Streszczenie / Summary:

The article describes investigation of dynamic properties of the proportional valve with synchronous
motor type PMSM. Authors proposed proportional valve, whose slider was controlled by
a synchronous motor type PMSM. Proposed valve has been tested using flow meter and hydraulic
supplier work with different pressure. Investigated the flow characteristics, the step response and
torques acting on the motor shaft. In order to carry out research dedicated test stand was built. The
master controller was based on modern PLC with touch screen panel. As a slave drive was used
servo-inverter. For easier communication the operator with the control system, designed dedicated
visualization witch allowing the setting of basic drive parameters. The collected informations can
be used to estimate the position of the actuator or supervise his work.
