If the traction sheave cannot be removed…what is the solution?

As the sheave is situated within the drum of the drive alongside the permanent magnets it cannot be replaced. To prevent the need of this ever occurring, the sheave is made of stronger that normal steel (HB260-300) meaning that the sheave will last a lot longer. Also, the manufacturer has also increased the amount of grooves so that if this were ever to wear, the ropes could be moved into different grooves which consequently doubles the usable life of the drive.

What is the best option for the motor-variable frequency drive?

At GLE we supply all of our gearless drives with Vacon variable frequency drives.

We recommend the use of these drives with the Diana gearless traction range as we believe to have found the perfect combination. It should also be known that our gearless machines will work with any other type of variable frequency drive. Our technical support team is available if you require more information regarding the pairing of a Diana motor with another type of variable frequency drive.
