The Model 771 C-Face encoder is a rugged, high resolution, high temperature (100° C) encoder designed to mount directly on NEMA C-face motors. Both sides of the encoder are C-face mounts, allowing additional C-face devices to be mounted to this encoder. Other C-face units are kit type encoders, but the EPC Model 771 contains precision bearings and an internal flex mount thereby eliminating encoder failures and inaccuracies induced by motor shaft runout or axial endplay. This encoder is ideal for applications using induction motors and flux vector control.
The Model 771 provides speed and position information for drive feedback in a slim line profile. The thru-shaft design allows fast and simple mounting of the encoder directly to the accessory shaft or to the drive shaft of the motor, using the standard motor face (NEMA sizes 182TC - 256TC). The tough, all metal housing with thru-shaft design resists the vibration and hazards of an industrial environment.
