Mycronic Belt pulley Fi-motor D-012-0718-3
This is a Fi-motor belt pulley used in MyData/Mycronic MY-series pick-and-place machines, providing the precision drive pulley component for the Fi-axis (phi/rotation axis) motor belt drive system within the placement head assembly.
Key characteristics:
- Application: MyData/Mycronic MY-series pick-and-place machines equipped with Fi-axis belt drive placement head
- Function: Serves as the drive pulley for the Fi-axis motor belt transmission, transferring rotational motion from the Fi-axis servo motor to the belt drive mechanism that controls nozzle rotation or placement head rotational positioning; precise pulley geometry is critical for accurate belt tension, drive ratio, and positional accuracy of the Fi-axis
- Manufacturer: MyData/Mycronic (D-prefix indicates a device or tooling-level part number)
- Part number: D-012-0718-3 ("-3" denotes a specific variant or revision)
- Type: Belt drive pulley / Fi-axis motor drive component
- Category: Machine mechanical / drive system component
- Wear Item: Belt pulleys are subject to wear, belt groove degradation, and dimensional changes over time; regular inspection recommended as part of preventive maintenance
Signs of Pulley Degradation:
- Fi-axis positioning errors or rotation inaccuracy
- Belt slippage or irregular drive transmission
- Abnormal noise from Fi-axis belt drive during operation
- Visible pulley groove wear or belt tracking issues
