    Soft starting a Single Phase Induction motor.

    The idea is to run the motor as a starter motor and then as a generator. A single phase output is needed. Reliability is an important issue, therefore diminished capacitor life is not desirable. I realise it is case dependant, but how severe is this capacitor wear? Are there other ways to soft...

    Soft starting a Single Phase Induction motor.

    The voltage flicker is significant when I start my single phase capacitor split motor. I want to use a soft starter on the motor, yet I fear that the auxiliary components or starting components will not be able to handle the applied voltage for a prolonged period of time and overheat. Does...

    Single Phase Induction Motor

    In a capacitor start induction motor, there are auxiliary capacitor and an auxiliary winding.

    Single Phase Induction Motor

    When the centrifugal switch operates on a single phase induction motor and switches off the auxiliary starting components and the motor is driven by an engine past 0 slip (so as a generator) do the auxiliary components have any affect on the operation of the generator?

    EN6100-3-3 Interpretation

    This section seems to be poorly worded and misinterpreted across the board. It states that the maximum Voltage fluctuations and flicker allowable is dc=3.3%. I assume this is refering to inrush current? Can anybody clarify this? How can one make this applicable to inrush? Can you give an...

    Harmonics query: Inner magnet 3 phase induction motor vs. Inner magnet single phase motor

    Thanks for your response. Could you give a brief explanation about why inner permanent magnet machines create less harmonics than their wound rotor equivalent? Or is this the case? I have "The Induction Machine Handbook" but find this quite daunting.

    Harmonics query: Inner magnet 3 phase induction motor vs. Inner magnet single phase motor

    Hello, I am trying to compare the effects of harmonics on 3 phase induction motor against a single phase induction motor of the same size and under the same constant torque operation, negative torque (operation as a generator.) Does anyone have any sources that could help me on this issue. Also...
