Powerful and extremely miniaturized With the new MC3001 motion controllers, available as MC 3001 B (board-to-board connectors) or MC3001P (28-pin plug connector), FAULHABER rounds out the MC V3.0 generation of controllers at the lower end of the performance spectrum. The controllers are extremely miniaturized and, with 1.4 amperes in continuous operation and up to 5 amperes peak current, are very powerful. They are designed as slaves for control and positioning tasks of DC micromotors, linear DC servomotors or brushless DC motors.

Top Application: What's a sapphire piston used for -- and who can make one? If you want a prototype piston made of metal for research purposes, you have a lot of options -- you can even 3D print your own. But what if you need something much more exotic, like the second-hardest natural material? When Mid Michigan Research had just such a need, it turned to Insaco for the company's long history of custom fabrication of precision parts made from ultra-hard materials, often in unusual forms.
