Optimization and Experimental Validation of Amorphous Alloy High-Speed Asynchronous Motor for Simultaneous Reduction on Core and Copper Losses

IEEE Access, 2023
Amorphous alloy has been proposed to replace silicon steel as the stator core material of high-speed asynchronous motors so as to reduce their core losses. However, it is found that this is at the expense of increasing the copper loss.

IMPROVING SUCKER ROD PUMP EFFICIENCY USING FREQUENCY CONTROLLED INDUCTION MOTOR

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022
Relevance. In sucker rod pump installations, the cost of the prime mover’s power use has substantial effect on the overall operational cost. Reduction in power consumption can lead to reduction in operating cost. Hence, as the sucker rod pump is dominant

Breakdown of the dipole approximation in core losses

Ultramicroscopy, 2011
The validity of the dipole approximations commonly used in the inelastic scattering theory for transmission electron microscopy is reviewed. Both experimental and numerical arguments are presented, emphasizing that the dipole approximations cause significant errors of the order of up to 25% even at small momentum transfer.
