BRUSA Elektronik AG is offering its Planetary Traction Drive DTSP1—a fully integrated electric vehicle drivetrain combining motor and gearbox—with its higher power HSM1-10.18.22 Hybrid Synchronous Motor, offering 220 kW (295 hp) maximum power (145 kW/194 hp continuous) and up to 460 N·m (339 b-ft) peak torque (270 N·m/199 lb-ft continuous). With this configuration, BRUSA is targeting light commercial vehicles, vans or sports cars.
The compact design of the transmission in combination with the powerful motor results in a highly efficient power set. The DTSP1 unit can be used as an axle or four-wheel drivetrain set. By using the differential on the axles, powerful yet weight-optimized drives can be realized. With the adjustment of the axle differential every application can be achieved with the right ratio.
From a nominal speed of 4,400 rpm the motor—346 mm in length, diameter of 270 mm and weight of 76 kg—iprovides constant power to its maximum speed and a very high efficiency over a wide speed and torque range. The compact design of the gearbox when coupled with the HSM1-10.18.22 motor paves the way for an efficient yet powerful range of electric vehicles.
The gearbox is water-cooled and optionally equipped with a parking lock.
