How to Check Your Windings on Three Phase Motors

Motor windings are conductive wires wrapped around a magnetic core; they provide a path for current to flow to create then magnetic field to spin the rotor. Like any other part of the motor, the winding can fail.

How To Check Motor Winding Resistance On Single & Three-Phase Motors

Motor Circuit Analysis™ (MCA™) is a test method that determines the true state of health of 3 phase & single-phase electrical motors. MCA™ checks the motors coils, rotor, connections, and more. MCA™ can verify ac motor winding resistance as well as dc motor resistance and determine state of health.
