I have a series DC Motor which it's armature draw about 10 amp. with high RPM (17000) at 32 V input voltage. This motor also have brake coil in series with field coil which draw about 2 amp when energized.
I need to know what are the possible causes for the high current and RPM in the armature?
DC motor spec. are as follow: Input: 24-32 DC Run Current: 4 Amp Max RPM: 14000 Max.
