Permanent magnet with MgB2 bulk superconductor

Superconductors with persistent zero-resistance currents serve as permanent magnets for high-field applications requiring a strong and stable magnetic field, such as magnetic resonance imaging (MRI). The recent global helium shortage has quickened research into high-temperature superconductors (HTSs)—materials that can be used without conventional liquid-helium cooling to 4.2 K. Herein, we demo...

Preparation and Characterization of MgB2 Superconductor

Superconducting MgB2 crystallites having a size up to 3 X 2 X 1 mm have been grown using a liquidassisted-sintering process under atmospheric pressure of argon. The magnetization measurements have been carried out on MgB2 samples to determine upper critical field, critical current density and irreversibility line. The obtained values of critical current density and upper critical field were ~10...

Brushless Permanent Magnet Servomotors

Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...

Controlled Permanent Magnet Drives

The considered converter-fed permanent magnet motor could alternatively be operated in two basically different states − the vector control mode or alternatively the brushless dc, also known as electronically commutated mode. Several quality aspects concerning the system performance have been comparatively investigated in practical as well as theoretical manner. Focus is thereby given to the num...
