PT 500.05 Brake & load unit



  • Generation of a loading torque
  • Two speed and torque ranges
  • Vented magnetic particle brake with display and control unit


Technical Description

Many vibration phenomena can only be achieved when the system is under load. The brake and load unit is used to generate vibration as a function of torque, e.g. in toothed gearing mechanisms or electric motors.

It consists of a magnetic particle brake and an electric display and control unit. The braking torque can be finely adjusted on the display and control unit. The exciter current is applied as a measure of the braking torque and is indicated digitally on a display.

An integrated belt drive, with a free shaft, provides the brake with two torque and speed ranges. The energy is converted by the brake into heat and discharged to the ambient air by a fan.

The brake can be quickly and precisely mounted on the slotted plate of the PT 500 base unit.
PT 500.05 is used with the following kits:
PT 500.13 Couplings
PT 500.14 Belt drive
PT 500.15 Damage to gears
PT 500.19 Electromechanical vibrations
