Description

Product Overview

The KOLLMORGEN 60WKS-CE240/12PB is a high-performance, brushless servo motor designed for precision motion control applications. This motor is part of Kollmorgen’s renowned AKM™ series, engineered to deliver exceptional torque density, dynamic response, and reliability. It functions as the electromechanical workhorse in automated systems, converting precise electrical signals from a compatible servo drive into accurate rotational motion with controlled speed, torque, and position. The motor’s design incorporates high-energy neodymium-iron-boron magnets and an optimized electromagnetic circuit to provide high continuous and peak torque in a compact, low-inertia package. This makes the 60WKS-CE240/12PB particularly well-suited for applications requiring rapid acceleration/deceleration, high positioning accuracy, and smooth operation at low speeds. As a critical component in closed-loop motion systems, it enables machinery to perform complex moves with repeatability, directly impacting throughput, quality, and efficiency in demanding industrial environments.

Main Features and Advantages

High Power Density and Dynamic Performance: The KOLLMORGEN 60WKS-CE240/12PB is engineered to pack maximum torque into its compact 60mm frame. This high power density, combined with a very low rotor inertia, allows for exceptionally high acceleration and deceleration rates. This enables faster machine cycle times, improved throughput, and the ability to handle highly dynamic moves with precision, which is a key advantage in pick-and-place, indexing, and contouring applications.

60WKS-M240/22

Integrated, High-Resolution Feedback for Precision: The motor comes standard with an integrated, high-quality resolver. This “PB” designation indicates a specific feedback type, typically offering excellent accuracy, repeatability, and robustness in harsh environments. The resolver provides the servo drive with absolute position information, enabling precise closed-loop control of position, speed, and torque without the need for an external encoder, simplifying system design and enhancing reliability.

Robust Construction for Demanding Environments: Built to IP65 standards, the motor is sealed against dust ingress and water jets from any direction. This robust construction, along with features like corrosion-resistant materials, high-quality bearings, and durable connectors, makes the 60WKS-CE240/12PB suitable for use in washdown areas, food and beverage plants, and other challenging industrial settings where exposure to moisture, particulates, or cleaning chemicals is common.

Application Areas

The KOLLMORGEN 60WKS-CE240/12PB is ideal for a wide range of automated machinery requiring compact, powerful, and reliable rotary motion. Common application areas include:

Packaging Machinery: Driving cutters, sealers, fillers, and labelers that require fast, accurate indexing.
Material Handling: Powering conveyors, sortation arms, and robotic transfer units.
Factory Automation: Used in assembly robots, gantry systems, and precision positioning stages.
Food & Beverage Processing: Suitable for washdown environments in filling, capping, and cartoning machines.
Printing and Converting: Driving print cylinders, web guides, and tensioning rollers.
Semiconductor Manufacturing: In precise wafer handling and component placement equipment.
