| Centrifugal Gear |
:
|
The specially designed electronic starting switch fitted in terminal box. Motors can be manufactured and supplied with permanent split phase, capacitor start and run also i.e. without centrifugal gear and open circuiting switch.
|
| Open Circuiting Switch |
:
|
The open circuiting switch operated by the centrifugal gear has bimetal contacts of silver and copper and mounted on high quality phosper bronze supporting arm. |
| Winding Protection |
:
|
Embedded of PTC thermisters in the stator windings is feasible on request. |
