unbalance drive unit

US Patent for Measuring unit and measuring assembly for

Since drive means 70 and also no further part, despite measuring unit 20 as described, is connected to the machine frame, a self-contained measurement of unbalance forces can be achieved. A rotational encoder unit 100 provides the rotational position of main shaft 12, such that forces measured by measuring unit 20 can be corresponded to a
