Rosenberry Hub

Starting protection for synchronous machines



Rosenberry Hub

The Rosenberry Hub - a modern, state of the art hub offering trouble-free starting.

Fixed speed synchronous motors that are required to start asynchronously require extra switching devices on the rotor to allow the induced field currents to flow safely without damaging any of the components.

Our experts have designed the Rosenberry Starter Hub which can be installed on new equipment or retrofitted to existing machines, with bespoke variants of the hub, dependent upon the design of your motor:

- Rosenberry Hub for Shaft End Mounting

- Split Rosenberry Hub for Mid-Shaft Mounting where there is insufficient space for conventional solutions

Over 30 years of experience have ensured improvements have continually been made, developing upon the Optimum Angle and Rotosyn starting hubs. We now offer a designed solution offering increased reliability and ATEX/IECEx Zone 2 certification.

The Rosenberry Hub is marketed under our Quartzteq brand and more detailed information can be found on the Quartzteq website.
