... so a PMDC motor will have a lower induced torque per ampere of armature current than a shunt motor of the same size. (b) PMDC motors run risk of demagnetization due to A.R. effect which reduces overall net flux, also if IA become very large there is a risk that its mmf demagnetize poles, permanently ...

... In [15] and [16], the concept of an active IPT was first pro-posed in 12-pulse and 24-pulse diode converters, which im-proved the line quality by injecting compensation current into the extra winding of the IPT with a low kilovolt-ampere rating inverter. However, the control strategy used in [15] on ...

Understanding Motor Nameplate Information NEMA
... NEMA requires a manufacturer's type, but there is no industry standard for what this is. It is sometimes used to define 1 or 3-phase; single or multi-speed; construction, etc. The "type" definition varies from manufacturer to manufacturer. Below are some of the "types" of motors that may be encounte ...

... To understand the origin of bistability in an electropermanent magnet, it is helpful to examine the B/H (magnetic flux density vs. magnetic field intensity) plot shown in Figure 5. This is derived by adding the B/H plots for Alnico V and NdFeB, since the two magnets have the same area and same lengt ...

... Activities using magnets can feature at all levels. Students will have some knowledge of magnets, since they are common around homes, but students often expect magnets to attract any metal object rather than only iron and steel. Magnets have no effect on aluminium, brass, silver or copper. Students ...

repetitive current controller for grid
... When the references Id∗ and Iq∗ are all equal to 0, the generated voltage should be equal to the grid voltage, i.e., the inverter should be synchronised with the grid and the circuit breaker could be closed at any time if needed. In order to achieve this, the grid voltages (uga , ugb and ugc ) are f ...

electrostatic potential and capacitance
... The charge placed on a conductor is always distributed only on the outer surface of the conductor. We can understand this by the fact that the electric field inside a conductor is zero. Consider a Gaussian Surface shown by the dots inside the surface and very close to it. Every point on it is inside ...
