Several warning labels are affixed directly to the dynamometer. These warnings are discussed in
further detail below. Please take the time to read this page thoroughly before connecting and using
your dynamometer.
1. Make sure that all Magtrol dynamometers and electronic products are earth-grounded, to ensure
personal safety and proper operation.
2. Check line voltage before operation on any dynamometer that uses AC input power.
3. Make sure that dynamometers are equipped with a protective cover to prevent contact with the
rotating shaft and coupling. The protective cover must be equipped with a safety interlock to
disable the test motor if the cover is removed.
4. Make sure that all motors under test are equipped with appropriate safety guards.
5. Use caution with exposed brake surfaces. They have a tendency to become very hot during long
periods of operation.
CAUTION
BRAKE SURFACES MAY BECOME HOT
6. Do not lift the unit by the brake assembly, as it may cause damage to the torque sensor.
CAUTION
LIFTING BY BRAKE ASSEMBLY
MAY CAUSE DAMAGE TO
TORQUE SENSOR
7. When operating dynamometers with blowers, hearing protection must be worn.

Magtrol Hysteresis DynamometersChapter 1 – Introduction
GENERAL
INFORMATION
1.2 FEATURES OF THE HYSTERESIS DYNAMOMETER
All Magtrol Hysteresis Dynamometers (HD and ED Series) feature the following:
• Hysteresis Braking System: The dynamometers do not require speed to create torque, and
therefore can provide a full motor ramp from free-run to locked rotor along with precise
torque loading.
• Air Flow Sensor: Any Magtrol Hysteresis Dynamometer that is internally ported for
compressed air and/or blower cooling contains an air flow sensor that provides protection
against overheating and operator error
• Standard Torque Units: English, metric and SI are available.
• Easy Calibration
Unique features of each series are listed below.
1.2.1 HD SerieS
Magtrol’s HD Series Dynamometers are versatile and ideal for testing in low to medium power
ranges. Features include:
• Accuracy: ±0.25% to ±0.5% full scale, depending on size and system configuration.
• Custom Dynamometers: For special torque and speed requirements.
• Encoder Switch: Optional feature that allows the user to switch between a 60 and 600-bit
encoder or a 60 and 6000-bit encoder.
1.2.2 eD SerieS
Magtrol’s ED Series Dynamometers are high performance dynamometers specifically designed to
address the severe, high vibration conditions inherent in internal combustion engine testing. Features
include:
• Accuracy: ±0.25% full scale.
• High Speed Capabilities: 12,000 to 25,000 rpm, depending on model.
• Rugged Stainless Steel Shaft: Larger shaft for additional strength.
• Specially Reinforced Load Cell: Stainless steel pin used at contact point to prevent
premature wear from excess vibration.
• Gusseted Pillow Blocks: Adds additional front and rear support.
• Brake Cooling: Blower cooled to maximize heat dissipation.

Magtrol offers three types of dynamometer brakes to absorb load: Hysteresis, Eddy Current and Magnetic Powder. Each type
of Dynamometer has advantages and limitations and choosing the correct one will depend largely on the type of testing to be
performed. With over 50 models to choose from, Magtrol Sales professionals are readily available to assist in selecting the proper
Dynamometer to meet your testing needs.

*** 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.
