FOR IMMEDIATE RELEASE
Softwave Fans Unveils Revolutionary Zero Gravity PMSM™ for Industrial HVLS Fans
Patent Pending Bearing-less Motor Design Eliminates Maintenance, Delivers 100,000-Hour Lifespan with 15-Year Warranty
PUNE, INDIA – Nov 12, 2025 – Softwave Fans Pvt. Ltd., manufacturer of Softwave HVLS Fans, today announced the launch of Zero Gravity PMSM™, a revolutionary motor innovation that fundamentally transforms industrial cooling systems. The patent-pending bearing-less Permanent Magnet Synchronous Motor (PMSM) design eliminates the primary causes of motor failure, delivering zero-maintenance operation with an unprecedented 100,000-hour lifespan backed by a comprehensive 15-year warranty.
"Zero Gravity PMSM™ represents a paradigm shift in industrial motor engineering," said Ganesh Chavan, Founder and CEO of Softwave Fans Pvt. Ltd. "We've eliminated the forces that destroy traditional motors. No bearing currents. No mechanical stress. No maintenance requirements. This breakthrough isn't incremental improvement – this is engineering beyond gravity."
Three Zeros That Change Everything
The Zero Gravity PMSM™ delivers three breakthrough advantages:
ZERO FORCES: The patent-pending bearing-less design eliminates radial bearing forces, the primary cause of premature motor failure in traditional dual-bearing systems. By removing mechanical stress at the molecular level, Zero Gravity PMSM™ achieves lifespans exceeding 100,000 operating hours – equivalent to 27 years of continuous operation.
ZERO MAINTENANCE: Unlike conventional PMSM motors or other motors that require regular bearing replacements, oil changes, gear replacements, and brush servicing, Zero Gravity PMSM™ operates with bearing-less, oil-less, gear-less, and brush-less technology. Facility managers eliminate ongoing maintenance costs, reduce downtime, and free technical staff for value-adding activities.
ZERO SOUND: Operating at whisper-quiet levels below 35 decibels, Zero Gravity PMSM™ creates comfortable work environments, while traditional industrial fans generate noise pollution of 55-70 dB. The optional harmonic-free power delivery ensures silent and efficient operation, improving productivity and worker satisfaction.
Engineering Excellence Meets Economic Reality
Zero Gravity PMSM™ delivers superior performance specifications:
• Lifespan: 100,000+ hours (vs. 1,000-10,000 hours typical failure in harsh industrial conditions)
• Power Factor: 0.97-0.99 with optional harmonic free active front end(vs. 0.6-0.8 conventional)
• Noise Level: <35 dB (vs. 55-70 dB conventional)
• Maintenance Cost: Zero (vs. ₹50,000-₹2,00,000 annually)
• Energy Efficiency: 40-60% reduction in operating costs
• Warranty: 15 years comprehensive coverage
"The total cost of ownership advantage is undeniable," added Chavan. "Our customers eliminate maintenance expenses, reduce energy consumption by up to 60%, and avoid the productivity losses from motor failures. Zero Gravity PMSM™ pays for itself through operational savings, often within 18-24 months."
Made in India for the World
Softwave HVLS Fans featuring Zero Gravity PMSM™ are designed, engineered, and manufactured at Softwave Fans Pvt. Ltd.'s facility in Pune, Maharashtra. The company's commitment to engineering excellence has earned the trust of marquee clients including Danfoss, Saint-Gobain, Brakes India, Arvind Limited, and Bafna Motors, among others.
"We're proving that 'Made in India' means world-class engineering and innovation," said Chavan. "Our vision is to establish Softwave as the global leader in HVLS fan technology, and Zero Gravity PMSM™ is the foundation for achieving that ambition."
Comprehensive Product Range
Zero Gravity PMSM™ powers the complete Softwave platform, spanning three generations across sizes ranging from 8 feet to 30 feet in diameter. The fans integrate seamlessly with Building Management Systems (BMS) through Modbus connectivity, enabling smart facilities management and predictive environmental control.

TECHNICAL BACKGROUNDER
The Science Behind Zero Gravity PMSM™
The Problem with Traditional Motors:
Conventional PMSM motors employ dual-bearing configurations that are susceptible to PWM inverter-induced bearing currents, resulting in capacitive discharge voltages that lead to electro-erosion. These high-frequency currents damage bearing surfaces, leading to premature failures at 1,000-10,000 hours, despite rated capacities of 100,000 hours or more.
The Zero Gravity Solution:
By employing a revolutionary bearing-less design, Zero Gravity PMSM™ eliminates radial bearing forces entirely. The innovative architecture redistributes mechanical loads, removing stress concentrations that accelerate wear. Combined with advanced stator winding configurations that minimize common-mode voltage, the system operates in a near-frictionless state – metaphorically achieving "zero gravity" conditions for the rotating assembly.
Key Innovations:
1. Bearing-less Architecture: Patent-pending mechanical design eliminates dual-bearing stress
2. Force-Free Operation: Zero radial bearing forces during operation
3. Advanced Winding Design: Minimizes common-mode voltage and bearing currents
4. Optional Harmonic-Free Power: Clean sinusoidal power delivery without distortion
5. Thermal Management: Optimized heat dissipation extends component life
Competitive Advantages
vs. Big Ass Fans: Zero Gravity PMSM™ operates at <35dB vs. Big Ass Fans' louder operation, while delivering superior power factor and efficiency.
vs. Hunter Fan: Zero Gravity PMSM™'s bearing-less design eliminates the bearing current problems inherent in Hunter's dual-bearing configuration.
vs. MacroAir: Zero Gravity PMSM™ delivers 10x longer lifespan with zero maintenance, compared to MacroAir's traditional maintenance schedules and shorter motor life.
Environmental Impact
Zero Gravity PMSM™ supports sustainability goals:
• Energy Reduction: 40-60% lower power consumption vs. traditional cooling
• Material Conservation: 100,000-hour lifespan reduces replacement frequency
• Zero Waste: Eliminates disposal of oils, lubricants, worn bearings, and gears
• Reduced Carbon Footprint: Lower energy consumption and longer product life minimize environmental impact
