Top 5 VFD Drive Brands That Sell Fastest as Surplus

When it comes to selling surplus Variable Frequency Drives (VFDs), knowing which brands move quickly can save you time and maximize your return. As someone with over 30 years of experience in industrial surplus equipment — specifically VFD drives — I’ve seen firsthand which manufacturers consistently attract strong buyer demand and premium prices. In this comprehensive post, I’ll share the top 5 VFD drive brands that sell fastest as surplus, backed by real market data, industry specs, and practical advice to help you sell your drives efficiently and profitably.

Why Brand Matters in Surplus VFD Sales

Before diving into the top brands, it’s important to understand why the brand of a VFD significantly impacts its resale speed and value. VFDs are complex electronic devices used to control AC motor speed and torque by varying motor input frequency and voltage. Reliability, performance, and ease of integration are key factors that buyers look for, especially when purchasing surplus units.

Buyers in industries like manufacturing, water treatment, HVAC, and oil & gas rely on proven brands that meet industry standards such as UL, CE, and sometimes NEMA ratings. Drives with known quality, documented support, and widely available parts tend to sell faster. Additionally, certain brands dominate specific market segments or voltage ranges, making them more desirable.

Top 5 VFD Drive Brands That Sell Fastest as Surplus

1. Allen-Bradley (Rockwell Automation)

Allen-Bradley is arguably the most sought-after VFD brand on the surplus market. Their PowerFlex series, especially the PowerFlex 4, 40, and 70 models, are known for exceptional build quality, integration with Rockwell’s PLC and control systems, and extensive communication protocol options (EtherNet/IP, DeviceNet, Modbus).

Typical specs for PowerFlex 40 drives range from 0.5 HP to 150 HP at 480 VAC, making them versatile for a broad range of industrial applications. Prices for used PowerFlex 40 drives in good condition typically range from $300 to $1,200 depending on size and features.

With over 30 years in the field, I’ve noticed PowerFlex drives consistently sell within a few days to a couple of weeks after listing, especially with complete accessories like operator panels.

2. Siemens

Siemens VFDs, particularly the Micromaster and Sinamics series, are prized for their durability and advanced motor control capabilities. The Micromaster 440, for example, supports 0.25 kW to 250 kW (0.33 HP to 335 HP) at 230/400V and features built-in PID control and safe torque off (STO) functions, which are critical for modern industrial safety standards.

Surplus Siemens drives have a strong following in automation-heavy sectors. Expect resale prices from $400 to $2,500 depending on the model and condition. Due to their modular design and wide usage in Europe and North America, Siemens drives often sell within 10 days on average.

3. Yaskawa

Yaskawa’s GA700 and V1000 VFD series are globally recognized for their efficiency and ease of use. The GA700, with power ratings from fractional HP to 200 HP, offers dynamic braking, built-in EMC filters, and compatibility with various motor types including synchronous and induction motors.

Yaskawa drives benefit from a reputation for ruggedness, often lasting 10+ years in harsh industrial environments. Surplus Yaskawa VFDs generally sell quickly, with prices ranging from $350 to $1,800, depending on size. Their robust design and worldwide support network make them very attractive to buyers.

4. ABB

ABB’s industrial drives, particularly the ACS355 and ACS580 series, are known for energy efficiency and flexible connectivity. The ACS580 supports a voltage range of 200-690 VAC and power ratings from 0.75 kW to 630 kW (1 HP to 850 HP), making it suitable for both light and heavy industrial loads.

ABB’s global reputation for quality and innovation ensures their surplus drives command premium prices, often between $500 and $3,000. ABB drives also feature integrated energy-saving functions and advanced diagnostics, making them popular in energy-conscious industries.

5. Schneider Electric

Schneider’s Altivar series, particularly the Altivar 312 and 61 drives, are widely used across commercial and industrial sectors. The Altivar 61 offers power ratings up to 250 kW and supports multiple control modes including sensorless vector control, which enhances motor performance.

