Assessment of torque components in brushless permanent-magnet machines through numerical analysis of the electromagnetic field [PDF]

, 2005
For the calculation of torque in brushless (BL) alternating current motors a local method is proposed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air gap.

Suppression of DC Winding Current Harmonics in Wound‐Field Machines Under PWM Excitation by Using Active Voltage Injection and LC Low‐Pass Filters

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, the LC low‐pass filter is designed and connected in parallel with the DC winding of the MFMWF machine to suppress the high‐frequency sideband harmonics in the DC winding current for the first time. The suppression effect is validated by experiments.

A Scalable FPGA‐Based Time‐Division Multiplexing Architecture for High‐Precision Synchronous Control of Large‐Scale Micro DC Motors

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
To address the limitations of traditional FPGA‐based multiaxis control schemes—such as excessive resource consumption and complicated parameter tuning—this paper proposes a large‐scale time‐division multiplexing (LTDM) control architecture. By leveraging dynamic resource scheduling and high‐fanout signal optimisation, the proposed architecture enables ...
