Measurement of pneumatic system parameters.
Analysis of servo-pneumatic system parameters.


Laboratory Brake Loading System

The laboratory brake loading system is used to load test hydraulic motors. The electromagnetic brake Telma AD 50-90 is used to achieve variable loading torque. The hydraulic motor and electromagnetic brake are connected by a rigid coupling, and the test bench is adjustable, allowing different types of hydraulic motor to be tested. The hydraulic power unit Hansa-Flex with several directional control valves operated by a PLC unit is used to drive the hydraulic motor. The laboratory system also consists of measuring equipment for motor load torque, rotational speed and hydraulic motor oil pressure drop.

Technical specifications:
Max. load moment: 900 Nm @ 1000 min-1
Max. brake rotational speed: 4500 min-1
Max. pump flow rate: 15 l/min
Max. oil pressure: 210 bar
