WEG Offers Motor Solutions in Agriculture Applications
January 11, 2021
For WEG, productivity and efficiency is important. Therefore, they have developed complete solutions, from water collection for farming to full systems for process monitoring, ensuring high performance for the farming industry.
Motor applications in the various primary segments, such as livestock, have been demanding equipment with increasingly advanced technology, which is designed and built to meet the demands of continuous service operations. This type of action, which implies frequent starts and stops, requires highly reliable motors that support the additional load imposed by the harsh environment. That is why WEG motors are designed to work in agricultural applications that require high torque performances. The growing technological need of agribusiness, connecting people and the use of highly reliable equipment, makes all the difference in the productivity of farms.
A distributor of grain processing equipment, which used a motor to drive its dryers, replaced the WEG W22 motors, suitable for heavy duty regime, and found that this line was more suited to their needs and brought more value to the application. The return on investment was so expressive that, after the change, over the past 18 months, they continued to modernize their equipment using WEG products.
The WEG motors of the W22 line offer a service factor of 1.25 hp with 100 hp, which competing products did not offer. The motor is the most suitable for agricultural applications, as it offers compatibility with “harmonics in electrical systems”, which is an abnormality in the quality of the energy being delivered to a system. These abnormalities can include low power factor, voltage variations, frequency variations and surges. WEG motors are designed to accommodate these types of problems, which can occur in agricultural applications.
The voltage imbalance occurs because farms rely on energy supplied by utilities in many different phases, and they have been dealing with this for a long time. To exemplify, in an ideal scenario, each phase should receive a current of 10 amps, however the concessionaire can supply a phase with 9.3 amps, another with 11.7 amps and another exactly with 10 amps. This variable current represents a challenge for farmers and their equipment, as they need motors that can operate efficiently without losing power.
As farms expand into larger spaces - some up to 5,000 acres - there is a need to switch to heavy duty motors, as more voltage is required, and a three-phase motor helps to reduce costs. Thus, the construction of WEG motors, compared to general purpose motors, is the best option for the type of application required by farms.
Heavy duty electric motors also offer better insulation for a higher operating ambient temperature, and are suitable for a 1:20 speed variation range. It is not uncommon for the motors to operate at an external temperature close to 100 degrees, thus, having a better insulation, it can work with a colder temperature, increasing its durability and consequently operating for a longer period of time.
General purpose and standard motors, previously used in the agricultural sector, no longer make sense for the current scenario. For this reason, WEG recommends motors such as the W22 line, with the ability to work in the most difficult conditions.
The use of agricultural equipment such as WEG products guarantees farm owners the reliability they need to operate without the risk of unplanned downtime.
