Dynamometers can be used to determine virtual road loading of engines and full power train and are capable of testing for many different engine development activities, including:
Calibration of engine management controllers
Detailed investigations into combustion behavior
Power and torque measurements
Dynamometers: Functionality
Each dynamometer was created to measure the next characteristics:
Torque
Rotational speed
Power output of a combustion engine, electric motor or other power source.
An array of companies provide various solutions to measure these cat diagnostic tool, however the commonality is that all dynamometers function in the same fashion.
Dynamometers: Two Types
In addition to classification as absorption, motoring or universal, most dynamometers are classified in 1 of 2 categories:
1. Engine dynamometers were created for coupling directly to the driveshaft of a motor under test.
2. Chassis dynamometers measure the ability output of a drive train by using rollers turned by the tires of an automobile under test.
In addition to the 2 traditional dynamometer, select companies offer portable dynamometers that attach directly to the flywheel of an engine. This enables accurate measurement of engine output without removal of a motor from its drive train.
Dynamometer Designs
From simple power display systems with manual caterpillar service tools to completely automated testing solutions, there's a digital motor testing system to meet up your testing requirements.
Eddy current dynamometers: harness the magnetic flux between fixed and rotating electromagnets spun by the engine under test.
Powder dynamometers: create flux through the applying of a fine magnetic powder between the rotor and coil.
Electric Motor Testing Systems: Electric Motor Testing Systems are made to provide maximum reliability, excellent durability and performance; designed for testing electric motors from 5 to 4,250 hp.
Fan, hydraulic and water brakes: use air, water or hydraulic fluid to offer a sign of the ability applied to the system
