PROBLEM

Our customer shreds scrap wood and bark into mulch. His shredder includes a flywheel which helps the mill keep going under heavy loads. Unfortunately, this increased inertia really loads up his DC motor during start up.

SOLUTION

This application was ideally suited for a centrifugal clutch. The no-load start feature is ideal for letting the motor get up to speed before picking up the shredder.

The centrifugal clutch can also provide overload protection when sized properly. This was the next real challenge, identifying the best size for this installation.

After reviewing horsepower, speed, starting frequency and system inertia, we were able to give this customer a couple of options.

If you have a shredder or any other high inertia system which is difficult to start—give us a call.
