Sensorless BLDC Fan for Railway Carriage (400mm sweep)
RDSO / Spec No.
TL/0021-2005 (Rev3)
Application
Indian Railways (Rolling Stock) - Railway Carriage Ventilation & Passenger Comfort
Product Specifications & Details
The Sensorless BLDC Fan for Railway Carriage (400mm sweep) manufactured by General Auto Electric Corporation (GAEC) provides energy-efficient air circulation across passenger coaches[cite: 15]. Compliant with RDSO Specification No. TL/0021-2005 (Rev3), this fan features a microcontroller-based driver for precise speed control, maintaining constant fan speed across wide input voltage variations (90 to 140V DC)[cite: 15]. Built with unbreakable FRP blades, a modular housing design, sealed bearings, and comprehensive electrical protection features, it ensures quiet and low-maintenance operation in railway environments[cite: 15].
Key System Features
- Sensorless BLDC Technology: Microcontroller-based driver ensures energy efficiency and low power consumption (<32W)[cite: 15].
- Constant Air Flow: Delivers high air delivery (>60m³/min) with constant speed across varying input voltages[cite: 15].
- Durable & Low Maintenance: Modular construction with unbreakable FRP blades and maintenance-free sealed bearings[cite: 15].
- Comprehensive Electrical Protection: Built-in reverse polarity, reverse direction, locked rotor, over-voltage, and under-voltage protection[cite: 15].
- Quiet Operation: Low noise performance (< 55dB) designed for optimal passenger comfort[cite: 15].
- RDSO Approved: Fully certified and approved by RDSO / IRO for railway carriage deployment[cite: 15].
