High-frequency (HF) noise from Welding Machines is notorious for disrupting motor Drives (DC Drives & VFDs) and sensitive electronics like: Computers, CNC machines, PLC’s, etc. Since input power & output filters and shielded wire do not generally solved it, the noise is likely entering through the control signals wires, Armature & Field wires output side, or improper grounding.

En cualquier entorno donde sea necesario controlar la velocidad o el par de motores de corriente continua, nuestros controladores ofrecen una solución confiable y eficiente.

Además, los controles de velocidad de CC pueden reducir significativamente los costos operativos de las máquinas. Los Controles Regenerativos de CC representan una alternativa económica a los servo-accionamientos, permitiendo su uso con retroalimentación por Armadura o Taco-generadores.

REGENERATIVE DC Drives can be used instead of servo drives & motors in most appilications, and they are cheaper than Servo Equipment.

Regenerative Reversible Speed Controls electronically manage DC motors (1/4-7.5 HP, 90-180V), offering precise speed and direction control. Their key benefit is "regeneration", which means they save energy by feeding power back to the grid when the motor slows down or stops. This also eliminates the need for mechanical parts, simplifying systems and reducing maintenance. With "four-quadrant operation," they can provide full power in both directions, making them a cost-effective alternative to servomotors in many applications.

DC motor drives offer a practical solution for conveyors because they provide full torque from as low as 1 RPM all the way to full speed, are generally more affordable, and are easier to work with. In many applications, regenerative-reversible DC speed controllers can also be used to run the motor in both directions—eliminating the need for more complex and expensive servo systems. This makes DC drives especially suitable for applications that require frequent starts, stops, or directional changes without sacrificing torque or control.

DC Drives & DC Motors Deliver

Superior Performance

·         High Starting Torque: DC motors, especially series motors, provide starting torque up to 500% of rated torque, making them ideal for heavy-load applications like extruders, mills, trains, presses, and cranes.

·         Wide Speed Control Range: They allow precise speed control both above and below rated speed using armature or field control methods, widely used in industries like rolling mills and paper mills.

·         No Harmonic Issues: Unlike AC motors, DC motors are free from harmonic effects, reducing inefficiencies and extending motor lifespan.

·         Fast & Accurate Control: Perfect for applications requiring quick start, stop, and reverse operations.

·         Cost-Effective & Simple: DC drives require minimal electronics and are less complex than AC drives, saving on operational and maintenance costs.

DC Motors remain the best choice for applications demanding flexibility, reliability, and precision.
