ENGINE DYNAMOMETERS MAGTROL offers 3 types of dynamometer brakes to absorb load: Hysteresis (HD Series), Eddy-Current (WB Series) and Magnetic Powder (PB Series). Each type of Dynamometer has advantages and limitations and choosing the correct one will depend largely on the type of testing to be performed. With over 50 standard models to choose from, Magtrol Sales professionals are readily available to assist in selecting the proper Dynamometer to meet your testing needs. FEATURES ▪ Maximum Torque: 55 ... 250 lb·in (6.5 N·m ... 28 N·m) ▪ Hysteresis Braking System ▪ Motor Testing: from no load to locked rotor ▪ Standard Torque Units : SI (English & Metric available upon request) ▪ Accuracy: ± 0.25 % (full scale) ▪ Blower Cooled: to maximize heat dissipation ▪ Air Flow Sensor: for protection against overheating and operator error ▪ Specially Reinforced Load Cell: stainless steel pin at contact point prevents premature wear from excess vibration ▪ Larger Shaft: for additional strength ▪ Gusseted Pillow Blocks: for additional front and rear support With Magtrol’s Engine Dynamometers, high performance motor testing is available to manufacturers and users of small engines. Magtrol’s Engine Dynamometers have been designed to address the severe, high vibration conditions inherent in internal combustion engine testing. The Engine Dynamometers are ideally suited for emissions testing as set forth in CARB and EPA Clean Air Regulations. The Dynamometers will offer superior performance on the production line, at incoming inspection or in the R&D lab. Magtrol’s Engine Dynamometers are highly accurate (± 0.25 % of full scale) and can be controlled either manually or via a PC based Controller. For a small engine test stand, Magtrol offers a full line of controllers, readouts and software. As with all Magtrol Hysteresis Dynamometers, engine loading is provided by Magtrol’s Hysteresis Brake, which provides: torque independent of speed, including full load at 0 rpm; excellent repeatability; frictionless torque with no wearing parts (other than bearings); and long operating life with low maintenance. © 2020 MAGTROL | Due to continual product development, Magtrol reserves the right to modify specific

ED SERIES DYNAMOMETER SELECTION Magtrol’s Hysteresis Dynamometers cover a wide range of Torque, Speed and Mechanical Power ratings. To select the appropriate size Dynamometer for your motor testing needs, you will need to determine the Maximum Torque, Speed and Power applied to the Dynamometer. MAXIMUM TORQUE The Magtrol Hysteresis Absorption Dynamometer will develop braking torque at any speed point, including low speed and stall conditions ("0" rpm). It is important to consider all torque points that are to be tested, not only rated torque, but also locked rotor and breakdown torque....

ED SERIES SYSTEM CONFIGURATIONS OPEN LOOP SYSTEMS Magtrol offers both open loop manual test systems and PCbased closed loop test systems. A typical open loop system will consist of a Dynamometer and a Magtrol DSP 7000 Dynamometer Controller. A Magtrol Single or Three-Phase Power Analyzer, which allows for the capturing of volts, amps, watts and power factor, can be included as an option. An open loop system is often used for quick pass / fail testing on the production line or at incoming inspection. Magtrol’s DSP 7000 Dynamometer Controller provides pass / fail testing as a standard...

However, operating for extended periods at high temperatures will result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where continuous duty is desired for...
