1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

This paper introduces a new dual stator hybrid brushless vernier motor. The rotor is of hybrid nature i.e. it has windings as well as the magnets. To make it brushless for the rotor winding, an already developed brushless technique is employed. Two different configurations for placement of magnets are discussed, interior permanent magnet (IPM) and surface permanent magnet (SPM). Hence, the topologies under investigation are dual stator hybrid interior permanent magnet vernier motor (DSH-IPMVM) and dual stator hybrid surface permanent magnet vernier motor (DSH-SPMVM) intended for direct drive applications. The inner stator contains two windings (Main three-phase "ABC" winding and an additional single phase "X" winding) while the outer stator contains only three phase "ABC" winding. The rotor has two sides; the inner side of the rotor has windings placed on it while the outer side has PMs (either interior or surface mounted). The inclusion of both brushless windings and PMs allow for hybrid configuration which helps to increase the overall torque of the machine. Simulation results in ANSYS Maxwell demonstrate that the DSH-SPMVM achieves a superior average torque of 44.19 Nm at low speed (524 rpm), while the DSH-IPMVM offers a 31.58 Nm torque output with a significant reduction in torque ripple, achieving nearly 89% less ripple at high speeds (1200 rpm). Both models maintain high efficiency levels above 90% under rated conditions. To validate and compare the models, both designs are analyzed using computer simulations in ANSYS Maxwell.
