Order the Freerchobby 154120 engine - absolute power for industrial giants

The Freerchobby 154120 engine is a powerplant that sets new standards in power. It is designed for ultra-heavy unmanned platforms and industrial solutions. This motor provides unprecedented thrust for lifting maximum loads. You will be able to implement the most ambitious projects in commercial aviation. This is the pinnacle of engineering for the professional drone sector.

Key advantages of the motor

• The colossal stator size is 154×120 mm. Provides maximum torque in its class.

• Ultra-low KV for extreme traction. Optimal for giant propellers.

• Special reinforced housing and shaft design. Designed for repeated cycles of maximum load.

• High voltage design for efficient power transmission. Works with 48V and higher systems.

• Top quality components and balancing. Guarantees smooth operation and long service life.

The essence of the work and design

This is an industrial scale brushless external rotation motor. His work is based on the fundamental laws of electromagnetism. Powerful three-phase current from the controller is supplied to the stator windings. The created magnetic field interacts with the field of the rotor magnets. This results in the generation of enormous torque at low revs. The massive stator allows the use of windings with a large wire cross-section.

Technical characteristics and scope of application

The Freerchobby 154120 engine is a top-tier powerplant. Its KV value is extremely low, often in the range of 50-100 rpm per volt. The operating voltage is intended for high-voltage systems ranging from 48V (12S+) and above. Power consumption can reach tens of kilowatts at full load. It is designed to produce thrust measured in the hundreds of kilogram-forces.

This motor is designed to operate propellers with a diameter of 40 to 50 inches or larger. It is the basis for heavy cargo multicopters for logistics purposes. It is used in the largest agricultural spray drones. It is in demand in specialized aircraft platforms for firefighting. It is also used in research and rescue complexes for special purposes.

Control requires specialized industrial ESC controllers. Often these are custom solutions designed for high current and voltage. Integration of such a motor requires custom design of the entire platform. A heavy-duty titanium or aluminum frame and unique motor mounts are required. All connections and fasteners must be suitable for extreme loads.

Service is carried out according to strict regulations of service centers. Regular monitoring of temperature, vibration and bearing condition is mandatory. Working with such an engine means designing a turnkey system. Accurate calculation of all components is important: from the propeller to the control system.
