The Drives & Motion Division of Yaskawa America, Inc. has added the Sigma Trac II series linear servo motor stages to the Sigma-7 servo family. Sigma Trac II combines a Yaskawa SGLF2 series linear motor with linear bearings, high-resolution absolute optical scale, cable management, and optional bellows to create a turnkey linear stage. Leveraging the […]
ANCA Motion expands high-performance tubular linear motor line
The LinX M-series linear motor features an integrated position sensor with 10 um of resolution, eliminating the need for an external encoder, simplifying system design and reducing overall cost. Modular design of the heatsink and end-caps enables flexibility in system integration. The motor produces a continuous force range of 90 to 160 N and a […]
Direct-drive linear motors with integrated encoders offer resolution to 1.25 µm
Moticont has added two linear motors to its SDLM Series of high-speed direct-drive linear motors. These compact drives with a 1.0 in. (25.4 mm) stroke are just 1.00 in. (25.4 mm) in diameter and 3.75 in. (95.3 mm) long. These direct-drive linear motors feature resolutions of 5 µm (0.000197 in.) and 1.25 µm (0.000049 in.) […]
Tubular linear motors for gantry applications
Linear motors are often thought of as either flat or U-channel designs. But tubular, or shaft-type, linear motors have a construction principle that provides higher efficiency and makes them especially well-suited for gantry applications. Benefits of cylindrical design Tubular linear motors consist of a thrust rod (or tube) with permanent magnets and a stator (sometimes referred […]
What are ironless linear motors?
There are two primary types of linear motors: iron core and ironless, depending on the construction of the motor’s primary part. Iron core designs produce very high thrust forces and are often found in machine tool and heavy duty transport applications. Ironless linear motors, on the other hand, have a lower mass and can produce highly […]
Primatics linear stage for long travel and high precision
Primatics PXL43B long travel linear stage is a small form factor, high precision motion stage. A linear motor and linear encoder provide precise positioning to 150 mm. Anti-creep cage cross roller linear bearings result in smooth, flat, and straight motion. The PXL43 series is ideal for use in applications for precision assembly and inspection. Its compact […]
What are the main types of linear actuators?
Updated August 2017 || Linear actuators come in myriad configurations to suit almost any application, environment or industry. They’re primarily categorized by their drive mechanism; then manufacturers use other features such as the type of guide and housing to further differentiate them. Below is an explanation of the most common linear actuator categories. Belt-driven and […]
What are iron core linear motors?
Linear motors are often classified as either ironless or iron core, referring to how their primary parts are constructed. Ironless linear motors have a primary made of windings that are embedded in epoxy resin. In iron core linear motors, the windings are mounted in an iron lamination stack. Like the rotor and stator of a […]

Frameless kit construction enables easy integration into machinery, linear stages and actuators. Built using state-of-the art magnetic designs, the Javelin Series delivers high acceleration and high speeds in compact, lightweight form factors. […]
What is linear motor commutation?
The process of linear motor commutation is not well understood and is often glossed over, but it has a significant effect on performance. Motor force (torque in a rotary motor) is proportional to the magnitudes of the magnetic fields of the magnet track (stator in a rotary motor) and forcer (rotor in a rotary motor), multiplied […]
