The Mercedes-Benz EQB - powerful and efficient double at the start

The EQB starts as the EQB 300 4MATIC with 168 kW and as the EQB 350 4MATIC with 215 kW. The ranges according to WLTP are each 419 kilometers. Further variants for special customer requirements will follow, including a particularly high-reach version. An asynchronous machine is used on the front axle. The electric motor, a gearbox with a fixed ratio including differential, the cooling system and the power electronics form a highly integrated, compact unit - the electric drive train (eATS). In addition, the EQB 300 4MATIC and EQB 350 4MATIC have an eATS on the rear axle with a newly developed permanent magnet synchronous machine. This is particularly compact. In permanent magnet synchronous machines, the rotor of the AC motor is equipped with permanent magnets. The magnets - and thus the rotor - follow the rotating alternating current field in the windings of the stator. The motor is called synchronous because the rotor rotates at the frequency of the stator magnetic field. The frequency is adjusted in the frequency converters of the power electronics to the speed requirements of the driver. The advantages of this design include high power density, high efficiency and high power constancy
