WEG Drives

WEG offers Brazilian designed and US market supported drives. They have a whole family of drives consisting of nine different series! Each series is designed for better function with certain types of applications. Here are a few of the most popular options!

CFW11 Series

This series is WEG’s go-to solution for low-voltage drives. These drives are very versatile, the rating is split between Normal Duty (Variable Torque) and Heavy duty (Constant Torque).

Normal Duty is 150% for 3 seconds every 10 minutes or 110% for 60 seconds every 10 minutes.

In Heavy duty mode (CT) rated is 150% for 60 seconds every 10 minutes or 200% for 3 seconds every 10 minutes. When in Heavy Duty mode the drive is compatible with 1.5-1000 HP motors. CFW11 series has many other options that are customizable to your specific application.

CFW700 Series

This series is geared towards universal applications but is designed to work best with fan or pump applications that have variable torque loads. With dual DC BUS chokes built in an AC line reactor is not always needed.

CFW701 Series

The CFW701 series lends itself to industries that utilize HVAC and refrigeration systems. 4 programmable isolated open collector outputs, and 2 non-isolated programmable analog outputs. If you have HVAC needs, this might just be the drive for you.

CFW8 Series

This is WEG’s only washdown rated VFD which makes it perfect for food, beverage, or pharmaceutical industries. The temperature ratings for these drives are great for hot or cold extremes, rated from 14°-122°.

EDP11 Series

WEG offers a fully engineered drive panel. The EDP11 series has two enclosure types, NEMA12 or NEMA3R, making it the complete package for multiple styles of applications. The drive panel can be fitted with/without a three-contactor bypass making any WEG drive an option if the VFD is down or being serviced. 

Geared Motors

WG20 Geared Motors

The first geared motor range to be completely developed in-house at WEG is the WG20 line. These two-stage units have a large ratio range allowing them to flexibly adapt to applications. Thanks to the sophisticated design these motors are incredibly efficient. High strength to weight aluminum housings of WG20 geared units provide a highly versatile and reliable product. Comprised of helical, parallel shaft, and helical bevel gear units with torques between 50 and 4500 Nm, WG20 geared motors provide a wide range of possible applications. WG20 Geared Motors options, depending on motor, are offered with:

  • 2 to 3 stages
  • 12 – 30 kW of power
  • 50 – 4500 of torque
  • 44 – 487.67 ratio
  • Helical geared (C)
  • Parallel shaft (F)
  • Helical bevel (K)

MAS Geared Motors

WEG geared motor components are 100% vertically integrated. The latest plant, machinery, and quality management system is certified to ISO 9001. This certification maximizes customer benefits by delivering high flexibility, extreme precision, and outstanding reliability. WEG has earned itself a reputation for distributing essentially indestructible geared motors. MAS Geared Motors options, depending on motor, are offered with:

  • 12 – 90 kW of power
  • 17 – 20,000 Nm of torque
  • 3 – 18,800 ratio
  • Parallel shaft
  • Helical bevel
  • Helical worm
  • Worm

Gearboxes

Input Shaft

Gear designs with an input shaft unit make it possible to operate the MAS gearboxes via added drive elements such as couplings, belt or chains. An economical solution if the input motor cannot be assembled directly next to the gear unit is a WEG gearbox.

Motor Adapters

Thanks to their structural design, parallel shaft gear units are particularly suitable for conveyor technology applications. All four sizes can be fitted with either a hollow shaft, output shaft, mounting flange or shrink disc. The ratio range of gear unit sizes F04 and F05 can be extended by a third gear stage.
