Danfoss Electrification Drives

Danfoss Mobile Electrification Motors Danfoss

Danfoss Mobile Electrification motors and generators are water-cooled SRPM (synchronous reluctance permanent magnet supported) motors. This technology produces very high torque at both low and high speeds, making the motors particularly suitable for travel drives. The power range extends from 40kW to 1200 kW in the sizes PowerDRUM XXS, XS, M, L. They are mostly used in combination with Danfoss Mobile Electrification Inverters. Due to a special motor production technology and optimized software, a high efficiency at nominal power is guaranteed.

Following features characterize the motors/generators:

  • SRPM Technology
  • compact and robust design
  • efficiency of ~95
  • Speed up to >4000 min-1
  • Torque of up to 6800 Nm
  • Water- or water/glycol-cooled
  • Standard SAE flange
  • long service life
  • protection class IP65

Typical applications:

Travel drives (buses, wheel loaders, trucks, cranes, trains), shredder drives, marine (ship drives), mining, forestry, agriculture, construction industry

Danfoss Mobile Electrification Inverter Danfoss

Danfoss Mobile Electrification inverters are water-cooled AC/DC inverters called PowerMASTER. DC/DC converters are also part of the DME range - they are called PowerBOOST. The power range of the inverters extends from 100kW to 300kW, with parallel connections up to >1000kW These inverters are characterized by their compact size and low weight. In combination with DME motors, the inverters can be optimally adapted to their application.

The inverters are characterized by the following features:

  • very compact design with only 15 Kg at 300kW
  • protection class IP67
  • high efficiency,
  • Water- or water/glycol-cooled
  • Operating range from -40°C to +105°C
  • Permissible shock load up to 50G


Typical applications:

All-electric or hybrid drives in trains or on mobile machines (excavators, wheel loaders, trucks, buses, ships, etc.)
