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 ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

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 ...

Since the beginning of the coronavirus crisis at the latest, the pharmaceutical industry and laboratories have been under pressure to realize the highest possible levels of automation. Necessary here ...

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 ...

The design of different three-phase brushless DC motors and how they generate torque. How magnetics, construction, and other factors impact torque, speed, and smoothness in BLDC motors. General ...

As is ever the case with engineering design, the primary trade-offs occur between power (energy), performance (efficiency), and area (miniaturization). While this is especially true in designing ...
