hello community , 

i am facing some issues while driving an 3v bldc motor with IHM17m1 . motor is running with the torque control mode 

when change medium (when i dipped in water) it is working but its speed is reduced . i know my motor can go up tp 0.55A torque but its only taking 0.24A (imp :- in motor pilot the torque is showing 0.55A but actually its taking only 0.24A i dont know why its showing like this even after putting correct motor parameters).

i want to run the motor in maximum torque and maximum speed in different meadium , torque control mode is good for it or not (speed control mode showing speed feedback issue when its starting the closed loop)

*attaching the motor condition in air and water below
