A direct drive motor is any motor — rotary or linear — in which the load is connected directly to the motor, without mechanical transmission elements such as gearboxes or belt and pulley systems. In other words, the motor directly drives the load. Direct drive rotary motors Rotary direct drive motors are often referred to […]

Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W). […]

Compact Linear Induction Motor from H2W Technologies
H2W engineers have developed a compact Linear Induction Motor (LMAA-04-01) that can generate 10.6 lbs (47 N) of force at a 15 percent duty cycle. Operating at 208 VAC 3-phase 60 Hz, the synchronous velocity of this LIM is 160 in/sec (4 m/s). The LMAA-04-01 linear induction motor was designed for high speed operation; however, […]
When is resolution important for linear systems?
Accuracy and repeatability are standard specifications that describe how a linear motion system behaves along its travel and how closely it reaches the intended position. Resolution, on the other hand, is less often included in performance data for linear motion systems, but it can be equally important as accuracy and repeatability in some applications. In […]
Linear motion designs see wider adoption of linear direct drives
Direct drives are a motion-control technology projected to see high rates of adoption in coming years, according to market research by the ARC Advisory Group. That’s due in part to an array of industries driving for higher throughput and more accurate processes. According to Brian Scott, applications engineer at Nippon Pulse America Inc., linear shaft […]
Profitable design of linear motion: Choosing between DIY or turnkey builds
Engineers building linear motion systems can use ground-up DIY approaches or purchase complete turnkey solutions. Here we explain where each tactic is most profitable. By John Brokaw and Kent Martins | Valin Corp. How should designers pick between building linear-motion designs in-house or purchasing pre-engineered assemblies? What is there to consider when determining the best […]
New linear motor designs improve speed and positioning
Linear motors enable maximum precision and dynamic performance in various motion control tasks. These include not only rapid traverse, but slow, constant speed traverse of machine heads, spindle slides, tool management systems, part handling devices and more. There are considerable cost savings to be realized when various mechanical components are replaced by simple and efficient […]
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, […]
High-speed linear actuators: What qualifies them as high speed?
Like many terms used in the linear motion industry, such as “heavy duty,” “miniature,” and “corrosion-resistant,” to name a few, there is no industry standard that specifies what constitutes a “high-speed” linear actuator. Nevertheless, there are some general guidelines that manufacturers follow when classifying and marketing their actuators as high speed. These guidelines are typically […]
