Product Description

Originally designed to test window lift gear motors, Magtrol’s FMF Series Fixed Motor Fixtures are used to secure motors in place while running any test. These versatile fixtures align the motor under test with Magtrol’s HD-100, HD-106, HD-400, HD-500, HD-700 and HD-800 Series Dynamometers for easy setup and coupling—couplings can be provided upon request. Various adaptor rings (sold separately) can be customized to allow several different motors to be tested on the same fixture.

FMF Fixed Motor Fixtures can be mounted to any Magtrol Dynamometer T-slotted long base plate or any Hysteresis Dynamometer Table with grooved table top (TAB 1457S, TAB 0800L and TAB 0825L). These fixtures are equipped with a precisely located rectangular key on the bottom of the plate for easy centering. Also included are four adjustable clamping levers and T-nuts.

Features

  • For use with Magtrol HD-100, HD-106, HD-400, HD-500, HD-700 and HD-800 Series Dynamometers with long T-slotted base plates
  • Accommodate face mount motors of various sizes (depending on model)
  • Provides rigid mounting for face mount motors under test
  • Base plate contains a rectangular key for proper alignment
  • Secure anchoring system
  • Direct mounting to Magtrol TAB Series Dynamometer Table or dynamometer base plate (depending on model)
  • Adaptor rings (sold separately) allow different styles of motors to be tested on the same fixture (adaptors manufactured per customer requirements)

                    [post_content] => Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty).  With a 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.  Brake cooling is provided by convection (no external source), by compressed air or by dedicated blower, depending on the model.  All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% full scale — depending on size and system configuration.
To better integrate dynamometers into systems, Magtrol offers both long and short base plates.  The shorter base plate facilitates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.

The Hysteresis Braking System

All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.

Coupling Guards help keep objects from vertical interference and aid in preventing accidental coupling contact during rotation. The guard length required will change according to the coupling size used with the dynamometer.

Magtrol Coupling Guards are not explosion proof and are not intended as protection against catastrophic coupling failure.

            [post_content] => Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty).  With a 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.  Brake cooling is provided by convection (no external source), by compressed air or by dedicated blower, depending on the model.  All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% full scale — depending on size and system configuration.
To better integrate dynamometers into systems, Magtrol offers both long and short base plates.  The shorter base plate facilitates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.

The Hysteresis Braking System

All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.
