Hello Everyone ..
I have a dual speed motor 1.9kw/6.5kw Star/Star 975rpm/1455rpm .. Now the present condition is that there is a 6 core cable connected to motor and that cable 3 core goes on one contactor(1 speed) and another 3 core is connected with the second contactor (2 speed),
first the small speed get start then there is a timer and change to second speed .... Now I am planning to remove all these contactors and just install a 3 phase inverter.
What I think is that I should just use the 2 high speed 3 cores and connect it to the inverter output , and just modify the acceleration and deacceleration time in inverter as per my requirement. ( and Just remove the 3 cores of the 1 low speed from the motor terminals )
Now my question is that I have never done that before..I have installed many inverters and motors but never modify like this so I am confuse.
Please clear me whether I am right or dual speed motor is something different and cannot be connected with the inverter.
