Miniaturisation of electrical machines

Electrical Machines I

The speed of the machine has to be increased from zero and brought to the operating speed. This is called starting of the motor. The operating speed itself should be varied as per the requirements of the load. This is called speed control. Finally, the running machine has to be brought to rest, by decelerating the same. This is called braking. The torque speed characteristics of the machine is ...

Miniaturisation of Cardiovascular Devices

VAD’s can unburden the heart at an early stage even allowing for a complete recovery. However, the requirements for those devices are high. This includes, among others, long-term durability, safety and reliability, small over-all size, low power consumption, easy handling, adaptive control (patient need), and transcutaneous energy transfer. Especially for children and infants low priming volume...

Control of Electrical Machines for Drives

Electric drive systems are one of the most important components of our life; billions of them are used in industry, traffic applications and private environment. In the recent past an accelerated development of controlled drive systems could be experienced. The scientific and technical background of today’s most important drive systems, the converter controlled DC-drives and the vector controll...
