WHO WE ARE
For over 130 years, M.G. Newell has remained a full-service provider of hygienic equipment for the food, beverage, dairy, pharmaceutical and personal care industries. We carry a broad range of pumps, valves, tanks, fittings, and other manufacturing supply needs. Our process engineers work with customers to design and fabricate cost-effective, customized systems to fit their space requirements.
In addition to stainless steel equipment, our Newell Automation team develops full process control systems. Our controls engineers partner with our process engineers to design and build batch control, cleaning or other process parameters into your plant. When M.G. Newell develops smart production systems, Newell Automation takes the process to the next level by allowing you complete control at the touch of a button.
Our engineers build hygienic design into every system, from pump carts to valve clusters to batch, mixing or inline blending systems. For more about us, click the link below.Home

A VFD is a device that controls the speed of an electrical motor by varying the frequency and voltage of its power supply. The VFD also contains ramp-up and ramp-down capabilities to start and stop the electrical motor smoothly.
Here some reasons why we need to control the speed of an electrical motor.
- Save energy and improve system efficiency.
- Reach the desired torque or power for the process requirements.
- Lower the noise levels of pumps, blowers, fans, compressors, etc.
- Reduce mechanical stress on the machines and improve their life cycle.
Improve the working environment.
Primary Sections of VFDs
A VFD consists of 3 primary sections: the Rectifier/Converter, the DC Bus, and the Inverter.
The rectifier/converter is the first of the three sections of a VFD’s main power circuit, and first in terms of power flow. Incoming AC line voltage is rectified or converted to DC voltage in the converter section, which consists of diodes, silicon-controlled rectifiers (SCRs), or insulated gate bipolar transistors (IGBTs) connected in a full-wave bridge configuration. One rectifier will allow power to pass through only when the voltage is positive. A second rectifier will allow power to pass through only when the voltage is negative. It requires two rectifiers for each phase of power.
The DC Bus is the 2nd section of a VFDs main power circuit. The main function of this link is to store, smooth and deliver the DC voltage. The incoming power from the rectifier contains voltage ripples which is smoothed using capacitors.
The 3rd section of a VFD power circuit is the Inverter. The inverter section of a VFD is the primary difference between an AC drive and a DC driver. This section is comprised of Insulated Gate Bipolar Transistors (IGBTs) which convert the DC voltage back into AC voltage to feed the motor. IGBTs are very fast and very small semiconductor switches that are actuated electronically, thus creating a sinusoidal output current.
