Variable frequency drive Triol AT24 Multidrive


I salute the readers of my blog. I decided to extend it and write about our new equipment Triol AT24 Multidrive.

Let’s imagine the enterprise that is equipped with several electric motors, which control pumps, funs and conveyors. Good example of such case is a drilling rig, which involves drawwork motors, rotor, brake resistors, pumps, etc. It is quite necessary to control all of these motors to manage technical process.

How to do it?

You have to buy special equipment (variable frequency drive, reduced-current starter or other) for each motor. But it is not so easy to do, because each motor has its own power setting and type of load. And how in such case will you organize the control over all these equipment and accommodate it?

Triol Corporation has found solution to this issue! It is Triol AT24 Multidrive – a variable speed drive that controls several motors simultaneously.

This equipment accomplishes the following operations: start, acceleration, deceleration, stop and control of motor rotation frequency with given parameters. Also it ensures dynamic braking and reverse, if so required.

Triol AT24 Multidrive controls mechanical brake and protects motors from short circuit currents and overloads.

Fundamental distinction of Triol AT24 Multidrive from other variable speed drives is that power supply of separate output voltage source inverters comes from common direct current link (DC link). Such configuration guarantees the high efficiency of equipment due to power interchange between separate drive motors through the power contour of inverters and DC link.

Structurally variable speed drive Triol AT24 Multidrive is a set of cabinets, which are organized by modular-assembly principle. Such construction allows not only to simplify the drive system entirely, but also to enhance reliability and save space.
