Mounting Bracket and Protective Cover
The Uni-Bracket allows for the tethering of the encoder (Models 260 & 702) to any 4.5" C-Face (5.875" BC mounting holes) and can be employed with or without the Uni-Cover. The non-conductive bushing provides an electrical isolation barrier, negating the potential for Electro Static Discharge and resultant encoder bearing damage. The bushing can also be slid in or out of the forked bracket to allow for mounting to comparably sized IEC C-faced or other non-NEMA dimensioned motors. Even though all EPC encoders are designed and built to robust specifications, and utilize all-metal parts, a protective cover is often considered a cheap insurance policy against physical abuse. The all-metal Uni-Cover provides this protection. Designed to allow for the fitting of most EPC thru or hollow bore encoders, the Uni-Cover matches up with the 5.875" bolt pattern found on the NEMA 4.5" AK C-face mounts. It is slotted to accommodate either the Uni-Bracket or the non-conductive flex of the Models 775 and 776, along with either cable gland or body mounted connector encoder styles.
Adaptable encoders include;
Model 260 Thru-Bore Requires Uni-Bracket for motor mounting.
The most economical solution where the motor shaft is 0.625" (05 15mm) or less.
For demanding performance Vector applications where high speed and frequency response is required (up to 8000rpm & 300Khz respectively).
Model 702 Blind Hollow Bore Requires Uni-Bracket for motor mounting.
Where a body-mounted connector is desired and motor shaft diameters do not exceed 0.625" (or 15mm).
Model 775 Does NOT require Uni-Bracket.
775 "Style A" flex option allows for direct motor mounting where shaft diameters exceed 0.625" (up to 1.375" or 35mm).
Model 776 Does NOT require Uni-Bracket.
776 "Style A" flex option allows for direct motor mounting where shaft diameters exceed 1.375" (up to 1.875" or 48mm).
Today, many motor manufacturers provide a "Standard Mechanical Interface" on their Vector and Inverter Duty products, such as a 4.5" or 8.5" C-face, but not always. On occasion, the scope of your project requires that you attempt to retrofit an encoder to an older motor so as to interface with the new drive you have selected. Whatever the case, with EPC's complete family of "easy, anyone can mount" motor to encoder offerings, a technically and commercially viable solution can usually be selected and applied. Please also see EPC's Models 770 & 771 C-face encoders for additional motor-to-encoder solution alternatives.
