Product Description

 Electric Motor Checker EMC-25Plus


  • Insulation Resistance Measurement (IR)
  • Identify open and short circuits/loose connections in a winding coil
  • Identify inter turn shorts.
  • Detect rotor bar problems without dismantling 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.
Fast Checks of On-Line Motors:

  • EMC-25 Plus is a portable diagnostic tool for Electrical Engineer and is used for quick on site checks of electric 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-25 Plus will immediately detect it, without having to dismantle the equipment.

  • The instrument has three separate operating modes to measure different types of fault like fully insulation, open circuits / loose connections, short circuits and rotor defects. Motor insulation is tested with a high voltage of 500V DC supplied by the instrument.
