Help with Electrical Motor as Dynomometer!

[EpicSolutions]

I am looking to use an electrical motor as a loading device for an Engine Dynomometer, and I need some help from all the people with more experience in electric motors.

I need an electrical motor that can withstand the following conditions;

- Capable of absorbing 80kw / 100hp
- Capable of spinning at around 2000rpm


Please help me, I cant seem to find any information about the kind of motor I could use.

An example/ link to a product would make me very happy. I can find 80kw motors, but I think that a motor can absorb more than it is rated as an output.

This used to be DC motor territory. Regeneration via a thyristor bridge was the rule.

Rough measurements could be made directly on armature voltage and current and torque and absorbed power calculated with a few percents accuracy. For better accuracy, a torque transducer was used.

Today, a standard induction motor and a VFD with regeneration can be used and the available measurement possibilities are generally much better than before.

Half full - Half empty? I don't mind. It's what in it that counts.

A 100hp, 1800rpm squirrel cage motor with a VFD would work. You can either use a 80kW resistor and waste a bunch of heat or regenerate onto the power line. The motor should be OK providing a load up to 2000rpm. however, if you think you'll be going even higher in frequency then you need another plan.
