Currently, axial motors are widely used in new energy vehicles, aerospace, ship propulsion, robots, wind power generation, and other occasions that require high torque density and compact space.
The small size and low theoretical cost of axial flux motors are expected to solve the cost and volume problems of wheel-side motors and promote the large-scale application of wheel-side motors. The power density advantage of axial flux motors can output sufficient torque while maintaining lightweight and reducing unsprung mass, promoting the mass application of hub motors.
In 2021, the "Spirit of Innovation" in the ACCEL project came out, setting a pure electric aircraft airspeed record of 345.4 miles per hour. The axial motor carried by this fixed-wing aircraft has a propulsion power of 400KW.
It is estimated that the aircraft motor market will grow from US$8.2 billion in 2022 to US$12.9 billion in 2027, with a compound annual growth rate of 9.4%. Among them, axial motors with a power density of 5-10kW/kg will occupy the largest market share during the forecast period.
Axial motors have significant advantages in improving ship efficiency, reducing emissions, and optimizing structures. The naturally high torque density means higher power conversion efficiency and a more compact structural design than traditional motors, which is crucial for optimizing ship propulsion systems and saving energy and reducing consumption.
It is estimated that the electric ship market will reach US$11.43 billion in 2028, growing at a compound annual growth rate of 12.65% between 23 and 28 years.
High-end robots have the following requirements for joint drive motors: rapidity. The time from the motor obtaining the command signal to the completion of the working state required by the command should be short; the starting torque-to-inertia ratio is large. In the case of driving loads, the robot joint motor is required to have a large starting torque and a small moment of inertia; small size, small mass, and short axial size; it can withstand harsh operating conditions, can perform very frequent forward and reverse and acceleration and deceleration operations, and can withstand overload in a short time.
The performance requirements that radial motors cannot achieve, such as providing high peak torque and high response speed, high-power thrust at the premise of millimeter-level thickness, precisely hit the advantage range of axial motors.
According to statistics, the market value of mobile robot parts is expected to grow at a high CAGR of 44.8% starting from 2022, reaching US$7.4 billion in 2027.
