units for the truck and bus industry – such as for Volvo’s Hybrid bus. Considering the company also serves the AGV market with specially equipped complete drives units this demonstrates a truly broad spread of application areas covered.
Innovative Solutions With a wide range of electrical drives and generators, the portfolio includes complete hybrid systems optimized for high energy efficiency as well as single traction, pump and steering motors alongside motors for propulsion and steering.
“Our future high endproduct will be our permanent magnet synchronous motor/ generator” explains Mr. Haag. The product is maintenance free, high protection class (IP69), oil cooled and has an impressively high efficiency rate exceeding 95 per cent. These new modular concept motor/generators have a high torque density and a current power range of 17 – 200kW - with higher power levels being in the development stage. This motor almost fits on an A4 sheet and yet delivers 200kW of power. Many people see the machine and think they might be lucky to get 30-40kW out of
it – they don’t believe their eyes when they look at the label!” This motor has several potential applications from power generation or propelling traction drives to other uses as an auxiliary function. Schabmüller is also driving forward the development of permanent synchronous motors for agricultural applications. Most implements in the agricultural market are still driven hydraulically but as Mr. Haag explains, “There will be a change from hydraulic to electric in the agricultural and construction market. A generator on the main machine would be useful as this would
