  Inductor Dynamometers  

(click on images for large view)

  
  In simplified terms, an inductor dynamometer consists essentially of a rotor, stator and toroidal field coil.  With the rotor driven by the test device, eddy currents are induced in the rotor opposing an equal electro-magnetic force generated in the restrained stator.  This opposition causes a loading effect.  Capable of precise control of this load, the inductor (eddy current) dynamometer is by far the most widely used method today for power absorption.   wpe3B.gif (29094 bytes) wpe40.jpg (169825 bytes)  
           
 

DC Dynamometers

        
 

The DC dynamometer system is an adjustable voltage system using the DC dynamometer as a conventional DC shunt motor.   When in the absorbing mode, power is returned to the AC line by inverter action.  For motoring, power is taken from the three phase line, converted to DC and applied to the dynamometer armature circuit.  Speed regulation is controlled by field weakening, where an increase in field current will reduce the dynamometer speed and a reduction in field current will increase the speed.   

  Dyno One has provided repair and remanufacture of motoring dynamometers for nearly 20 years.  Our experience has allowed us to modify existing design to enhance performance from the OEM.  From basic rebuild and clean-up to complete remanufacture and rewind, Dyno One is your source for DC dynamometers.

  • Variable drive including, ACU:  Auxiliary supplies, torque conditioning, command relay and low voltage protection.  ICU:  Main supply, general circuit breaker and protection switch.  FIU:  Filtering module.  ISU:  Motor/generator converter module with IGBT semi-conductors supplying the direct bus
  • Each phase of the asynchronous motor is controlled by IGBT's computing between a positive and negative voltage continuously with the DTC
  • Remote control RS485 serial link with Profibus Master DP communication protocol
  • Electrical control cabinet is provided by ABB

  We can also provide complete integration, installation and startup of the D2T Asynchronous Dynamometer System.        
           
 
New Parts
       
  Dyno One now stocks new parts for many types of inductor dynamometers with many within OEM specifications.  We stock a complete line of Bearing Caps (Vent Rings), Water Baffles, Trunnions, Eddy Current Rings, Shafts, Rotors and Rotators for a variety of dynamometers with shipping within 72 hours for most parts.  Having parts available also allows us to expedite repair and remanufacture of your inductor dynamometer.   wpe52.jpg (28556 bytes)    
           
 
Automated Lift Systems
        
  Dyno One can design and manufacture new automated lift tables or modify an existing table to your specific needs.  Please contact us for more information on automated tables designed to your requirements.    wpe29.jpg (55417 bytes)    
           
 
Dynamometer Bases/Starters
        
  We have provided many types and sizes of bases for dynamometer applications.  Our bases are designed and structured to minimize resonance frequencies that excite vibrations into the test system.  These vibrations over time can cause premature bearing and mechanical related failures.  In addition, we supply and engineer starter systems for all types of gas and diesel engines including DC, AC and Air type starters including repair of such.   wpe1F.jpg (53466 bytes)    
           
 
Inertia Stands/Systems
        
  Need to add a little "punch" to your testing needs.  Dyno One designs and builds inertia wheels and complete stands including interconnecting devices.   wpeE.jpg (22960 bytes) wpe15.jpg (27865 bytes)
