FAULHABER AEMT-12/16 L absolute encoder

Click2Contact

The magnetic AEMT-12/16 L absolute encoder from FAULHABER delivers absolute angle information with a preset multiturn resolution of 16 bits (65536 revolutions) and a single-turn resolution of 12 bits (4096 steps) for commutation, speed control and motion control.

The encoder can be combined with brushless DC motors of the B, BX4 and BP4 series. The encoder is connected via ribbon cable; suitable connectors and different filter modules and adapters for connecting to FAULHABER speed and motion controllers are available. Advantages include a cable length of up to 5 m; efficient operation with low torque ripple; and no reference run is necessary after switch-on.

Position data is queried by an SSI interface with BiSS-C protocol. With a line driver, the interface is designed differentially and based on the RS422 standard. Therefore, it’s possible to position the motor/encoder unit up to 5 m away from the controller.

The BiSS-C protocol is designed for applications in which high transmission speed, flexibility and simple implementation are required. For FAULHABER, Digital Hall sensors for commutation of the motors are no longer generally needed. With AEMT, sine commutation is possible, as is efficient operation of the motor with minimal torque ripple.

The encoder can be connected to a main supply and a backup supply (eg, a battery) so that the count is retained and a new reference run is not necessary. The multiturn count can be reset via an additional interface pin during start-up.
