Applications

In the laboratory, the DSP7010’s high sample rate provides superior resolution for data acquisition and curve plotting. This allows capturing more usable motor test data during switching, breakdown and other transitional areas of the motor test curve. For production and incoming inspection, the DSP7010 displays torque, speed and power at all times, allowing the Controller to be used as a manual stand-alone unit or as part of a complete PC system.

                    [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.

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.

            [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.

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.
