Motor BeastFPV S2812 900KV

Order the BeastFPV S2812 900KV motor for your drone - choose the power for long flights!

BeastFPV S2812 900KV motor for drone is a specialized engine for smooth and long flights. Its design is optimized to handle large screws and high voltages. You'll get an efficient propulsion system for long-range missions and aerial photography. This engine produces impressive torque at relatively low revs. It will become the heart of your rugged and reliable aircraft.

This model stands out for its low KV value (900 rpm per volt). This means that it unlocks the potential of batteries with a large number of S. The engine works effectively with propellers of large diameter and pitch. Your drone will be able to lift a payload and stay in the air for a long time. This is the choice of pilots for whom range is important, not just speed.

• Low KV (900) for efficient operation at high voltage.

• High torque for smooth control of large propellers.

• High quality build and balancing from the BeastFPV brand.

• Optimal cooling due to the thoughtful design of the stator.

• Long service life thanks to reliable bearings and materials.

How does a low KV motor work?

This brushless motor converts electrical energy into mechanical energy. It receives three-phase current from the regulator. The stator magnetic field interacts with the rotor magnets. This causes the shaft and propeller to rotate. A low KV value means more turns of thin wire in the stator. This engine develops maximum torque at low speeds.

It is torque, not maximum speed, that is important for large propellers. They create more thrust at lower rotation speeds. This reduces overall system power consumption. Your battery will use its charge more economically. You'll get more minutes of flight from the same battery weight.

Technical characteristics and scope of application

Model S2812 has a stator with a diameter of 28 mm and a height of 12 mm. The operating voltage is usually 4-6S, sometimes up to 8S. The recommended power reaches several hundred watts. The motor uses quality bearings for minimal friction. The shaft is made of durable steel for a secure propeller fit.

This motor is not designed for high speed racing in small formats. His element is cruising flights over long distances. It is ideal for heavy 7-10 inch freestyle drones. It is also in demand in filming platforms and mapping copters. The correct selection of a propeller-battery pair will reveal its full potential.

An appropriate speed controller is required for efficient operation. It must maintain high voltage and provide a smooth start. It is recommended to use propellers with a diameter of 7 to 10 inches. Low pitch props are best for maximum thrust. It is important to prevent the motor from overheating during prolonged operation on the ground.

The motor installation is standard for most frames. It is attached to the quadcopter arm using screws. Three power wires are soldered to the speed controllers. The direction of rotation can be easily changed by rearranging any two wires. After installation, software calibration is required in the flight controller settings.
