A 7.5 kw motor it is rated current of the 15 ma,if beyond 3 ma affect electricity opportunities?

The motor is driven by a small centrifugal pump,bearing also just changed,center also from the new correction,disintegration of pump is no defect,but there is always the phenomenon of fever and excessive current and motor magnet motor noise? Please some directions No-load current of the motor is 20-50% of rated current commonly,if too much no-load current should undertake the following check. 1 phase voltage of the motor parts stator winding is high 2 whether take star wiring fault into Angle 3 motor air gap is too big 4 internal wiring for error 5 stator windings wire diameter is too small,6 7 of electricalmotor1.blogspot.com the rotor iron core is neat assembly quality is unqualified,whether bearing lubrication good 8 core weight too small nine winding inside do you have any short circuit,open circuit or ground fault for you is wrong,but I'd give you the answer,the 7.5 KW motor is impossible to 15 ma of current,should be 15 Ann,you electrical motor 24v put the motor no-load test run first to measure current if current is disposed of in accordance with the method of the above,if the current normal pump you have any question.
