LS Electric Variable Frequency Drives for Industrial Motor Control
As an authorized partner of LS Electric, Cordyne supplies LS Electric VFDs and builds them into finished drive panels at our Houston facility. You can source an LS Electric variable frequency drive as a component or as a wired, tested assembly built to your drawings. Either way, our engineers confirm the drive against your motor and supply voltage before anything ships. Plant engineers and procurement teams get one source for the drive and the panel around it. We also supply LS Electric medium voltage switchgear and switchboards.
LS Electric VFD Series Cordyne Supplies
LS Electric builds its low-voltage drive line for specific duty types. Start with the load, then match the series to the application.
- The M100 and G100 handle compact machine control and general-purpose duty.
- The S100 adds sensorless vector control and permanent-magnet motor capability. It includes safe torque-off and offers an IP66/NEMA 4X option for washdown and contaminant-heavy areas.
- The H100 targets fan and pump duty in HVAC and water treatment.
- The iS7 handles high-performance applications that need precise torque control.
- The SP100 provides an integrated bypass package for critical fan and pump systems.
Modbus RTU is standard on most models, and additional protocol cards vary by series. Give us your plant network requirements at the quote stage so we include the correct option card in the build.
What a UL 508A Panel Shop Adds to an LS Electric VFD
A loose drive still needs an enclosure and field wiring. We fabricate enclosures in-house, so we design the drive layout around the enclosure that houses it, rather than fitting it into a stock box. We build NEMA 1, 3R, 4X, 7, 9, and 12 enclosures, including NEMA 7 explosion-proof configurations for Class I, Division 1 and Division 2 areas.
Our engineers review motor nameplate data and duty cycle against the drive rating, then compare the enclosure to the installation environment. We coordinate ratings between the motor and the drive so each device in the circuit carries the correct classification.
We wire and label each assembly, then functionally test it before it ships. We also provide submittal drawings and test documentation for project approval.
For retrofits, we cross-reference your existing drive to a current LS Electric part number. We then configure the replacement to match the footprint and control interface, where possible.
We carry inventory on commonly specified LS Electric components and order project-specific items as needed. Lead times vary by line and configuration, so send us your bill of materials and required delivery date. We will confirm availability against your schedule.
Where Engineers Specify LS Electric VFD Drives
The applications below account for most of the assemblies we build.
- Industrial Machinery: Conveyor drives and process pumps where drive uptime sets line output.
- Oil and Gas: Drilling systems and injection pumps, often in classified areas that call for explosion-proof enclosures.
- Petrochemical and Refining: Process control panels and motor control assemblies for continuous-duty operations.
- Marine and Offshore: Vessel and platform control systems that face vibration and salt exposure.
Certifications Behind Our LS Electric VFD Assemblies
In addition to being a UL 508A-certified panel shop, we hold UL 698A and UL 1203 certifications, along with ISO 9001:2015 certification.
These credentials cover the finished assembly. Assemblies built with LS Electric components comply with applicable UL and CSA standards, as well as the NEC. Our quality assurance process maintains the documentation and traceability required by regulated projects.
LS Electric maintains UL and cUL listings across its drive lines, so confirm the listing for your catalog number during specification. We will include the applicable documentation with your quote.

Frequently Asked Questions About LS Electric VFDs
A VFD controls motor speed across its full operating range. A soft starter only ramps voltage during startup, then runs the motor at full speed. Choose a VFD when the process needs speed control or energy savings from slower running. Choose a soft starter when the motor runs at a fixed speed and you need to limit inrush current. Cordyne supplies both from the LS Electric line, and our engineers can size either one to match your load.
On a centrifugal fan or pump, power draw falls with the cube of speed. Running at 80 percent speed uses roughly half the power of full speed in the ideal case, because 0.8 cubed is about 0.51. Drive and motor losses trim that figure in practice. Savings also shrink on systems with high static head and on loads that run near full speed most of the time. Tell us your typical operating speeds when you request a quote, so we can size the drive to your duty cycle.
LG Industrial Systems became LS Industrial Systems (LSIS) in 2005 and adopted the LS Electric name in 2020. Older nameplates and manuals may show an earlier name, but the manufacturer is the same. LS Electric is based in Anyang, South Korea, and LS Electric America serves as its North American subsidiary.
