Probable fault cause
Overcurrent
MicroMax180 limits the current at 2.4 A and trips then after 4-5 s.
- The motor is too small in relation to rotor diameter
- Rotor rotation sluggish
- Damaged motor, e.g. bearing fault
Measure current.
NOTE! Precise voltages and amperages can only be obtained with a
moving-iron instrument.
