"Why Is Weak Magnetic Control Necessary For High-Speed Motors?"
📊Permanent magnet synchronous motor is the core driving device of new energy vehicle power plants in China. It is well known that at low speeds, permanent magnet synchronous motor adopts maximum torque current ratio control, which means that given a torque, the minimum synthesized current is used to achieve it, thereby minimizing copper loss.

📊So at high speeds, we cannot use MTPA curves for control, we need to use MTPV, which is the maximum torque voltage ratio, for control. That is to say, at a certain speed, make the motor output the maximum torque. According to the concept of actual control, given a torque, the maximum speed can be achieved by adjusting iq and id. So where is the voltage reflected? Because this is the maximum speed, the voltage limit circle is fixed. Only by finding the maximum power point on this limit circle can the maximum torque point be found, which is different from MTPA.

"Advantages, Difficulties, and New Developments of Axial Flux Motors"
🆕Compared to radial flux motors, axial flux motors have many advantages in electric vehicle design. For example, axial flux motors can change the design of the powertrain by moving the motor from the axle to the inside of the wheels.

🆕Axial flux motors are receiving increasing attention (gain traction). For many years, this type of motor has been used in stationary applications such as elevators and agricultural machinery, but over the past decade, many developers have been working to improve this technology and apply it to electric motorcycles, airport pods, cargo trucks, electric vehicles, and even airplanes.

🆕Traditional radial flux motors use permanent magnets or induction motors, which have made significant progress in optimizing weight and cost. However, they face many difficulties in continuing to develop. Axial flux, a completely different type of motor, may be a good alternative.

"Hollow technology of motor shaft"
The motor shaft is hollow, with good heat dissipation performance and can promote lightweight of the motor. Previously, motor shafts were mostly solid, but due to the use of motor shafts, the stress was often concentrated on the surface of the shaft, and the stress on the core was relatively small. According to the bending and torsional properties of material mechanics, the internal part of the motor shaft was appropriately hollowed out, and only a small outer diameter was needed to increase the external part. The hollow shaft can meet the same performance and function as the solid shaft, but its weight can be significantly reduced.

Meanwhile, due to the hollowing of the motor shaft, cooling oil can enter the interior of the motor shaft, increasing the heat dissipation area and improving the heat dissipation efficiency. Under the current trend of 800V high-voltage fast charging, the advantage of hollow motor shafts is greater. The current production methods for hollow motor shafts mainly include solid shaft hollowing, welding, and integrated forming, among which welding and integrated forming are widely used in production.
