Product Description

Electric Motor Checker EMC-25

Fast Checks of On-Site Motors:

  • EMC-25 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 will immediately detect it, without having to dismantle the equipment.
  •  The EMC-25 may also be used to check quality and condition of motors which have been in storage before they are installed.
  • 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 at 500V DC supplied by the  instrument
