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.

Hengstler presents the shortest hollowshaft encoder world wide: The AD35. It is available with a 8 mm hub shaft and and a resolution up to 22 Bit Singleturn. The mechanical design consists of two ball bearings and a flexible torque support. The AD35 complements the ACURO-DRIVE series and is appropriate for use within BLDC servo motors with small frame sizes. Further fields of Application:

  • Medical
  • Measuring instrument
  • Military
  • Robotics
Fully digital control loop:

The new and completely digital OptoAsic technology enables the transition to a truly digital drive system. The conventional absolute encoders still have analog sine wave signals for the feedback of speed and position data. The AD35, however, provides fully digital position data up to 22 Bit over the BiSS interface with a variable clock rate up to 10 MHz. BiSS is the only open high speed bidirectional sensor interface available on the market. Backward compatibility to most of the existing drives is realized through the variant with SSI interface together with 2048 sine −cosine periods per revolution.
Integrated diagnostic system

The AD35 has an integrated diagnostic system that controls and regulates the internal signals. Maximum motor uptime is achieved through the pre warning in case of any system error or aging effects well before they affect the function of the encoder. A code plausibility check guarantees that the output data represents always the true position. Also the operating temperature can be measured and read out with 8 Bit resolution. If programmable limits are exceeded or under run this is indicated over warn and alarm bits.
