The QS Motor QSJ138D-90 V3 is an advanced internal rotor PMSM solution designed for those who value performance and reliability. With a rated power of 4000 watts and a peak power of 13.5 kW, this unit is able to accelerate a light electric motorcycle or enduro to an impressive 100 km / h. The maximum torque of 150 Nm provides excellent traction at low revs and the ability to confidently overcome lifts up to 25 degrees even with full load.
>Smart design and space saving>
The key feature of the model is the presence of a built-in gearbox with a gear ratio of 1: 2.35. This engineering solution allows you to completely abandon the complex transmission, clutch and drive shaft, which significantly reduces weight and simplifies the assembly of the bike. The vacated space in the frame can be effectively used to accommodate an additional traction battery. In addition, the motor supports the regenerative braking function, returning energy back to the battery when slowed down.
>Reliability and protection from external influences>
The engine is equipped with an efficient air cooling system and KTY83/122 thermal sensors, allowing it to operate in a wide temperature range (up to 120°C in operating mode). The IP67 protection class ensures the complete tightness of the body, which makes this engine an ideal choice for use in off-road, mud and rain conditions. The kit provides high-quality waterproof connectors and reinforced phase wires with a cross section of 20 mm2.
