Reluctance
Synchronous Motor |
|
| |
Applications |
|
In applications
where accurate speed control and speed holding
is critical. They are extremely useful in applications
where speed synchronism between different machines
is required e.g. Synthetic fibre industry, glass
making machinery, textiles etc. |
|
| Some of the applications for which
these motors have been supplied : |
|
| |
For use in glass making
machinery --- Substitute for US &
German motors |
