Torque limiters are mechanical and electromechanical power-transmission devices that protect machine sections (or workpieces they’re servicing) from overloads, crashes, and damage from jams. Torque limiters work either by slipping or completely disconnecting the drive from the driven load. Some torque limiters of the former type (especially those employing friction plates) are also called slip clutches. […]
What is safe motion monitoring?
Machines and equipment placed on the European market must conform with essential health and safety requirements of the Machinery Directive. The Directive specifies that manufacturers of machines and equipment must conduct a risk assessment and implement measures to eliminate or reduce hazards that pose a risk to people, equipment, product, or the environment.

Getting servo motor and drive phase and commutation alignments right
Addressing issues related to commutation alignment between AC PM servo motors and servo drive amplifiers — especially when motor and drive are from different manufacturers — can be quite challenging. Here we outline how to make that easier. By Hurley Gill • Senior applications and systems engineer | Kollmorgen In this article, we’ll start by confirming […]
Merger of two existing product lines: Dorner’s FlexMove conveyors
Dorner has consolidated two existing product lines and unified them into a single platform, which is now called FlexMove. While the FlexMove name isn’t new to Dorner, it now incorporates the features and strengths of the former SmartFlex conveyor line. The FlexMove flexible chain conveyor brings the best engineering and performance standards in flexible conveying […]
Motion-failure alarm from Siemens supports commissioning and configuration
Siemens now sells a Sitrans WM300 motion failure alarm (MFA) to detect changes in the motion and speed of rotating, reciprocating, or conveying equipment. This alarm acts as an early warning system for a plant’s machinery, alerting users to potential problems in their operations before they occur or develop into something more serious. This versatile […]
