What is cogging in linear motors?
Linear motors are generally classified by the construction of the motor’s primary part: ironless or iron core. In an ironless linear motor, the windings of the primary are embedded in an epoxy resin, whereas the windings of an iron core linear motor are mounted in an iron lamination stack. The lamination contains teeth, or protrusions, […]
AMK SPINDASYN SEZ linear drive motor — rotor is integrated with screw
The new SPINDASYN SEZ electric cylinder from AMK Automation is a ready-to-install linear drive motor system in which the rotor is pressed directly onto the screw. Featuring high and constant force, high precision and position accuracy and high energy efficiency, the closed-loop positioning and force control of the SEZ make it an suitable alternative to […]
Linear-actuator application example: New angle on wheelchair vehicle accessibility
Kneeling systems have become widespread on custom wheelchair-accessible vehicles from BraunAbility and other accessible-vehicle converters. Here linear actuators lower vehicles’ rear suspension to reduce the incline angle of wheelchair ramps for easier access. Because the actuators typically mount under the vehicle chassis, they must be rugged. “Our vehicles typically kneel 2.5 to 3 in. We […]
Synchronous belt failures: Six ways they can occur
Synchronous belts can transmit high torque without the potential for slip, due to positive engagement between the teeth of the belt and the grooves of the pulley. But the performance of synchronous belt drive systems can be affected by installation errors, unexpected application conditions, or the use of components that aren’t suitable for the operating […]
Pulley balancing for belt drive systems: Is it always necessary?
As a pulley rotates, centrifugal forces act on the pulley, and if its mass is not evenly distributed around the axis of rotation – that is, if it is unbalanced – these centrifugal forces will also be unbalanced and cause the pulley to vibrate. (Uneven mass distribution can be due to imperfections in machining or […]
Gen 2 linear slide actuators from AutomationDirect
AutomationDirect has added second generation (Gen 2) linear motion slide actuators to its SureMotion line of motion control products. The SureMotion lineup includes both motor-ready actuator assemblies and an assortment of sliding components and accessories to provide a wide variety of motion control solutions for X-Y and X-Y-Z positioning systems. The new Gen 2 Compact […]
Roller pinion system in corrosion-resistant stainless steel from Nexen
Nexen Group, Inc. introduces a stainless steel version of its patented precision roller pinion system (RPS). The Nexen RPS engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. The system is also extremely quiet, and 99 % efficient. Stainless steel makes the system extremely corrosion resistant, with a long life […]
What’s the difference between a piezo actuator and a piezo motor?
In the context of motion control, the term “motor” generally refers to a single electromechanical device that produces rotary or linear motion to drive a system, while the term “actuator” typically refers to an integrated mechanical system that is driven by a motor. But in the context of piezo drives, the term “actuator” refers to […]
Enhanced online product tool from Thomson speeds linear motion component sizing and selection
Thomson Industries, Inc., has enhanced its Linear MOTIONEERING® product sizing and selection tool for linear motion systems, reducing the time for component selection from hours to typically less than 15 minutes. The tool retains the powerful Thomson engineering calculations that have proven so effective for design engineers and has added new product families, interactive navigation, […]
