From design to mass production: the technical advantages and quality assurance of the E-Scooter Hub Motor
The wheel hub motor is a power system that directly integrates the drive motor with the wheel structure. Compared with the traditional motor system, it omits the intermediate transmission mechanism and directly converts electrical energy into the kinetic energy of the wheel, which is more efficient and simpler in structure. The wheel hub motor embeds the motor inside the wheel, without the need to set up a complex mechanical transmission system, which greatly saves vehicle space and weight. It is especially suitable for electric scooters, electric bicycles and folding electric vehicles that have high requirements for space and vehicle quality control. Since the wheel hub motor directly drives the tire, there is no mechanical loss and delay, and its energy efficiency ratio is higher than that of the traditional transmission system. The driver can clearly feel a more sensitive and linear power response when starting, accelerating or braking. The wheel hub motor has no chain or gear transmission structure, which avoids the mechanical noise generated by metal friction. At the same time, modern high-quality wheel hub motors are often equipped with optimized windings, noise-reducing magnetic steel structures and silent bearings, making the entire vehicle almost silent when running, which is very suitable for scenes with high requirements for environmental noise such as cities, campuses, and parks. In addition, the wheel hub motor adopts a fully enclosed structure design, and the internal components are maintenance-free, which greatly reduces the failure rate and use cost. The wheel hub motor has a compact structure, saves space, has high transmission efficiency, quick response, low noise, and low maintenance cost. It is very suitable for electric scooters to improve the performance of electric scooters.

Although the electric scooter hub motor is small in size, it involves high-precision motor manufacturing and lightweight material processing, which requires very high requirements. The core difficulties include magnetic steel arrangement and magnetic circuit design, which directly affect the motor efficiency and temperature rise; stator winding process, winding consistency and insulation heat resistance are the key to the life of the motor; gear accuracy and lubrication treatment of the reduction system determine the operation stability and quiet effect; high-strength shell die-casting and heat dissipation design to prevent long-term operation thermal decay.

Ningbo Yinzhou HENTACH Electromechanical Co., Ltd. has accumulated rich design, manufacturing and testing experience in the field of electric scooter wheel hub motors and has integrated manufacturing capabilities. HENTACH has a 9,000 square meter production base and a 5,000 square meter building area, equipped with more than 60 internal core production equipment, including 500-ton die-casting machines, high-precision CNC machining centers, laser marking equipment, micro-arc oxidation equipment, two sets of electric vehicle motor test platforms and other professional equipment. The company can achieve internal control of the entire process from aluminum-magnesium alloy die-casting to motor assembly and testing to ensure product consistency and high quality. In addition, HENTACH implements ISO quality system standards from raw materials, processing, assembly, testing to packaging to ensure that each motor meets the requirements of high stability and high safety, and adopts high-performance rare earth magnets and patented nylon steel composite gear structures to improve quietness and wear resistance. Nylon teeth can reduce vibration and noise, while steel teeth can enhance strength and load-bearing capacity. HENTACH will continue to focus on "high quality, innovation and reliability" to help customers create a series of high-performance and high-durability electric scooter hub motor products.
