Hot extruder motor

Hello,
please, i have ldo pancake motor at extruder and it is soooooooo much hot. It works well, only hot. Now, iam at current 0,2 (zero point two) and it is still hot, i can barely put my hand on it after hour print.
There must be something very wrong.
Iam using PERFORMANCE setting at printer config.
Thank you very much
