I need to retrofit some encoders onto some old motors that presently have analog tachogenerators mounted on them. What should I use?
• If your analog tachogenerators are BC46, BC42, or RE210 flange styles mounted on NEMA 56C face adapters, then often all you need to do is mount any solid shaft Avtron encoder with a NEMA 56C face. This method allows you to retain the same coupling and mounting bolts. It is a direct mechanical replacement. Our AV485 is a typical example. • For an even more durable installation, consider removing the flange adapters and couplings and installing a modular encoder with no bearings, couplings, or other moving, wearing parts. Examples include: AV125, AV850, M56, and M85. • If foot mounted: all of the Avtron Heavy Mill and Severe Duty (HMD/SD) encoders (such as AV485) have the same shaft size and shaft centers as BC46/BC42 tachogenerators. The mounting base dimensions are identical so no modification to the mounting holes is required. These foot mounting kits are available to match the footprint of either Avtron Classic encoders or analog tachogenerators. Simply specify the foot mount kit y
