Phenomenon Rotor Fault-Multiple Electrical Rotor Asymmetries in Induction Machines
IEEE Transactions on Power Electronics, 2010In the literature, the effects caused by a single or several adjacently broken rotor bars, or a broken end ring are thoroughly investigated. The phenomenon of various nonadjacently broken rotor bars has not been studied so far in detail. Since nonadjacently broken rotor bars may give rise to fault signatures, which are not directly related with the ...

Rotor Optimization to Reduce Electric Motor Noise
SAE International Journal of Advances and Current Practices in Mobility, 2023<div class="section abstract"><div class="htmlview paragraph">Electric motor is among the main sources of noise and vibration for electrified propulsion systems. This paper focuses on the electric motor rotor NVH optimization, which is identified as a key enabler to reduce the motor whine, and balances other performance such as motor torque

Internal rotor airgap-less electric motors
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017This paper proposes a new family of electric motors based on the concept of an airgap-less device with an internal rotor. The internal flux and therefore electromagnetic torque is maximized because the rotor is allowed to touch the stator. The proposed family of motors are competitive in applications where hydraulic motors are prevalent, i.e., low ...

Understanding rotor balance for electric motors
Conference Record of 2014 Annual Pulp and Paper Industry Technical Conference, 2014A balanced rotor is essential for smooth operation of rotating equipment. There are many factors that can cause unbalance in rotating machineries. This paper discusses some common causes of unbalance, different balancing methods and how they apply to rigid and flexible rotors, the difference and the relationship between balancing grades, vibration as a

ELECTRIC TUBULAR MOTOR WITH COMPOSITE ROTOR
Electric Machines & Power Systems, 1979Abstract An analytical and experimental investigation is presented for electric tubular induction motor having a rotor consisting of alternate rings of copper and steel mounted on a solid-steel core. A one dimensional-field analysis is carried out to study the effect of the different rotor parameters on the thrust.

Electric powertrain for helicopter tail rotor
2016 6th International Electric Drives Production Conference (EDPC), 2016The design of multi-phase permanent magnet brushless motor for an electrical helicopter tail rotor is introduced and described. The presented electric machine allows a substitution of the actual mechanisms in tail rotor system matching envelope, weights and performances. In order to obtain high torque with small overall dimensions of the motor, a spoke-

Electrical Rotors in the Heart
1991Electrophysiological processes in the heart are responsible for impulse formation and conduction. The normal action of these processes is necessary for the production of an efficient contraction. Interruption of impulse formation or conduction [3, 18] by either biological, pathological, or toxicological mechanisms can cause a disruption of the normal ...
