First, you've to see the nature of motor starting:<br><br>1. Is it started through a variable resistance in the rotor circuit? If so, see how fast is the external resistance brought down to zero. Is it pretty slow, that we cannot compare it with starting with a shorted rotor?<br><br>2. If (1) above is true, then is such a starting needed for the application? <br><br>If answers (1) or (2) above are negative, most probably, you could go for an induction motor, with proper ratings. <p>Narayanan UM<br><a href=mailto:umn@ieee.org>umn@ieee.org</a><br><a href= > </a><br>
