Stepper Motor Filters
PWM-driven motors, such as stepper motors are a major source of electromagnetic interference (EMI) in equipment. They also cause a number of problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation.
OnFILTER’s patented TF/TV-series filters stepper motor filters substantially reduce high-frequency leakage currents in motors and in wiring, assisting in compliance with the requirements of IEC61800-3, IEC60034-17/-25 and NEMA MG 1-2016, as well as with NAMUR recommendations. They also reduce interfering high-frequency noise within the tool resulting from operation of PWM-driven motors.
TF/TV series filters greatly reduce high-frequency currents on equipment ground, as well as overall EMI in the tool, lowering risk of EOS and reducing errors in automated equipment and testers.
No mechanical attachments
No changes in software
No Mechanical Fitting, No Wear, No Maintenance
OnFILTER' TF/TV series filters have no mechanical coupling to the motors - all connections are electrical. Their cost of ownership is zero.
