Phase Rotation Checker SOKEN DAC-PR-2S

Phase Rotation Checker

SOKEN Phase Rotation Checker DAC-PR-2S provides a non-contact means of detecting and displaying the direction of rotation of motors. The direction of a motor’s rotation can be determined even if the rotor is visually hidden or absent, because this instrument senses the phase rotation of the leakage field of the motor’s rotating magnetic field.

The direction of rotation of a DC motor also can be determined when its rotor is in motion, generating a rotating magnetic field.

In addition, this phase rotation checker can be used for any kind of equipment that generates a shifting magnetic field, such as a linear motor.
