Rotork A type
Thanks to our golden sponsor, Volvarber Kft. and Attila Honti, the Rotork A drive deserves a special chapter in the history of the ExMuseum. On this page you will find some short descriptions, spectacular pictures and some interesting documents about this historical instrument.
The Rotork A series was the factory’s first truly successful electric compact drive. The “set” version worked without built-in controls, the pak version (on the picture) with built-in controls.
Its control enabled conventional relay control with end position feedback with built-in mechanical torque sensing. Its local display was suitable for indicating end position status and intermediate status.
Ex elements reflect the technical solutions of the age: 3 angle head screws, Ex auxiliary locking ring of electronics cover. Its transmission structure continues to live on in several new products: IQ series, K series, AWT series
