This document discusses BLDC ceiling fans produced by Digital Solar. It summarizes that Digital Solar pioneered BLDC solar ceiling fans in India, using a BLDC motor that improves reliability over traditional motors. The BLDC motor requires electronic management via a microcontroller to precisely time energizing coils for accurate speed and torque control. Digital Solar focuses on high quality components like CRNO steel, specific grade copper wire, and hard ferrite magnets to ensure the consistent power and performance of their BLDC ceiling fans.

BLDC Motor does away with the mechanical commutator used in
traditional motors, replacing it with an electronic device that improves
the reliability and durability of the unit.
BLDC Motor can be made smaller and lighter than a brush type with the
same power output.
A BLDC motor is known as a “synchronous” type because the magnetic
field generated by the stator and the rotor revolve at the same frequency.
WHAT IS A BLDC MOTOR ???
field generated by the stator and the rotor revolve at the same frequency.
One benefit of this arrangement is that BLDC motors do not experience
the “slip” typical of induction motors.
But…
BLDC Motor has a downside, the motors do need electronic management
to run. For example, a microcontroller – using input from
sensors indicating the position of the rotor – is needed to
energize the stator coils at the correct moment. Precise
timing allows for accurate speed and torque control, as
well as ensuring the motor runs at peak efficiency

KEY TO SUCCESS OF BLDC MOTOR…
Our research clearly shows the BLDC Motor is more successful
through quality of its Components
1. Stamping - Material used for Stamping (we use CRNO Sheet
these sheets are basically used in manufacturing of
transformers because the wattage looses are lower)
And these are as follows:
transformers because the wattage looses are lower)
2. Wire for Winding – Only Specific Grade Copper Wire is used
(better performance)
3. Magnets - We use Hard Ferrite Magnet (Consistent power)
4. Drive - The synchronization of Stator and Rotor is achieved by
the Drive which is designed in house (High Quality
Components)
5. Winding - How the winding is done (automated)
6. Body - Our fan body is Aluminum (better Durability &
Reliability)
