Electric rear-wheel hub motor: the core power for driving heavy loads and urban commuting
As a key driving system for electric bicycles, freight vehicles and urban commuter vehicles, electric rear-wheel hub motors have developed rapidly in recent years under the trend of smart travel and green transportation. Compared with mid-mounted motors or front-wheel drive systems, rear-wheel hub motors have the advantages of direct torque output, efficient transmission, simple wiring, and controllable costs. They are especially suitable for urban road conditions with ramp climbing, heavy-load transportation, and frequent start-stop.

The rear-wheel hub motor has efficient power transmission, good climbing ability, strong structural stability, and convenient installation and maintenance. The power output of the rear-wheel hub motor directly acts on the vehicle drive wheel, eliminating intermediate links such as chains and drive shafts, reducing power transmission, and improving the utilization rate of lost energy. The rear wheel usually carries a larger proportion of the vehicle's load, so arranging the motor at the rear wheel can better play its power advantage. Most rear-wheel motors are designed with complex terrain and heavy-load transportation needs in mind, and often have greater peak torque. The rear wheel is not only the load center, but also the drive wheel. This arrangement is conducive to exerting stronger power during climbing or starting, and reducing the risk of slipping.

The rear wheel hub motor is easier to integrate with the multi-speed system in structure, and has higher system integration and flexibility. When used with the transmission, the vehicle can obtain the most suitable torque/speed output under different slopes and road conditions. The modular integrated structure of the rear wheel hub motor is convenient for batch assembly and post-service. Most motors are directly integrated with the rear wheel axle group. The standard opening design can quickly adapt to the mainstream frame. The wiring logic between the motor and the controller and battery is simple, supporting fast plug-in and maintenance.

Since its establishment in 1995, Ningbo Yinzhou HENTACH Electromechanical Co., Ltd. has been deeply engaged in the field of motor manufacturing and aluminum-magnesium alloy casting, forming an integrated manufacturing system covering micro DC motors, electric vehicle hub motors and their core components. The company has launched multiple models in the field of electric rear wheel hub motors to meet multiple scenarios from urban commuting to high-load transportation. The company has produced E-Type series rear wheel hub motor products including E-Type RC750-2, E-Type RF500-1, and E-Type Pro RF750. The E-Type RC750-2 is suitable for E-Cargo and E-MTB, with a rated power of 750W, a peak torque of 85Nm, a 142mm gear opening, and supports 8-10-speed cassette flywheels, compatible with complex terrain and heavy load requirements. The E-Type RF500-1 is a medium-power motor, suitable for 20-28-inch wheels and 36/48V systems, with 75Nm torque and 5.4 reduction ratio, which helps to accelerate smoothly at low speeds. The E-Type Pro RF750 has 750W power and 85Nm torque, a 135mm gear opening, and is suitable for 7-speed threaded flywheels to enhance climbing and freight performance. Ningbo Yinzhou HENTACH Electromechanical Co., Ltd. also produces rear hub motor products of multiple models such as S-Type R2000 Thru Axle, C-Type R350, and D-Type Thru Axle. The S-Type R2000 Thru Axle is designed for E-Fat, Moped, and heavy-duty models. It adopts a 190mm wide gear opening and a 12mm straight-through shaft structure, supporting up to 2000W power and more than 170Nm peak torque. The HENTACH patented plastic-steel gear system effectively avoids the wear problem of traditional nylon teeth in high-torque scenarios. The C-Type R350 is aimed at urban riding, with 250-400W power and 45Nm torque, supports 7-speed threaded flywheels, and IP65 protection level to ensure daily commuting stability and weather resistance. The D-Type Thru Axle is designed for lightweight e-MTB and Gravel models, with a 2.4kg motor (including flywheel), a 148mm straight-through shaft structure, 250W power and 50Nm peak torque, supports torque sensors, and provides smooth power response.

HENTACH's products combine patented plastic-steel composite gear technology, which is 5 times stronger than traditional nylon gears, adapting to high-power/high-torque scenarios and significantly extending the life of the motor. HENTACH has full-process manufacturing capabilities. The factory covers an area of ​​over 9,000 square meters and has more than 60 die-casting and CNC precision processing equipment. It has a complete industrial chain from parts to complete machine assembly. It also has a reliable quality control system, and its products have passed ISO9001 certification, providing comprehensive guarantee for product quality.
