This paper compares various electrical motors being used in a residential electrical appliances. Most of those motors are induction/DC/universal motors and their efficiency levels are very low. It is an urge to develop a motor with higher operating efficiency. With the recent development in the field of power electronics and magnet technologies, it would be possible to meet the above requirements...
Mixer grinder in a residential application works with a 230V 1phase AC supply and at present it operates with an universal motor. The efficiency of this motor is in the range of 40 ∼ 60%. At the wake of improving the efficiency with more reliable and easy control, the possibilities of BLDC motors in the application is explored. The design of a BLDC motor with a surface mounted rotor and interior permanent...
Permanent magnet synchronous machines (PMSM) are being used in numerous applications. Some of requirements need a single machine to operate, below and above the rated speeds. As there is no direct field control method in a permanent magnet (PM) rotor, injection of negative direct axis current is done to implement a flux weakening, which in turn, helps to achieve speeds beyond the rated speed. An alternative...
