In-wheel motor for electric bikes, maximum 1.5 kW, customizable.
WGI Series
A compact and lightweight yet powerful in-wheel motor! We respond to your request for "more power but lighter!" #InWheel #WheelType
The WGI series, short for "Wheel Gear-In," maximizes the features of our coreless motor, particularly its hollow structure, by placing gears within the hollow section, achieving compactness and lightweight design. Additionally, the motor itself is highly efficient, significantly increasing the range! Furthermore, it incorporates EAT (Electrical Automatic Transmission) technology, which enhances torque at low speeds with low current and allows for high-speed rotation in high-speed mode, creating a dream-like new technology that electrifies the transmission. *You can see the details in our demo unit. Please take a look at our new proposal for small mobility. Customization of various shapes, tire types, and outputs is also possible. 【Specifications】 ■ Maximum output: 1,500W ■ Rated voltage: 48Vdc ■ Rated torque: 30Nm ■ Rated speed: 570rpm ■ Outer diameter: φ205 ■ Thickness: 101mm ■ Weight: 1.7kg ■ Gear ratio: 6.5 For more details, please contact us or download the catalog.

basic information
●Compact: Thanks to the built-in gear effect, it is overwhelmingly smaller compared to products from other companies. ●Lightweight: The coreless structure makes it lightweight, contributing to the reduction of the vehicle's weight. ●High Efficiency: Longer battery drive time and increased generation of regenerative energy. ●Cogging-Free: Due to the coreless structure, cogging torque is zero. ●High Torque: By using metal gears instead of resin gears, it achieves three times the torque compared to conventional models. ●High Rigidity: Adopts a through-shaft mechanism, providing good impact resistance against steps and other obstacles. An in-wheel motor is an electric motor that fixes the wheel hub shaft and rotates the motor body. In-wheel motors have many applications, including electric vehicles, electric wheelchairs, and electric assist bicycles. Our in-wheel motor incorporates a gear mechanism inside the motor, achieving overwhelming miniaturization and weight reduction compared to other companies' in-wheel motors.
