Mounting Styles
|
NEMA 56C Face or Flange |
Modular Bearingless |
|
(Solid Shaft
Coupled) Requires
NEMA 56C 4.5"
flange adapter (flowerpot) with
coupling.
Can often be replaced by
modular or
hollow shaft
encoders. |
 |
Also known as
NEMA 56C/NEMA FC
Face Mounted. Requires motor
stub shaft and one of the following: 115mm, 4.5", 6.75", 8.5", 12.5"
C/FC Face. Avtron's Admotec KA and
KX modular
encoders do not require a
C-Face to mount. |

Available models: AV485, M3-1,
M4-1, M485,
M925 |
Available models:
AV125, AV850,
KA,
KX, M56,
M67, M85, M115,

|
Foot Mounted |
Hollow Shaft/Tethered |
|
The
foot mounting method is usually used when
encoders are
coupled
directly to rolls, gear boxes, or motors without
C-Faces.
Can often be replaced by
hollow shaft encoders. |
 |
A
stub shaft is required. Shaft requirements depend on the
encoder selected.
An
Anti-Rotation Arm
is required.
Torque Arm
styles are used for larger motors. |
