negligible magnetic field dispersion. The dynamometer casing houses twin magnetizing coils that produce a retarding controllable magnetic field that resists the applied torque. Heat generated in this process is dissipated by cooling water

FROUDE INVENTED THE WATER BRAKE DYNAMOMETERS

testingindonesia.com The Froude F Range Hydraulic dynamometers (also referred to as water brakes) have been designed to be compact, robust and to allow easy maintenance. Some of these models are available with a streamlined, fabricated base. This base is not only ultra durable due to the powder coating process, but also offers flexibility with water inlet/outlet placement and lifting eye locations. These engine dynos are fitted with two half couplings which, with the rotor, are oil injected onto the shaft. The standard machines run in grease lubricated rolling element bearings. The hydraulic dynamometer working compartment consists of special semi-circular shaped vanes cast into stainless steel rotor and stators. Water flowing in a toroidal vortex pattern around these vanes creates a torque reaction through the dynamometer casing which is resisted and measured by a precision load cell. The dynamometer load is controlled by a 'butterfly' water outlet valve, oper

The Froude AC dynamometer has been specifically designed for the testing of gasoline and diesel engines in R & D and Quality Audit applications.   Low inertia AC motor with standard speed ranges from 3,500 rpm to 10,000 rpm Standard torque hub measurement accuracy is +/-0.2% of the full rated torque of the dynamometer Speed is measured to an accuracy of +/- 1 rpm testingindonesia.com      SPESIFIKASI       Description The AC dynamometer is constructed using a low inertia AC motor especially designed for engine test applications mounted on a substantial fabricated baseframe. On foot mounted versions torque is measured using an in-line torque hub. For trunnion mounted machines a precision strain gauge load cell is used. As an option both versions can include an integrated jackshaft that provides additional overhung load capacity for the engine drive shaft.                 Froude AC       Dynamometer Heat gen

EDDY CURRENT ENGINE DYNAMOMETERS

Overview testingindonesia.com SuperFlow offers a broad selection of technologically advanced eddy current absorbers which are ideal for precise engine testing. Low minimum load capabilities allow testing of very small engines, or larger engines running at very light loads and high speeds. Heat is dissipated by cooling water flowing through the stationary portion of the absorber. Rotating water seals have been eliminated. Bearings are pre-lubricated and rated for 5,000 hours of operation between servicing. Standard commercial load cells measure reaction torque for either direction of rotation. The double-ended main shaft may be fitted with a starter motor or used for dual engine connection. Speed is measured by a 60-tooth gear and hall effect sensor. All SuperFlow dry gap eddy current absorbers can be interfaced with SuperFlow data acquisition and control systems for complete engine, dynamometer and throttle control. These systems integrate with personal computers running Supe
