Bonfiglioli 700CE planetary drives coupled with a high-power density electric motor are specifically designed for high-voltage hybrid powertrain systems. Many years of installation on crusher machines is concrete proof of the efficiency of these electric drive solutions. An integrated, maintenance-free IPM (internal permanent magnet) electric motor is included, giving significant benefits in terms of dimensions and efficiency. The motor design is flexible from a cooling type standpoint: 700CE series drives coupled with air-cooled motors are designed to be installed on all kinds of crushers and screeners, weighting up 60 tons and with a max. speed of 3.5 to 4.0 km/h. Because they use the same motor with liquid cooling, some of these solutions can also be applied to other types of new-generation off-highway tracked machinery in the construction industry. For outdoor use on rough soils, the motor protection class is IP67. The overall length of the SAHR brake, is particularly limited, close to the size of a hydraulic motor.
Benefits for OEMs • Ability to downsize and downspeed combustion engines • Ease of installation: electric solution dimensions comparable to standard hydrostatics • Higher system reliability: fewer mechanical parts • Virtually maintenance-free electric motors • From sprocket to electric wire with only one supplier Benefits for the end-user • Reduced fuel consumption • Increased productivity • Better machine maneuverability • The electric solution is cleaner: lower risk of oil spills
