It consists of a rotor and a stator. Contact our Engineering team today to discuss your project requirements. Jun-16 AG400 DYNAMOMETER Page 1 of 7 Specification AG400 Eddy Current Dynamometer 1. Type # 1. Dynamometer Controllers. The unit is supplied in a 19 inch rack mounting module and comes complete with interconnecting cables between the controller, power module and ECB Series Electric Motor Dynamometers allow for ease of testing as they offer the advantage of dissipating heat via air-cooled fin technology. When any conducting wire is brought near alternating current, eddy currents are produced. Therefore, it is also known as fluid friction dynamometer. A Linear Induction Motor (LIM) operates on the same principles as a rotary induction motor but produces linear motion rather than rotational motion. Construction of Hydraulic Dynamometer See full list on elprocus. here Eddy Current Dynamometer : It consists of a stator on which are fitted a number of electromagnets and a rotor disc made of copper or steel and coupled to the output shaft of the engine. C operation: The dynamometer instrument is used to measure alternating current or voltage, the moving coil–due to its inertia takes up a position where the average deflecting torque over a complete cycle is balanced by the restoring torque of the spiral spring. Designed for use with any Magtrol Hysteresis, Eddy-Current or Powder Dynamometer, Magtrol In-Line Torque Transducer or auxiliary instrumentation, the DSP 7010 can provide complete PC control via the USB or GPIB interface. Lec : 1. SE Series - Eddy Current Dynamometers Technical Data Introduction The dry gap computer compatible SE series Dynamometers offer a wide range of Eddy current Machines having capacities from 5 kW to 720 kW for engine testing. It has constant braking torque and has no shock characteristics. 00625240379 Registro Imprese (BO) 00625240379 The air cooled eddy current dynamometer delivers an exceptional response time compared to alternative types of dynamometers. Through The customer can chose whether to mount the dynamometer or the motor on the lift table. r. State of art of components, design and engineering combine to redefine eddy current dynamometer performance and sets new standards in maintenance free, ruggedness and flexibility. A Eddy Current Dynamometers (Dynos) Providing Precise Control and Low Maintenance. These absorbers work by generating heat through electromagnetic induction as the rotor moves within the magnetic field. Eddy Current Chassis Dynamometers. It can measure power upto 300 HP with maximum speed 6000 rpm. Why? Apr 17, 2014 · The Towing Dyno uses an eddy current absorber linked to an axle system to absorb energy, which is measured by a load cell in the drawbar of the trailer. It is one of a range of dynamometers that have been designed specifically for testing engines and their Eddy Current Dynamometers facilitating testing of Diesel, Gasolene,CNG engines widely used in Automotive, Marine, Industrial & Combat Engines ISO 9001 COMPANY +91 20-2687-0882 sales@sajdyno. Eddy current dynamometers offer excellent control response to electronic Sep 28, 2020 · Pick the best style dynamometer for your application! Each type of configuration has its own strengths and weaknesses. Max Torque : 37 KgM (370 Nm) The document discusses hysteresis motors, which operate based on hysteresis and eddy current losses induced in the rotor by the rotating magnetic field of the stator windings. Eddy Current Dynamometer: For an eddy current dynamometer, the power (P) is calculated using the same formula as for the absorption dynamometer: P = 2πNT Where: P is the power output (in watts), N is the rotational speed of the system being tested (in RPM), and May 19, 2016 · Final product for the senior design class at San Diego State University.
