Schneider Electric offers a wide range of fully tested, ready-to-connect motor control solutions including variable speed drives (VSDs) and soft starters. From compact, pre-engineered systems to custom-engineered solutions, our drives are built to the highest quality standards and tailored to fit diverse applications across all market segments.
A variable speed drive is an automation component that controls the speed and torque of an electric motor. By precisely adjusting motor performance, variable speed drives improve efficiency, connectivity, repeatability, and maintenance outcomes in processes such as packaging, material handling, machining, and hoisting.
How variable speed drives work:
- Regulate motor speed, torque, and position by controlling the power supplied to the motor
- Enable rapid starts/stops with appropriate fluxing and motor current
- Support manual, automatic, or remote operation for flexible control
VSD vs. VFD vs. AC drive — what’s the difference?
- VSD (Variable Speed Drive): Umbrella term covering both AC and DC motor speed control
- VFD (Variable Frequency Drive): A type of VSD specifically for AC motors; adjusts motor speed by changing supply frequency
- AC Drive: Controls the speed of an AC motor to enhance process control and reduce energy consumption
Benefits of variable speed drives:
- Extends motor life through smoother starts/stops and reduced mechanical stress
- Stabilises power and mitigates inrush currents and surges
- Delivers adjustable speed and acceleration for precise process control
- Provides dynamic torque control and smooth motion for lifts, escalators, and conveyors
- Lowers peak energy demand and reduces consumption when full power isn’t required
Choose Schneider Electric variable speed drives to optimise energy use, enhance process performance, and increase equipment reliability—backed by scalable hardware, intuitive software, and global support.
