Below are general answers on typical components of brushed motor drones from the list of GAO Tek’s brushed motor drones 

 

Electronic Components 

  • Brushed Motors: Brushed motors are the primary propulsion mechanism in these drones. They consist of an armature (rotating coil), a commutator, brushes, and a permanent magnet. The brushes make physical contact with the commutator, supplying current to the motor windings. This interaction generates a magnetic field, causing the armature to rotate and produce thrust. Brushed motors are less efficient than brushless ones but are cost-effective and easy to replace 
  • Electronic Speed Controllers (ESCs): The ESCs regulate the speed, direction, and braking of the brushed motors. In drones with brushed motors, these controllers are typically integrated into a single board or directly on the flight controller. The ESC interprets signals from the flight controller and adjusts the power supplied to each motor to control the drone’s movements. 
  • Flight Controller: The flight controller is the brain of the drone, responsible for stabilizing flight, processing input commands, and managing all aspects of drone behavior. It includes sensors like gyroscopes and accelerometers to detect orientation and movement. In GAO Tek’s brushed motor drones, the flight controller may also house the ESCs, further simplifying the electronics. 
  • Battery: The battery powers all electronic components, including the motors and flight controller. Lithium polymer (LiPo) batteries are commonly used due to their high energy density and lightweight nature. Proper battery selection is crucial as it directly impacts flight time and performance. 
  • Radio Receiver: This component receives control signals from the remote transmitter operated by the pilot. The receiver decodes these signals and relays them to the flight controller, enabling real-time control of the drone’s movement and functions. 

Software Components 

  • Flight Control Firmware: The flight controller operates on firmware, which is specialized software that governs the drone’s flight characteristics, stability, and responsiveness. This firmware interprets sensor data and input commands, adjusting motor speeds to maintain desired flight conditions. Popular firmware for drones includes Betaflight, Cleanflight, and iNav. 
  • Remote Control Software: Software on the pilot’s remote controller (or accompanying app) allows for configuration, calibration, and control of the drone. Advanced features may include custom flight modes, fail-safe settings, and telemetry data display. This software is crucial for fine-tuning the drone’s behavior to suit different flying conditions. 
  • Mobile Apps (Optional): Some GAO Tek’s brushed motor drones can be paired with mobile apps that provide additional functionality such as live video streaming (FPV), GPS tracking, or mission planning. These apps often allow for firmware updates, diagnostics, and parameter adjustments, enhancing the drone’s versatility. 

Mechanical Components 

  • Frame: The frame provides the structural foundation for the drone, housing all electronic components and ensuring rigidity during flight. Common materials include plastic, carbon fiber, and aluminum. In GAO Tek’s brushed motor drones, the frame is often lightweight and designed for easy assembly and repair. 
  • Propellers: Propellers convert the rotational motion of the motors into thrust, enabling the drone to lift off and maneuver. The size, pitch, and material of the propellers are carefully chosen to match the power output of the brushed motors and the desired flight characteristics. Plastic propellers are typical for their balance between durability and cost. 
  • Landing Gear: Landing gear protects the drone’s electronics and motors during takeoff and landing. In smaller GAO Tek’s brushed motor drones, this may simply be integrated extensions of the frame, while larger models might have dedicated legs or pads. 
  • Motor Mounts: Motor mounts secure the brushed motors to the drone’s frame and absorb vibrations during flight. Proper alignment and secure attachment of the motors are vital to prevent imbalances that could affect flight stability. 
  • Camera (Optional): Some brushed motor drones include a camera for capturing aerial footage or providing a first-person view (FPV) to the pilot. The camera may be fixed or mounted on a gimbal for stabilization. While not as common in entry-level models, higher-end brushed drones can feature basic cameras.
