Product Details

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 control unit. The braking torque can be finely adjusted on the 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 accessory sets:
PT 500.13 Couplings
PT 500.14 Belt drive
PT 500.15 Damages to gears
PT 500.19 Electromechanical vibrations
