NEMA C Face Mounting

NEMA 56C and 5 PY Mounted Encoders

Avtron offers many different encoder styles to fit nearly every installation requirement. Many older installations used the NEMA 56C face or foot mounted tachogenerator like the GE BC-42 and BC-46 or Reliance RE-210. Upgrading these installations is easy with Avtron foot or face mount encoders. Use Thomas CCX Couplings (below) for best performance.

• M385
• M485
• M945

Many Reliance Electric Installations used resolvers on 2.5" 5PY flanges.

For 5PY Mounted Encoders:

• M925

Any of the above installations may be retrofitted with shaft tachs by removing the adapter flanges and couplings from the motors and mounting an M3 Universal Encoder or M585/M685 SHAFTach (TM) to the existing motor or stub shaft.

Guide to Proper Designation of Hubs

Style CC

This coupling has both hubs inverted and is designed to fit shafts normally encountered at a given torque range. Ideal for use where space limitations require close coupling of the shafts. 

Torque capacities are based on smooth drives with moderate torque fluctuations. Reduce ratings to 1/3 the value shown for severe applications such as indexing drives where torque reversals occur.

All Thomas disc couplings meet NEMA frame sleeve bearing motor specifications without modification or the addition of end-float restricting devices.
