Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]
, 1996 This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

Modeling of ZSI based BLDCM For Reduction of Commutation Torque Ripple
HELIX, 2020 This paper proposes a new technology, which reduces ripple context in Brush less DC Motor. This technology is having the similar modulation modes in conduction period and commutation period. In Grid applications, Brush less DC motor produces a torque ripple, hence for the reduction of ripple content, a ZSI based BLDCM is proposed in this technology ...

Summary of electric vehicle dc motor-controller tests [PDF]
, 1982 The differences in the performance of dc motors are evaluated when operating with chopper type controllers, and when operating on direct current. The interactions between the motor and the controller which cause these differences are investigated.