Schneider drives are favored for their user-friendly interfaces and comprehensive software support. Surplus units sell well, with prices ranging from $300 to $2,200. They are especially popular among HVAC and water treatment system buyers.

Practical Tips for Selling Your Surplus VFD Drives

Knowing the top brands helps, but how you present and price your surplus VFD drives can make a big difference in how fast they sell. Here are some practical steps to maximize your sales success:

• Accurately Identify Model and Specs: Always provide full model numbers, input/output voltage, current ratings, horsepower, and communication options. For example, “Allen-Bradley PowerFlex 40, 10 HP, 480 VAC, Ethernet/IP” is far more appealing than simply “PowerFlex drive.”
• Test and Document Condition: Buyers prefer drives tested to confirm operational status. If you can run a functional test and provide test results, you will attract more interest. Also note any cosmetic damage or missing accessories.
• Include Manuals and Software: Supplying user manuals, wiring diagrams, and parameter-setting software increases buyer confidence. Many VFDs require software for programming, so these add significant value.
• Price Competitively but Realistically: Research recent sales of similar models on online surplus marketplaces and auction sites. Undercut slightly to accelerate sales but avoid pricing too low, which may raise doubts about quality.
• Highlight Industry Certifications: Mention UL, CE, IEC, or NEMA ratings as applicable. Drives certified to recognized standards are more desirable.
• Package and Ship Securely: VFDs are sensitive electronic equipment. Proper anti-static packaging and secure crating will prevent damage and returns.

Understanding VFD Grades and Specifications

When evaluating or selling surplus VFDs, it helps to understand grades and key specifications:

• Input Voltage: Common VFD input voltages are 230 VAC single or three-phase, 460/480 VAC three-phase, and 575 VAC. Drives rated for 480 VAC three-phase are the most commonly used in heavy industry.
• Power Ratings: VFDs are rated by horsepower (HP) or kilowatts (kW). For example, a 15 HP drive typically handles 11 kW motors. Confirm that the drive’s continuous current rating matches or exceeds the motor nameplate.
• Enclosure Ratings: NEMA 1 (indoor), NEMA 12 (dust-tight), or NEMA 4/4X (water-resistant) ratings impact where the drives can be installed, influencing buyer interest.
• Control Methods: Scalar (V/Hz), vector, sensorless vector, and flux vector control modes affect performance and suitability for precise applications.
• Communication Protocols: Ethernet/IP, Modbus RTU/TCP, Profibus, and DeviceNet are common interfaces that allow integration with PLCs and SCADA systems.
• Safety Features: Many modern drives include Safe Torque Off (STO) and Safe Stop functions certified to IEC 61508/ISO 13849 standards, increasing their resale appeal.

Frequently Asked Questions (FAQs)

1. What factors most affect the resale value of surplus VFD drives?
   The brand, model, power rating, and condition are key. Drives from reputable manufacturers like Allen-Bradley, Siemens, and ABB command higher prices. Functional testing, availability of manuals, and complete accessory bundles also increase value.
2. How important is it to provide the drive’s communication protocol information?
   Extremely important. Buyers need to confirm compatibility with their control systems. Protocols like Ethernet/IP, Modbus, and Profibus are common. Drives without documented communication options sell slower and for less.
3. Can older VFD models still sell well as surplus?
   Yes, but with caveats. Older models from top brands that are still supported or have widely available parts can sell quickly. However, very outdated or discontinued lines without support may have limited market appeal.
4. Do I need to test VFDs before selling them?
   Testing is highly recommended. Functional confirmation reduces buyer risk and speeds sales. If you lack testing equipment, consider partnering with a surplus buyer who can handle testing and refurbishment.
5. What is the typical turnaround time to sell a surplus VFD drive?
   For popular brands and models in good condition, sales typically happen within 1-3 weeks. Drives from less recognized brands or in poor condition may take longer or require price adjustments.
