INCREMENTAL ENCODERS

 
Incremental encoders are sensors capable of generating signals
in response to rotary movement. In conjunction with mechanical
conversion devices, such as rack-and-pinions, measuring wheels or
spindles, incremental shaft encoders can also be used to measure
linear movement. The shaft encoder generates a signal for each
incremental change in position.

With the optical transformation, a line-coded disc made of metal,
plastic or glass and positioned on a rotary bearing interrupts the
infra red light ray emitted by gallium arsenid sender diode. The
number of lines determines the resolution, i.e. the measuring points
within a revolution. The interruptions of the light ray are sensed by the receptor element and electronically processed. The information is
then made available as a rectangular signal at the encoder output.

ABSOLUTE ENCODERS

 
Absolute shaft encoders, also known as shaft-angle encoders, are by no means used only to detect angular positions. They are also suitable for linear movements that can be converted into rotary movements by a toothed belt, drive pinion, or wire winch.

The special feature of absolute shaft encoders is that they assign
a unique, digitally encoded signal to each individual measured
increment. The method of transducing prevents erroneous readings,
whether by a power failure, or by a transient malfunction. After the
encoder is switched on again, or power is restored, the position can be read out. It is not necessary to move to a reference position, as it is for shaft encoders of the incremental type.

MOTOR FEEDBACK SYSTEMS

 

Hengstler offers Motor Feedback systems in all performance classes
and with the most commonly used interfaces

From modular miniature incremental encoders for DC and Stepper
Motors
in 22 mm diameter up to the absolute AC110 with 50mm
hollow shaft Hengstler provides a complete range of Motor
Feedback systems.

For asynchronous motors and elevators the offering comprises
incremental and absolute hollow shaft encoders in singleturn and
multiturn versions. Trend-setting is the Incremental OptoAsic with
diagnosis system and integrated interpolation electronic which is for
the first time used in RI80-E. This enables resolutions of up to 200 000
pulses for good synchronism of electric machines running at low
revs.

For AC Servo Motors there is an extensive range of feedback
products available: Brushless resolvers size 10, 15 and 21 uniquely
robust and low priced, incremental comcoders for direct block
commutation of BLDC motors in low cost modular version or with
integrated bearings and resolutions up to 10 000 pulses per
revolution.

Your application requires highest precision and dynamics? Than you
are on the right track with the Sine-wave encoder S21 and the
absolute Acuro-Drive encoder. Latest OptoAsic technology and a
true geared multiturn provides obvious advantages regarding
performance and reliability. Hengstler offers the Acuro-Drives series
with the open, highspeed, digital interface BiSS. With the open
source BiSS interface the proprietary lock-in situation with absolute
motorfeedback systems is broken up with the benefit of an
increasing range of suppliers.

One Size fits all:
No matter whether your servo application requires resolvers,
incremental comcoders or absolute Multiturn encoders - the complete
range in size 15 with resolver compatible mounting is available
from Hengstler. The benefit of this is, that the B-side of the motor can be resolver style and doesn't need to be customized, depending on the feedback. The Feedback type can be selected according to
customer demands or required resolution and technology. This helps
reducing variation of parts and stock and enables improved delivery
times.
