AC Synchronous motor :
Manufacturing Range : 2kg.cm to 75 kg.cm
Standard “ Sri-Syn” Synchronous Motors are permanent magenet. A. C. Single phase Motors having Instantaneous starting, stopping and reverseing characeristics. These have low speed of 60 R.P.M. At 50Hz supply.
Three leads types , require only a single pole, three position switch “ forwad “, “ rverse” and “ off ” controls. Starting
and running currents are same, so there is no excessive rise in current when motors are energised. Motors can be completely stalled without over heating. Starting and stopping is accomplished in less than 5 Deg. of shaft rotation, eliminating the need for any breaks.
Torque is directly proportional to R.M.S. Voltage and R.P.M. Is directly proportional to supply frequency. |
