Key Features of the PowerFlex 755T Series](https://blog.hesconet.com/what-is-totalforce-technology-key-features-of-the-powerflex-755t-series-1).* The four 755T variants—TS, TL, TR, and TM—all share the same TotalFORCE foundation. The differences come down to power topology, harmonic performance, and system architecture. Here's how we categorize each one. ## PowerFlex 755TS: The Six-Pulse All-Rounder The 755TS is the first standard industrial six-pulse drive with full TotalFORCE technology, and the most broadly applicable model in the family. It covers everything from conventional VFD applications to demanding motion control requiring precise speed, torque, and positioning, with wall-mount solutions available up to 500 Hp for space-constrained installations. **Best for:** general VFD applications, facilities modernizing legacy drives, and advanced motion control, particularly where harmonic mitigation or regeneration isn't required. ![](https://blog.hesconet.com/hs-fs/hubfs/undefined.jpeg?width=461&height=259&name=undefined.jpeg) ## PowerFlex 755TL: Low Harmonic, High Power Factor The 755TL uses active front-end (AFE) technology to deliver built-in harmonic mitigation and power factor correction, keeping total harmonic distortion at or below the 5% threshold required by IEEE 519, without external filters or auto-transformers adding cost and complexity. **Best for:** facilities with sensitive electrical infrastructure, strict utility power quality requirements, or environments where harmonic distortion is already causing problems for other equipment. ![20g-powerflex-755tl-drive-straight](https://blog.hesconet.com/hs-fs/hubfs/20g-powerflex-755tl-drive-straight.jpg?width=343&height=295&name=20g-powerflex-755tl-drive-straight.jpg) ## PowerFlex 755TR: Regenerative Energy Recovery The 755TR builds on the 755TL's active front-end technology and adds full regenerative capability: returning 100% of braking energy to the incoming power supply rather than dissipating it as heat. This eliminates braking resistors and all associated cooling equipment, wiring, and maintenance costs. In high-cycle braking applications, the total cost of ownership difference compared to resistive braking can be substantial. **Best for:** cranes, hoists, centrifuges, winders, test stands, and any application with significant braking energy or high-cycle deceleration demands. ## PowerFlex 755TM: Common Bus Multi-Motor Systems The 755TM takes a fundamentally different approach to multi-motor applications. Rather than supplying AC power independently to each drive, multiple inverters share a common DC bus, meaning decelerating motors feed energy directly to accelerating motors without routing it back through the incoming supply. The result is reduced system energy consumption and a dramatically simplified installation with less cabling, fewer protective devices, and no need to wire AC power to each drive individually. **Best for:** multi-axis machines, coordinated conveyor systems, and process lines with mixed motoring and regenerating loads, particularly where minimizing installation footprint and cabling complexity are priorities. ## Shared Specifications All four 755T models share the following: ## Which Drive Is Right for You? ## Making the Right Call The right 755T model isn't always obvious from spec sheets alone; the difference between the TS and TL, or the TR and TM, often comes down to application details that aren't captured in a power range or voltage rating. Getting the decision right up front saves significant time, cost, and frustration down the road. At HESCO, we've helped customers across a wide range of industries navigate exactly this decision, and we support customers through the full lifecycle: from initial specifications through startup commissioning and beyond.
