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 ...

A majority of automated systems using linearmotors today rely on a rotary servo motor coupled to a ball screw,belt-drive, rack-and-pinion, or even a cam-follower mechanism which convert therotary ...

Linear induction motors (LIMs) convert electrical energy into linear thrust without intermediary mechanical transmission, rendering them ideal for applications ranging from urban rail transit and ...

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 ...

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 ...

To achieve EV potential by squeezing more functionality into a given volume, and delivering value at a compelling price point, means there are strong incentives for integrating motor and inverter.
