For one manufacturer of CNC grinding machines, new high-performance linear motors replaced ball-screws and improved machine performance. It’s no secret that linear motors are highly effective motion devices. Linear motors can achieve high acceleration rates and long travel lengths with good thrust forces and extremely high positioning accuracies, while other drive mechanisms, such as belts, […]

Linear electric motors designed specifically for machine tools
NUM has launched a series of brushless linear servo motors designed specifically for continuous duty cycle applications in machine tools. NUM’s new LMX series linear motors incorporate a number of features to help mitigate the effect of arduous operating conditions. Their moving coil primary section is fully encapsulated in a robust stainless-steel housing, with an […]
Tubular linear motors from ANCA Motion offer drop-in replacement for ball screw systems
Like other tubular linear motors, ANCA Motion’s LinX M-Series is designed to be close in form to ball screw systems, offering easy substitution for those who want to make the change. Both cylindrical linear motors and flatbed linear motors have superior accuracy and repeatability compared to ball-screw options. A tubular linear motor is also a […]
Magnetically preloaded single-axis linear stepper motors from H2W
H2W Technologies’ single axis linear stepper motors are suitable for high-speed open-loop positioning applications. They can perform at speeds of up to 80 in./sec [2 m/sec] and strokes of up to 68 in. [1.7 m]. Linear stepper motors are capable of precise position, velocity, and acceleration control when coupled with a micro-stepping drive and indexer. […]
New 20-mm linear stepper motors from Nippon Pulse
Nippon Pulse has introduced its smallest linear stepper motor yet, the PFL20 Linearstep. The PFL20 is a highly efficient, high thrust tin-can linear actuator with a 20-mm diameter and a bipolar winding. The PFL20 is RoHS-compliant, has a 30/60 mm effective stroke, and can reach 6 N of force at 200 pps. With 24 steps […]
New generation of linear motor stages from Yaskawa
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 main 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 […]
