Operation of PWM-driven motors, such as servo and variable frequency drives (VFD), causes a number of problems in equipment, including damage to the motor’s bearings from leakage currents via electrical discharge machining (EDM) and to motor’s insulation. Strong EMI generated by PWM-driven motors causes errors in equipment and test equipment.
Electronic components processed on PWM-driven tools such tools as IC handlers, wire bonders, SMT pick-and-place machines and many others can be subject to electrical overstress (EOS), affecting yield and reliability.
OnFILTER’ SF-series filters substantially reduce high-frequency leakage currents in motors and in wiring, assisting in compliance with the requirements of IEC60034-17/-25. They also reduce interfering frequency noise within the tool resulting from operation of PWM-driven motors.
