Siemens develops new low-weight, high-power electric motor for aircraft; enabling larger hybrid aircraft 24 March 2015 Siemens researchers have developed a new electric motor that, with a weight of just 50 kilograms (110 lbs), delivers a continuous output of about 260 kW—five times more than comparable drive systems. The motor was specially designed for use in aircraft. Due to its record-setting power-to-weight ratio, larger aircraft with takeoff weights of up to two tons will now be able to use electric drives for the first time, Siemens said. To develop the motor, Siemens’ experts scrutinized all the components of previous motors and optimized them up to their technical limits. New simulation techniques and lightweight construction enabled the drive system to achieve the weight-to-performance ratio of five kilowatts (kW) per kilogram (kg). Since the new motor delivers it...
