Different from the copper loss of general permanent magnet (PM) motors, the copper loss of ultra‐high‐speed permanent magnet motors (UHSPMSM) includes DC losses and eddy current losses, which lead to difficulty in analysis.

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]
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 ...

FIELD ORIENTED CONTROL ( FOC) FOR BLDC MOTOR [PDF]
The advent of DC or AC motors has revolutionized the industry. Over time the engine characteristics have been improved but the existence of brushes is still the major disadvantage.

Performance estimation of interior permanent-magnet brushless motors using the voltage-driven flux-MMF diagram [PDF]
The flux-magnetomotive force (flux-MMF) diagram, or "energy conversion loop," is a powerful tool for computing the parameters of saturated interior permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are not ...

Induction motor control through AC/DC/AC converters [PDF]
We are considering the problem of controlling inductions motors driven through AC/DC rectifiers and DC/AC inverters. The control objectives are threefold: (i) forcing the motor speed to track a reference signal, (ii) regulating the DC Link voltage, (iii) assuring a satisfactory power factor correction (PFC) with respect to the power supply net.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...
