Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

Question 1

Radioactivity is the process by which unstable isotopes of elements disintegrate in the nucleus to release energy in form of gamma rays, beta radiation and alpha radiation. The disintegration occurs as a result of the stability within the cell nucleus. Some isotopes of elements have non-balancing number of the protons as compared to the neutrons, as a result of the lack of balance between the negative and the positive charges in the nucleus; the nucleus becomes unstable and disintegrates. Radioactive radiation was first discovered by Henri Becquerel in 1896 as he was working on X-ray. By then the X-ray ...
