For these 2 devices what their power ratings are ? 1) single phase : AC 220V & starting amps 3Amps (i.e. starting torque) and the stabilized amps 2A ... For deep freezer 2) single phase : AC 220V & starting amps 2.7Amps (i.e. including the starting torque of a CRT monitor) and the stabilized amps 1 Amps thanks
1 2558We have .ht motor which is 60Hz.we run on 50Hz.so that it's speed reduce but we had one prob.that motor winding temp increase up to 135 deg.we want reduce this temp.what to do?we arrange ext.cooling fan but not much effect.we want reduce this temp. Inhouse without affecting much.cost. also don't want reWINDING OF MOTOR?
3 3728If a transformer primary winding operates at 240v, the secondary at 120v and the load is 1500w & the transformer is rated at 92% efficient, what's the current flowing through the primary winding of the transformer? What is the formula for finding this?
