Installing Avtron Encoders for Brake Motors

Avtron Encoders may be installed on brake motors with little difficulty. The
first option is to use an M285
SMARTachTM with its 8.5" FC flange mount
and install it to the motor as shown in the picture. Since this unit has an
8.5" FC flange on its outboard side, the brake can be mounted to the tach
with its installation bolts going through the M285 and into the motor frame.
Deflection of the motor shaft will occur when the brake is applied. With the
M285 rotor attached to the motor shaft near the motor bearing, minimal
deflection is seen by the rotor so there is no danger of exceeding the air gap
between the rotor and sensor within the M285.
The second solution is to use a through shaft brake and mount an M3 Universal Encoder to the end
of the shaft outboard of the brake. Since the encoder floats with the shaft, any
deflection during braking will not affect encoder performance. Since the
M3 Universal Encoder mounts to the shaft, a stamped steel brake may be used
since there is no need for a machined surface on the brake for an encoder.
Avtron saves you money on the brake as well!

If you are working with motors that use band brakes, Avtron shaft tachs may
be used to simplify the installation and alleviate alignment issues and
expensive foot mount brackets. We can provide a custom stub shaft that mounts to
the end of the motor shaft within the brake drum. The shaft would be made long
enough to allow room for the encoder to mount with an anti-rotation bracket to
hold it steady. An example of this is shown in the picture where an M685
SHAFTachTM is mounted minus the anti-rotation
bracket which is installed when the motor is mounted on its base.
