This paper formulates the difference in base frequency and maximum torque between distributed and concentrated windings taking into account the air-gap modulation of concentrated-winding permanent magnet (PM) motors. The design superiority is typical

A novel criterion for the utility of reluctance torque in permanent magnet (PM) motors is developed. The criterion, reluctance torque ratio α , can be quantified by using the PM flux linkage Ψ p of the stator phase windings, the current I , and the

This paper proposes a drive control method for a linear compressor driven by a linear motor. Generally, the efficiency of a linear motor itself is relatively lower than that of a rotational motor. However, higher efficiency should be achievable by ad

Higher efficiency for a linear motor should be achievable by adding assist springs and driving the motor at the resonant frequency, even if the efficiency of the motor itself is relatively lower than that of a rotational motor. When using a linear mo

A novel structure for a ferrite-magnet motor was derived from new criteria for the utility of reluctance torque, based on the permanent magnet (PM) flux linkage of the stator phase windings, the current, and the direct- and quadrature-axis inductance

In an AC-DC-AC motor drive system, a beat phenomenon of the motor current occurs, especially in the over-modulation range with DC-link voltage ripple and low frequency carrier. We analyze this beat phenomenon and propose two beatless control methods.
