SOFT STARTER
Features:
- Pure sinusoidal voltage control rather than chopped waveforms reducing motor stress.
- Advanced air-core / magnetic core series-reactor (HFSR™ / FCMA™) technology for low-harmonic, high-quality performance.
- Closed-loop PLC control with built-in sensors monitoring torque, current, PF, and motor dynamics.
- Robust panel options (including IP67 for outdoors) and strong safety features (fault detection, interlocks, monitoring)
- Dedicated manufacturing capacity, high rigor in quality assurance, and global installation base (8,000+ sites)
Applications: These soft-starters are designed for heavy industrial use, including:
- Pumps (irrigation, de-watering, cooling towers)
- Fans and blowers (ID/FD fans in steel, chemical, and power plants)
- Crushers (high-starting-torque applications such as mining, food, sugar)
- Compressors and chillers in process industries, where vibration, starting-torque, and power quality are critical.
Jayashree Electron has been a world leader in motor-starting technology since 1978, offering high-capacity soft-starters up to 35 MW / 13.8 kV, built on an advanced manufacturing facility in India.
About the Product – HFSR™ Soft Starter
Pioneered by Jayashree Electron in 1978, HFSR™ (Harmonics Free Series Reactor) soft starters are purely electrical solutions for smooth, efficient motor starting. Designed for motors up to 35 MW / 13.8 kV, they ensure reliability, performance, and energy savings.
Product Features
Pure sinusoidal voltage control eliminates motor stress and harmonics. Smart PLC logic for reactive/active current balancing and power factor correction.
AI-enabled fault detection and predictive diagnostics. IP67 outdoor-rated panels, tested for dust and water ingress. Comprehensive safety: interlocks, sensors, anti-resonance logic, and HMI monitoring.
Solutions:
- Custom-engineered systems from 18 kW / 380 V to 35 MW / 13.8 kV.
- Suitable for synchronous, squirrel cage, and slip-ring motors.
- Integrated start/stop, PF correction, protection, and metering in one panel.
ApplicationS:
- Compressors/Chillers – reduces vibration, torque impact, and extends bearing life.
- Pumps – used in irrigation, cooling, and de-watering systems with smooth ramp-up.
- Fans/Blowers – for steel, power, and process industries; minimizes torque shocks and energy loss.
