GEM IN-WHEEL DRIVE

GEM in-wheel drive represents an advanced propulsion system for urban electric vehicle applications, using innovative modular multiphase GEM technology. It is suitable for electric two, three and four wheeler applications and robotic vehicles due to modular mounting options and different speed versions. Fully integrated drive operates in a low voltage regime with a simple air cooling system. Patented modular design allows the development of a complete product range at the power level from 1 kW to 15 kW and can be customized to special requiremetns.
