Motor controller

IRZ develops its own line of electronic units and modules for electric motors’ control. This line includes controllers of three-phase motors. They are controlled by torque, speed and angular location.


  • smooth and precise regulation of operating mechanisms’ movement speed 
  • precise positioning of the machine tool and mechanism actuators 
  • integration into Automated process control systems
