Drive Systems Design:
Drive system design is a core business at Nol-Tec.
Projects range from simple stand-alone drives, to complex networked
installations with hundreds of individual drives. Our engineers are
experienced with design issues such as dynamic braking, torque proving
power dip ride-through, regenerative drives, to list a few.
Upgrade Older Drives:
Older machines that are creating high maintenance costs can be up-fitted
with new drives. Often DC motors can be replaced with AC motors and
drives to reduce maintenance costs and improve up time. Alternately, existing
motors can stay in place while the drives are replaced. Newer technology
drives offer many communications options, and provide the opportunity to
greatly simplify control wiring as part of the retrofit. In some cases this
can significantly reduce machine downtime due to problematic control wiring.
New technology drives also offer advantages in improved reliability, energy
savings and enhanced performance.
