Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFStarting Performance of squirrel cage Motor:
- For constant speed service where the starting duty is comparatively light and infrequent, the squirrel cage IM is best suited.
- Starting performance of the cage motor varies considerably with its design.
- A typical squirrel cage Induction motor would have 130% starting torque and 600% starting current when started Direct-on-line.
- A high starting current causes a heavy drop in line voltage and adversely affects the operation of other motors connected on-line. For this reason, it may be required to restrict the starting current of motors.
