Tesla Model 3 and model y recently began to deliver models equipped with domestic motors. Compared with the new cars previously delivered, the motor power and torque of the new models have been improved. Compared with before, Tesla's domestic motor adopts flat wire technology.

Benefiting from the performance advantages of domestic motors, the power and torque of Tesla Model 3 and model y increased slightly. Theoretically, flat wire motor has the performance advantages of high motor efficiency, increased full slot rate, increased power density, good heat dissipation, low noise, lightweight and so on. Model 3 and model y models of domestic motor version only replace the rear motor. After model 3, the maximum power of the motor is increased from 202kw to 220kw, and the maximum torque is increased from 404nm to 440nm; After model y, the maximum power of the motor is increased from 180kW to 220kw, and the maximum torque is increased from 326nm to 440nm. Although there is little difference in user experience, it proves the performance advantage of flat wire motor.
