Ok, here's one of those smaller units I was talking about. These are basically brushless stepper motors that are driven off of a brushless controller that is slaved to either a PC, or a PLC.
This one is one of the smallest one's we get to work with. These motors also act as positioning devices for manufacturing, etc. and are used for indexing stuff for robotics, etc. They replace complex mechanical positioning devices of yesteryear.
Here is one of the larger ones we work with. This is the one that almost wrenched my hand off!! After reading the 2HP rating on the nameplate afterwards, I really felt like an idiot!!
Here is the LVD-5 brushless controller. This unit is one of the smaller ones made. It is rated at 5 amps continuous at 110 volts. This unit can be controlled remotely via a PC realtime, -or even operate off of a PLC remotely.
