The invention discloses an improved electric vertical take-off and landing aircraft motor heat dissipation air inlet channel structure which comprises an NACA air inlet channel, the NACA air inlet channel is formed in a motor arm, a lip is arranged on the NACA air inlet channel, a motor heat dissipation air inlet is formed in the end of the motor arm, the motor heat dissipation air inlet is communicated with the NACA air inlet channel, the end of the motor arm is connected with a motor, and the motor heat dissipation air inlet is communicated with the NACA air inlet channel. The motor heat dissipation air inlet faces the motor, the NACA air inlet channel is a divergent channel, the width of an airflow initial inlet of the NACA air inlet channel is set as W1, the width of a lip is set as W2, the depth and the length of the NACA air inlet channel are set as H and L respectively, W2/H is controlled to be 3-5, and L is not smaller than two times of W2. The NACA air inlet channel in the structure can improve heat dissipation of the motor, safe and reliable operation of the motor is ensured, and the voyage of the electric aircraft is improved due to low aerodynamic resistance.
