Energy-efficient VSDs, VFDs, and inverters

Gain full control of your motor applications with Emotron and Lenze variable speed drives (VSD), variable frequency drives (VFD), AC drives, and inverters. With direct torque and vector control, our VSDs are made for crushers, mills, and centrifuges. They’re also ideal for variable torque loads such as compressors and blowers. The continuous motor speed adaptation reduces energy consumption and wear while their monitoring functionality prevents damage and downtime, lowering carbon emissions and maintenance costs. The robust and intuitive design of our drives makes them easy to operate and install.

FCR Motion offers a range of VSDs, variable frequency drives (VFDs), and inverters designed to optimise both motor performance and energy efficiency. The range currently includes: 

FCR Motion’s range of VSDs and inverters are part of a broader range of products designed to complement our catalogue of industrial motors

FCR Motion’s VSDs cater to a wide range of industrial applications such as: 

  • Cranes and hoist machines 
  • HVAC systems
  • Oil & gas industries 
  • Water and wastewater treatment plants 
  • Fans, pumps, and compressors 
  • Refrigeration systems 
  • Conveyor systems 
  • Elevators and escalators 
  • Mining operations
  • Renewable energy systems… and more 

If you have a specific VSD application in mind, contact us and a team member will guide you through the suitability of our VSDs to accommodate your needs. 

To select a VSD suited to your application needs, a few key considerations to follow include: 

  • Determining the exact motor power and voltage required by your application. 
  • Identifying the characteristics of the load, whether it’s a constant-torque load, variable-torque load, or a shock (impact) load. 
  • Specifying the environment in which the motor equipped with a VSD will operate in. Conditions such as temperature, moisture, dust, and presence of gas may impact VSD functionality. A VSD with a higher  IP rating, such as IP66 may be better suited then. 
  • Confirming the required speed range and specific control requirements. 
  • Choosing a VSD that’s easy to integrate within your existing infrastructure and systems. 
  • Considering VSDs from reputable brands that offer warranties and reliable customer support. All of FCR Motion’s VSDs are covered under a 12-month warranty upon purchase.

First, conduct regular checks of the VSD for any physical signs of damage. Next, make sure to keep the surrounding ventilation clean as VSDs are sensitive to temperature fluctuations and dirt and debris that may accumulate within the surrounding environment. Last but not least, always remember to monitor electrical connections as loose or faulty connections may lead to hazard prone environments.

According to the Energy Institute, using a VSD to control motor systems can save anywhere between 15 to 40% of energy used in applications where the load on the system is variable. This is mostly effective within applications such as fans and pumps where VSDs are used to replace mechanical methods of output regulations.

Yes, VSDs can help improve power factor by minimising reactive power charges on electricity bills.

A VSD is designed to control the torque and speed of an alternating current (AC) motor by converting fixed voltage and frequency input into an alternating/variable frequency and voltage output. 

Within most motor-based applications, up to 70% of their lifetime cost is associated with electricity. On a mission to slash these costs, the usage of variable speed drives (VSD) across the industrial sector is being promoted in an effort to conserve energy and cut down waste.  

Electrical motor systems fitted with VSDs not only offer the advantage of reducing energy costs and minimising power consumption– but also provide precise electrical control, enabling speed modification, torque adjustment, reverse operation, unique movement options, and most importantly, improved safety through reduced heat emissions and lower noise levels.

 IP20 series (from 7.5kW to 630kW) IP54 series (from 1.5kW to 200kW). We can also supply a locally custom-built cabinet VSD with 3-4 weeks lead. Low Voltage up to 3MW is considered an Engineered Solution with 12-20 weeks lead time.

We stock Lenze VSDs, IP66 from 0.25kW up to 22kW and IP55 from 30kW to 75kW. For Emotron VSDs, we stock from 1.5kW to 200kW in IP54. We can also customise/design cabinet VSD solutions as a package up to IP66 rating (depending on the kW power range).

All VSDs and Soft Starters are manufactured in CG Drives & Automation HQ office in Helsingborg, Sweden.
