ED Series Dynamometers

ED Series Dynamometers

Mustang’s ED Series Air-Cooled Engine Dynamometers are the answer for most engine testing applications due to their excellent stability, accuracy and testing range. Unlike similarly priced water brake systems, the ED Series offers reliable, steady state control from near zero speed to maximum RPM.


Standard Features


  • Fast Response Time
  • Accurate Load & Inertia Simulation
  • Maintenance Free – No Water
  • Four Ranges to meet most applications
  • 40 Range – High speed small displacement engines
  • 70 Range – 4 or 6-cylinder automotive engines
  • 140 Range – 6 or 8-cylinder automotive applications and light-duty diesel engines
  • 400 Range – Large heavy-duty diesel engines.

    Overview


    ED Series Engine Dynamometers

    Mustang’s ED Series Engine Dynamometers are available in four ranges – the 40 Range for high speed small displacement engine testing (internal combustion engines), the 70 Range for standard automotive engines and high speed four and six cylinder racing engines, the 140 Range for standard 6-cylinder and 8-cylinder automotive applications and light and medium duty diesel engines, and the 400 Range for testing large diesel engines.  The 70 and 140 Ranges each have three separate products to handle a wide range of power requirements.  The 40 Range is available with two products and the 400 Range is available with three.  Additionally, each system is available with optional mechanical equipment upgrades to augment the testing needs for each client – including electric starter systems, electric motors for measuring engine parasitic losses, and gear reducers for testing very high RPM engines common in motorcycles, ATVs, and snowmobiles.

    Fast, Accurate, and Maintenance Free

    The air-cooled eddy current dynamometer delivers an exceptional response time compared to alternative types of dynamometers.  For instance, the ED40-10 has a response time of approximately 150 ms.  Compared to an equally sized AC Dynamometer with a 100 ms response time at over twice the price, the ED40-10 is an excellent choice.  Compared to the water cooled Eddy Current with < 500 ms response time and the water brake with < 1 second response time, the Air Cooled Eddy Current is by far the best choice.

    The Electromagnetic Absorption Module

    The ED Series Engine Dynamometers utilize Electromagnetic Absorption Modules (i.e. Eddy Current Brakes) to apply a load to the engine under test.  The Eddy Current Brake is ideal for engine testing due to its frictionless operation and relatively easy to maintain design.  Each absorber is equipped with a series of coils, which, when energized with power from the system controller, will create a magnetic attraction between the stator assembly and the rotor assemblies which are connected to the test system shaft.  This creates a braking, or loading action against the engine.  A load cell measures the reaction torque while a highly accurate hall-effect speed sensor measures shaft speed.

    Another excellent attribute of the Eddy Current Brake is the absence of water as a cooling medium.  The Eddy Current Brake is air-cooled and uses specially design rotor fins to aid in the cooling process as the brake rotors spins at high speeds.  Each system is also available with optional cooling fans to keep the system at a lower temperature during long term testing procedures, such as with durability testing.
