Motor Control Project AN1292 Motor Voltage Problem

Hi,
I use AN1292 Application note for PMSM  motor(230V, 4Pole, 2900RPM, 8.5A) Control Project my motor work in the closed-loop but getting problem in for the Voltage, I checked motor with another drive on 25Hz Frequency it gives 78V but my controller gives 61V, I want to increase my motor output voltage how can I do that.
As my motor output voltage is minimum at 82Hz frequency my motor taking high current and it halts so I want to increase Motor output voltage.
I try to change motor Voltage constant factor for increase voltage it does not work please give me a solution if anyone works on the motor control.

    Yu're not very clear ... and a lot of information is missing.
     
    The first question to answer:
    • What's the rating of your power supply (V and A) ?
      Or maybe the rating of your power stage (V and max. A).
    And may I assume your motor is 230 V / 2 kW ?

    PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)

    Motor Power Rating id Voltage: 230V AC, power: 2.2KW, Current: 8.5A RMS ,
    And Power Rating of Power stack: 230V ac and DC Bus is 325VDC and Max Current / Peak Current 25A.

    Thanks for the reply and informing us of success. Can you supply a little more information, such as a portion of code you may have changed, for the benefit of others who might benefit? :)
