GEM TECHNOLOGY
GEM motors has developed patented modular multiphase technology for advanced GEM in-wheel drives. This solution is leading the future of e-mobility technology trend towards a completely integrated electric motor drive that is close to the wheel. With this technology, we simplify the vehicle electrification and minimize the number of parts, while at the same time reducing weight and space.
ADVANTAGES
EXCELLENT SYSTEM EFFICIENCY
- Up to 20% driving range increase due to improved integrated motor electronics and lower copper losses
- Up to 10% reduced energy consumption due to motor regeneration feature
SUPERIOR PERFORMANCE
- Unique smooth operation due to multiphase motor operation with FOC control
- Excellent climbing ability and fast acceleration due to high starting torque
SAFE AND RELIABLE ELECTRIC DRIVE
- Human safe low voltage operation below 75V DC
- Less electromagnetic emission up to ten times compared to other solutions
ADVANCED AND SMART SOLUTION
- Optimal space and weight saving solution with a minimum number of parts
- Fully integrated and modular direct electric drive solution for variuos applications
COMPARISON
Current state-of-the-art electric propulsion for Small and Light Electric Vehicles available on the market and comparison to GEM in-wheel drive.
The in-wheel solution introduces some significant advantages compared to the central motor with transmission, which is a rather heavy and complex propulsion system. GEM in-wheel drive offers an optimized direct-drive propuslion with high torque and increased overall efficiency. It is in line with future trends of highly integrated solutions, reducing weight, space and number of parts for electric propulsion.
