Selection by Motor Frame Size
Motor Adapter Kits
Most motors use one of three mounting configurations for encoders:
- NEMA 56C 4.5" Face or Foot Mount
- 8.5" Modular FC Flange Face Mount (A.K.A. = 8.5" Accessory
Flange)
- Shaft Mount
Avtron manufactures encoders for all three of these
configurations. However, some older motors and large frame AC and DC motors may
not have standard encoder mounts.

In those cases, we offer adapter kits so one of the above
styles may be used to simplify the installation. Some large frame DC
motors may be supplied with 12.5" to 8.5" adapter flanges.
Avtron makes a 12.5" to 8.5" adapter flange B23688 to make it
easy to mount an M285. |

Some Reliance Electric motors have a 4.5" or 6.75"
flange. Avtron makes adapter flanges for these motors. The 4.5"
flange adapter is our B24049 and the 6.75" adapter is our B24221. Call us if you are not sure which to use. An
M3 Universal Encoder may
be better solution on these motors if Mill-Duty
specifications are acceptable. |

Contact us if you have special
installation requirements. Chances are we have already made an adapter kit
for your motor. We may also offer a shaft tach solution. |

Standard and Custom Stub Shaft Kits for Hollow Shaft-Mount Encoders
Avtron has many different styles of stub shaft kits for our M3 Universal Encoder, M585 Heavy, Mill-Duty (HMD)
SHAFTach (TM), and M685 Heavy, Severe-Duty
encoders. The M3 Universal Encoder can accept a shaft size of 5/8" to 2
3/8" (16mm - 60mm) to match the installation requirements of your
application. If you need a shaft to mount your encoder, we can select one from
our list of standard units, or design and build one to suit. Our shafts are
machined in house and sent out for plating to protect them from environmental
effects.

We typically design our shafts so they take advantage of the
outside diameter of the existing motor shaft where the machined surface is
true and yields the least runout. We do not have to worry about the end of
the shaft being flat and true to meet the installation requirements of the
encoder.
If you have a need for a stub shaft, let us know.
We can provide you with a part that is second to none!

Shaft Grounding Kits
Avtron manufactures shaft grounding brushes for most of our encoder products.
A shaft grounding brush is used to shunt motor shaft currents away from the
non-drive end motor bearing which is the smaller of the two motor bearings and
thus more susceptible to arcing damage when shaft currents seek ground through
the bearing. The shaft grounding brush is installed on the encoder and provides
a grounding lug for connection to earth ground. The brush itself rides on the
radial side of the motor shaft or an extension provided by Avtron for the
encoder being used. To select the shaft grounding brush information for the
encoder you are using go to the Sales Literature
Page or contact us for assistance.
