Next Generation Power Amplifier Unit

A New Generation PAU

DS820 Eddy-Current Power Amplifier Unit

Integrate this newly designed PAU into your existing test cell, or include it in your new installation. It interfaces with PCs and PLCs running 3rd party software, or with any Dyne Systems dynamometer controller. It is also capable of stand-alone operation. Applications can be everything from manual to fully integrated, closed-loop implementation.

Midwest Dynamometer Stretches the Envelope

Turbine Engine Test System: 4,000 HP at 30,000 RPM!

4000 horsepower, 30,000 rpmMidwest Model 932 Wet Gap Eddy Current Dynamometer tests engines at up to 30,000 rpm

The Midwest model MW932 is a wet-gap eddy current dynamometer with a maximum absorbing power capacity of 4,000 hp, from 1,500 rpm to 3,000 rpm. It is trunnion mounted in pedestals on a base.

Utilizes a Speed Increaser

A 10:1 speed increaser is utilized to reconcile the difference between the dynamometer speed and the device under test (DUT), providing operation at peak efficiency.

AC Motor Negates Inertia, Provides Zero Load

An AC motor is used to negate the inertia of the eddy current and the speed increaser, to provide a zero load at the output shaft of the speed increaser. The AC motor also assists in maintaining this zero load during acceleration.

Nominal Capacity:4,000 hp
Maximum Input Speed:3,000 rpm
Standard Output Speed:Up to 30,000 rpm
Ratio Range:10:1
Accel/Decel Rate:2,000 rpm/sec (Standard)
