FAQ

How do I adjust the speed on this hollow shaft variator?

The speed is adjusted mechanically via the integrated control dial on the variator section. This changes the internal contact diameters of the discs, allowing for a smooth transition of output speeds while the motor maintains a constant RPM.

What are the maintenance requirements for the hollow shaft?

The hollow shaft should be coated with an anti-seize compound during installation to prevent fretting corrosion between the motor and the machine shaft. Periodic inspection of the internal keyway is recommended to ensure secure torque transmission.

Can this unit be controlled by an external PLC?

While the speed adjustment on this specific model is mechanical, the motor itself can be started, stopped, or monitored by a PLC via a standard motor starter or a Variable Frequency Drive (VFD) if electrical speed trimming is also required.
