It is the invention of a high-speed BLDC ceiling fan compatible with the existing systems and the market. This patent represents the fundamental innovation that led to the First super energy-efficient ceiling fan in India.

Typically, BLDC motors have hall effect sensors to detect the position of the rotor and enable smooth control of the motor. Superfan devised a unique algorithm that enabled position detection solely through firmware. This innovation was critical for the industry in improving reliability and lowering the cost of a BLDC ceiling fan.

Superfan developed a firmware that compensated for the variation in the back emf, thereby eliminating the need to precisely magnetize the permanent magnets. This innovation reduced the manufacturing time by more than 100%.

BLDC ceiling fans by design are more suited to be controlled by a remote. Consumers prefer capacitive type wall regulators in some scenarios. Superfan is creating the first regulator-controlled BLDC ceiling fan.

The feature enables the speed of the fan to be controlled by toggling the ON/OFF switch.

Aesthetics is one aspect of the ceiling fan; typical ceiling fans with decorative additions on the blades affect performance and productivity. Superfan utilized cross-functional technology in ceiling fans to enhance aesthetics without affecting performance and productivity.

Superfan consistently demonstrates its position as a technology leader by exceeding the standards set by others and its own.

Typically, the BLDC motor requires adhesives to keep the magnet assembly in its place, which has a 24-hour curing time. The new method to fix the magnets without adhesive can eliminate the curing process and the manufacturing process of gluing.

In BLDC motors, the magnets are in the internal rotor. The rotor is outside of the motor in ceiling fans. Superfan constructed an outer rotor BLDC motor that is compatible with the existing fan design.

Superfan developed the world's most efficient BLDC motor in 2012, which reduced the power consumption of the ceiling fan by more than 50%. The other integral part of a fan is its blades. Superfan developed a cost-effective ceiling fan blade that increased the efficiency further by 30%. This first model that utilized this design became the most efficient ceiling fan in India in 2021.

This invention is a Speed control system and method that enable a BLDC motor–based fan to operate with a traditional wall-mounted regulator by translating the regulator’s input into appropriate control signals for the BLDC motor controller. The invention ensures smooth and precise speed control, maintains compatibility with existing electrical wiring and improves energy efficiency,

This invention focuses on a unified control system that manages the operation of a fan along with one or more electrical appliances from a single control platform. This invention enhances user convenience, optimizes energy usage, and supports flexible operation through manual or automated commands.

This invention is about the high efficiency ceiling fan blades and its variable forms of sizes that could match in different room spaces from a small room to a big hall as the fan blades are designed from a small size of 24 inch to 60 inch sweep without compromising on its performance and high energy efficiency.

This invention enables the fan to receive customized voice commands through wireless communication, allowing hands-free control of functions such as ON/OFF and speed regulation without reliance on external hubs or internet connectivity, thereby improving user convenience, reliability, and accessibility.
