Product Description
With a Magtrol Engine Dynamometer, high performance motor testing is available to manufacturers and users of small gas engines. Magtrol’s Engine Dynamometers have been designed to address the severe, high vibration conditions inherent in internal combustion engine testing.
Engine Dynamometers are part of Magtrol’s line of Hysteresis Dynamometers so they are highly accurate (± 0.25% of full scale) and can be controlled either manually or via a PC-based Dynamometer Controller. For a small engine test stand, Magtrol offers a full line of controllers, readouts and data acquisition software.
An ED Series Engine Dynamometer is ideally suited for emissions testing as set forth in CARB and EPA Clean Air Regulations. The dynamometers will offer superior performance on the production line, at incoming inspection or in the R&D lab.
As with all Magtrol Hysteresis Dynamometers, engine loading is provided by Magtrol’s Hysteresis Brake which provides: torque independent of speed, including full load at 0 rpm, excellent repeatability; frictionless torque with no wearing parts (other than bearings); and long operating life with low maintenance. Magtrol provides a NIST traceable certificate of calibration, and calibration beam with each engine dynamometer.

*NOTE: Operating at the continuous power rating for periods of up to 4 hours is acceptable. However, operating for extended periods at high temperatures will result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where continuous duty is desired for longer time intervals, component temperatures should be maintained less than 100°C; monitoring the outside brake surface temperature is a sufficient reference. ** The maximum speed will depend on what type of keyway (if any) is used on the shaft. Unless specified, the dynamometer shaft will be made without a keyway.

Dynamometer Selection
Magtrol Dynamometers cover a wide range of Torque, Speed and Mechanical Power ratings. To select the appropriate size Dynamometer for your motor testing needs, you will need to determine the Maximum Torque, Speed and Power applied to the Dynamometer:
Maximum Torque
It is important to consider all torque points that are to be tested, not only rated torque, but also Locked Rotor and Breakdown Torque. Dynamometer selection should initially be based on the maximum torque requirement, subject to determining the maximum power requirements.
Maximum Speed
This rating is to be considered independent of torque and power requirements, and is the maximum speed at which the Dynamometer can be safely run under free run or lightly loaded conditions. It is not to be considered as the maximum speed at which full braking torque can be applied.
Maximum Power Ratings
These ratings represent the maximum capability of the Dynamometer Braking System to absorb and dissipate heat generated when applying a braking load to the motor under test. The power absorbed and the heat generated by the Dynamometer is a function of the Torque (T) applied to the motor under test, and the resulting speed (n) of the motor. This is expressed in these power (P) formulas:
SI: | P (watts) | = | T (N·m) | x | n (rpm) | x | (1.047 × 10-1) |
English: | P (watts) | = | T (lb·in) | x | n (rpm) | x | (1.183 × 10-2) |
Metric: | P (watts) | = | T (kg·cm) | x | n (rpm) | x | (1.027 × 10-2) |
All of Magtrol's controllers, readouts and software calculate horsepower as defined by 1 hp = 550 lb·ft / s. Using this definition: |
| hp | = | P (watts) | / | 745.7 |
To calculate power, use Magtrol's online motor power calculator |
The Dynamometer’s ability to dissipate heat is a function of how long a load will be applied. For this reason, the Maximum Power ratings given are based on continuous operation under load, as well as a maximum of 5 minutes under load.
To safely dissipate heat and avoid Dynamometer failure, the maximum power rating
is the most important consideration in selecting a Dynamometer.
