Dear All

I have to contol the speed of a single phase induction motor. I am new to motion control. I want to know the different methods used to control the speed of a single phase induction motor and what is the best method.I shall be very thankful if anybody can help me. If any body is having any document releated to speed control of the motors then please send them.

     I want to double-check, you have an AC Induction Motor (single or 3-phase?)  If that is the case, to control the motor the first thing you will needs is a drive. Unfortuntately, our drives do not work with induction motors. You will need to look at another manufacturer, at least for the drive.  Try to select one with either: Torque Based Analog Input Control Mode, Stepper Control Mode, or Peak Command Mode.  I know that Parker makes some drives with these characteristics.

    Also, you mentioned wanting to do velocity control?  If that is the only type of control method, the easiest way to control that will be to look for a drive with a serial port.  Then you could use LabVIEW or CVI with our VISA driver to write those commands. 

    I wasn't really clear what level of information you were looking for....if you have any questions, just let me know.
