Control torque of 3 phase motor

Dear all,


This is a newbie asking for some information.


Actually, we have 1x30HP, 2x10HP motors working at our workplace. When we start the motors there is a lot of torque generated due to which our grid supply charges us penalty every month.


We need information about the device(s) that are used to control the torque.


While doing some research, I got to know that I can get myself set up control panel that has capacitors either separately on each motor or on my 100kva transformer. This will control the torque as well as give me saving on electricity bill.


Kindly help in this regards.
