Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

Machine and robot builders recognize linear motor benefits, but some are reluctant to integrate the components into design because of incomplete understanding of the technology. Here we overcome that ...

Moticont's brushless miniature DC linear voice coil motor is built with haptic feedback efficiency for medical/surgical instruments, vibration damping, laser machining, packaging, wafer handling, and ...

The linear voice coil motor (aka linear DC motor) is guided by a long-life plain bearing that can allow side loads up to 3 lb (13.5 N), while the precision ground 0.236-inch (6.0 mm) diameter shaft ...

Precision automation systems and instrumentation equipment manufacturers depend on motion components in applications from micro-mechanical assembly to optical scanning. PI offers a wide range of ...

When most engineers hear the term motor they most-naturally think of rotating arrangements such as brushed DC, brushless DC, stepper, or variable-frequency prime movers. But a motor doesn’t have to be ...

In applications demanding precision and throughput, linear motor production systems usually need to be built from the ground up. Fractional microns accuracy requires feedback from an optical encoder, ...

Once considered expensive and exotic, linear motors are at last becoming valuable workhorses in a variety of OEM applications. Besides delivering nanometer precision in the semiconductor and machine ...

We admit that this project doesn’t have very many details available, but it was just too neat for us to pass up. It’s a small linear motor which [ligonapProduktion] built after seeing a very brief ...

In the next few weeks, linear motors will face their ultimate litmus test. After years in the eye of a swirling technical storm, surrounded by doubters who say they're too expensive, supported by a ...

We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment ...
