Description

Technical Field

[0001] This utility model belongs to the field of mechanical and electrical technology, specifically, it relates to a motor assembly. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] The motor is the heart of a drone, and it comes in two types: brushed motors and brushless motors. Brushed motors use mechanical commutation and typically contain carbon brushes; while brushless motors use electronic commutation, employing Hall effect sensors to sense the position of permanent magnets to control the current direction. Brushless motors are more common in drones because of their high drive efficiency and ease of maintenance. When selecting a motor, you need to consider parameters such as size, kV value, number of slots, number of poles, and torque (T). These parameters all affect the motor's performance and applicable scenarios.

[0004] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a current-carrying coil, which acts on the rotor to create magnetoelectric torque. Electric motors are classified into DC motors and AC motors based on the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous. An electric motor mainly consists of a stator and a rotor. The direction of the force exerted on a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0005] 1. The existing equipment does not have the function of heat dissipation. When the internal temperature of the motor is too high, the motor load becomes too large, which affects the service life of the motor and the working effect.

[0006] 2. Existing equipment involves cumbersome disassembly and assembly procedures when replacing and repairing motors. This process can damage internal parts of the motor, thereby reducing the efficiency of maintenance personnel. Utility Model Content
