Tips: Key technical issues in the research of hub motor systems

• The electric hub motor system integrates multiple functions such as driving, braking, and bearing, making it difficult to optimize the design.
• The internal space of the wheel is limited, which requires high power density and performance of the wheel hub motor, and the design is difficult.
• The integration of the hub motor and the wheel results in a large unsprung mass, which deteriorates the suspension vibration isolation performance, and affects the vehicle's handling and safety under uneven road conditions. At the same time, the ebike hub motor will bear a large impact load on the road surface, and the motor has strict requirements for vibration resistance.
• The problem of overheating and burning of the in wheel motor caused by insufficient cooling is likely to occur when the vehicle is under heavy load and low speed climbing long slopes. The heat dissipation and forced cooling of hub motors need to be paid attention to.
• The wheels are easy to collect water and dirt, which will cause corrosion and destruction of the in-wheel motor, and affect the reliability of the life.
• The fluctuation of the operating torque of the wheel hub motor may cause vibration and noise of the automobile tire, suspension and steering system, as well as other vehicle sound and vibration problems.
