QS MOTOR QS138 3000W 70H V2 Mid Drive Motor Powerful 72V Peak-power 10000W Electric Motorcycle Center Motor

Advantages

* Power and Efficiency: Rated power reaches 3000W, with even higher peak power, such as 10,000W, as indicated in some specifications. Utilizing permanent magnet synchronous technology and a V-shaped rotor design, the motor achieves a maximum efficiency of ≥94%, effectively improving the conversion of electrical energy into mechanical energy and reducing energy loss.

* Speed and Power Output: The base speed is 3800rpm, and can be increased to 6000rpm using magnetic field weakening technology, providing strong power output to meet the demands of high-speed driving. At 72V, the vehicle can reach a maximum speed of approximately 100kph, with excellent acceleration performance.

* Structural Design: The gearless design simplifies the transmission system, eliminating components such as a gearbox, drive shaft, and clutch. This saves space and reduces maintenance costs and complexity. Furthermore, the motor can be more conveniently installed at the rear of the vehicle, freeing up space for the battery.

* Lightweight and Protective: The use of lightweight materials such as aluminum alloy results in a relatively low overall weight, facilitating overall vehicle design and handling. It also boasts a high IP67 rating, making it dustproof and waterproof, suitable for a variety of harsh outdoor environments.

* Compatibility and Functionality: It supports dual Hall effect sensor and encoder feedback, making it compatible with a variety of controllers, such as the EM150. It also enables regenerative braking, further improving energy efficiency and vehicle braking safety.

Application Scenarios

* E-Bikes: It can serve as a power source for high-performance e-bikes, providing riders with powerful thrust, whether accelerating on city roads or climbing hills, enhancing riding pleasure and efficiency.

* E-Motorcycles: Suitable for e-scooters, its high power and high speed meet the speed and power requirements of e-scooters, making it suitable for urban commuting, short trips, and light off-roading.

* E-Scooters: For large, high-performance e-scooters, the QS138 3000W 70H gearless motor provides sufficient power for faster speeds and improved climbing ability, making it suitable for medium- and long-distance urban travel or use in areas with complex terrain. 

* Special vehicles: Such as electric karts, electric ATVs and other special vehicles, the high performance and compact design of this motor can well adapt to the needs of these vehicles, providing them with strong power support to meet the use of different scenarios such as competition or entertainment.
