Operating an electric motor in saturation – mechanical vibrations and other effects
| Nome: | Descrição: | Tamanho: | Formato: | |
|---|---|---|---|---|
| This paper addresses some of the effects of running an electric motor near and in the saturation zone of the electromagnetic hysteresis curve, namely mechanical effects such as mechanical vibrations and rotation speed apart from the classic electrical and thermal effects. Mechanical vibrations are intrinsically characteristic of rotating machines, and other turbomachine characteristics, such as rotor unbalance, non-linearity and shaft variable stiffness can introduce severe disturbances in the operation of the machine. Rotation speed is also affected by electric parameters, when the mechanical machine is connect to an electric machine, meaning both the electric machine type and the process by which it is driven affects both the value of speed and its constancy. | 541.8 KB | Adobe PDF |

This paper addresses some of the effects of running an electric motor near and in the saturation zone of the electromagnetic hysteresis curve, namely mechanical effects such as mechanical vibrations and rotation speed apart from the classic electrical and thermal effects. Mechanical vibrations are intrinsically characteristic of rotating machines, and other turbomachine characteristics, such as rotor unbalance, non-linearity and shaft variable stiffness can introduce severe disturbances in the operation of the machine. Rotation speed is also affected by electric parameters, when the mechanical machine is connect to an electric machine, meaning both the electric machine type and the process by which it is driven affects both the value of speed and its constancy.
