Integrated motor wheel: a key component to promote the innovation of light electric vehicle power system
The integrated motor wheel is a power module that highly integrates key components such as motor, wheel hub, reduction device, and even control system in a compact structure. It eliminates the intermediate transmission structures such as chains, belts, gearboxes, etc. commonly seen in traditional electric systems, and directly embeds the motor into the wheel or near the wheel axis, realizing the complete integration of the drive system and the wheel. Traditional electric drive systems require the installation of multiple scattered components, with complex wiring and occupying a lot of space. The integrated motor wheel concentrates all core drive modules inside or near the wheel hub, greatly saving the space of the whole vehicle, facilitating lightweight and modular vehicle design, and is particularly suitable for folding electric vehicles and small scooters with high requirements for compact structure. In addition, due to the presence of chains or belts, the traditional transmission structure will have obvious energy loss and hysteresis response. The integrated motor wheel adopts a direct drive mode, which can convert electrical energy into kinetic energy almost losslessly, and the system transmission efficiency is as high as more than 90%. The integrated motor wheel eliminates the mechanical transmission link, and the power response is more linear and direct. Drivers can get a sensitive and smooth power experience when starting, accelerating, and braking, which is especially important in user experience-oriented products such as shared scooters and smart two-wheelers. The use of high-precision gear sets and optimized magnetic circuit structures significantly reduces the mechanical friction generated during the operation of the motor, effectively reducing noise and vibration, and is extremely friendly to nighttime use, campuses, communities and other quiet places. Due to the integrated structure, no chain and no gearbox, there is almost no need for regular maintenance.

HENTACH has launched Integrated Motor Wheel products in multiple sizes to meet the needs of different models. The 12-inch motor wheel has a rated voltage of 36-52V, a rated power range of 250-350W, a peak torque of 45 N.m, and weighs 3.3kg. It is suitable for lightweight electric scooters and urban commuter folding electric vehicles. The 16-inch motor wheel also has a rated voltage of 36-52V, a rated power range of 250-400W, a peak torque of 55 N.m, and weighs 4kg. It is suitable for urban electric bicycles and medium-speed commuter vehicles. The rated voltage of the 20-inch motor wheel is the same as the previous two products of the same series, with a rated power range of 250-350W, a peak torque of 60 N.m, and a weight of 4.8kg. It is suitable for long-range electric bicycles and travel vehicles. The rated power of the 20-inch S-type high-power motor wheel is increased to 750W, the peak torque is as high as 95 N.m, and the weight is 7.5kg. It is suitable for tricycles and freight-type light electric vehicles with high climbing ability requirements or large loads.

HENTACH integrated motor wheel uses a patented nylon-steel composite reduction gear, which takes into account both strength and quietness. Nylon gears effectively absorb operating vibrations and reduce noise; the steel tooth part improves the overall bearing strength and durability. All use high coercive force rare earth permanent magnets, which effectively improve the motor efficiency and anti-demagnetization ability, so that the motor is still stable and reliable under high load and long-term operation. Combined with many years of motor design experience, the magnetic circuit structure and coil layout are optimized to effectively reduce temperature rise, increase torque output, and extend service life. The protection level of the whole machine can reach IP54~IP65, which can adapt to a variety of harsh outdoor environments.
