Motor Magnetics are used on electrical machinery to prevents tools from restarting after a power loss occurs and power is subsequently restored.
OSHA 1910.213(b)(3) states “On applications where injury to the operator might result if motors were to restart after power failures, provision shall be made to prevent machines from automatically restarting upon restoration of power.
Not sure if your machine has magnetic contactors? Start the machine, unplug it while running. If the machine restarts when plugged back in, it does not have magnetic contactors. If your machine can present a hazard to an operator when it restarts by itself, current safety standards mandate that it must be equipped with power outage protection to control this hazard.
