Fans & Air Movement – BLDC Fan Motors & Controllers

Overview

Application segment for OEMs designing fan and air-movement products that require efficient, reliable motor–controller solutions. Versa Drives supplies electronically commutated (ECM) fan motors and controllers based on BLDC / PMSM technology for ceiling fans, TPW (table–pedestal–wall) fans, exhaust fans, air coolers, air circulators and ventilators.

Our BLDC ceiling fan platform powers Superfan®, one of India’s most efficient ceiling fan ranges, with more than a decade of field operation. The same core motor–drive technology is available as OEM-ready motors and controllers that can be adapted to your mechanical design, airflow targets and control features.

Fan system capabilities

Fan and motor types

• Ceiling fans – 1200 / 1400 mm and other sweep sizes
• TPW fans – table, pedestal and wall fans
• Large-diameter exhaust and ventilation fans
• Air coolers and air circulator fans
• Small blower / ventilator applications in appliances and HVAC
• All solutions are based on electronically commutated motors (ECM) – primarily BLDC / PMSM; SRM-type options can be explored under custom OEM programmes

Power and supply ranges

• Typical fan input power range: ~20 W to 1.5 kW, depending on application
• Supply options: 230 Vac, 50 Hz single-phase mains input; selected low-voltage DC variants where required
• Control architectures: sensorless FOC and other advanced control schemes for BLDC / PMSM ECMs

Control, interfaces and features

• Multi-step or quasi-continuous speed control with profiles tuned for comfort, airflow and noise
• Interfaces for wall regulators, IR/RF remotes, MCU/UART/PWM and smart-home gateways (variant dependent)
• Options for direction control, oscillation control (TPW), timer functions and soft start
• Communication interfaces (e.g. UART / MODBUS) for integration into larger systems where applicable

Protection, standards and reliability

• Built-in protections: under/over-voltage, overcurrent, overload, locked rotor, over-temperature (fan and drive dependent)
• Designs aligned with relevant IEC and EMC requirements for appliance and HVAC equipment
• Platforms validated in harsh Indian operating conditions via Superfan® ceiling fans and other field deployments

Applications & fan categories

• Residential and commercial BLDC ceiling fans targeting high efficiency and regulatory labels
• Table, pedestal and wall fans for homes, offices and commercial spaces
• Large exhaust fans for poultry sheds, greenhouses, warehouses and industrial buildings
• Air coolers and air circulator fans in home and commercial appliances
• Ventilation and small HVAC blowers in equipment cabinets, air purifiers and specialised ventilators
