The speed of a series motor with no load connected to it
increases to the point where the motor may become damaged.
Usually, either the bearings are damaged or the windings
fly out of the slots in the armature. There is a danger to
both equipment and personnel. Some load must ALWAYS be
connected to a series motor before you turn it on. This
precaution is primarily for large motors. Small motors,
such as those used in electric hand drills, have enough
internal friction to load themselves.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
