Electric Motor, Generator and Transformer Trouble Shooter

Know in a few minutes what the problem is: Electrical or Mechanical

Complete Condition of your STATOR, ROTOR, Coil, Connections, internal fault or ground fault

Electric Motor Checker EMC38A Main features:

  • Very handy
  • Light Weight
  • ABS Plastic Cabinet
  • Built-in Rechargeable battery pack
  • Insulation Resistance (IR) Measurement
  • Identify open and short circuits / loose connections in a winding coil
  • Identify interterm shorts
  • Detect rotor bar problems without dismounting the rotor
  • Inductance of the winding with respect to different positions for rotor for detecting blow holes or cracks in the rotor bars.
  • Simple operation, accurate & quick assessment of motor condition.
  • Low battery Indication


Regular testing can identify developing faults before a failure occurs. All measurement data can be trended for predictive maintenance condition monitoring. By making proactive repairs and eliminating unscheduled down- time , plant productivity is greatly improved.

EMC-38A is a Digital portable diagnostic tool for Electrical Engineer and is used for quick on - site checks of electric motor and other three - phase machines. A reduction in machine performance, such as inefficient operation or tripping of overloads, may indicate mechanical or electrical faults. If the fault is electrical the EMC-38A will immediately defect it, without having to dismantle the equipment.The instrument has three separate operating modes to measure different types of faults like fully insulation, open circuits / loose connections, short circuits, Ground faults and rotor defects. Motor insulation is tested with a high voltage of 500V & 1000V DC supplied by the instrument.
