Regal Rexnord Corporation, a global expert in engineering and manufacturing solutions that power, transmit and control motion, has launched the Integrated Position Brake (IPB) by Warner Electric. This solution is the first in the market to combine a high-performance brake with an integrated position sensor, delivering space savings and enhanced functionality in a single component.
As original equipment manufacturers (OEMs) electrify and automate systems, space constraints often create packaging challenges, particularly when integrating speed or position sensors that typically require 25–35mm of axial length. The IPB has a patented design that solves this problem by combining a spring-applied, electrically released parking brake with an embedded position sensor in one compact unit.
“The drive toward electrification requires utilizing every millimeter of space to maximize power density,” said Jon Volk, Global Product Manager, Electrification at Regal Rexnord. “By eliminating the need for separate sensors and providing an output signal immune to magnetic interference, we are saving space and also providing OEMs with a more robust, reliable system that simplifies the entire assembly process.”
Key Advantages of the IPB:
● Versatile performance: Offers either a 0–5V SIN/COS analog absolute position output or a digital quadrature encoder with resolutions from 64 to 1024 pulses per revolution.
● Significant space savings: Reduces overall drivetrain length by up to 25mm, enabling OEMs to either shrink the package size or add motor windings for increased power.
● Simplified design: Eliminates the need for a separate encoder or resolver, reducing total component count.
● Superior reliability: The integrated sensor is immune to common external magnetic disturbances, unaffected by air gap variations and not reliant on rotating permanent magnets.
By integrating the sensor directly into the brake assembly, the system provides accurate and repeatable feedback without increasing system dimensions or complexity. This makes the IPB ideal for space-constrained designs where packaging efficiency and reliability are critical. Key applications and markets include farm and agriculture, forklift trucks, autonomous guided vehicles (AGVs) and compact off-highway equipment.
