Application of Permanent Magnet Motor

Application of Permanent Magnet Motor: Application of Permanent Magnet Motor are given in Table 2.1. These properties are: residual flux density Br, coercive magnetizing force Hc maximum energy stored (BH)max and resistivity. Type A material is cheap but heavy, and suitable for low-rated production-run motors. Types B and C materials are hard and can be […]

Magnetic Properties of Materials

Magnetic Properties of Materials: Magnetic Properties of Materials – From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic materials are classified as paramagnetic ,μr slightly greater than 1, and diamagnetic, μr slightly less than 1. For all practical purposes, μr of these materials […]
