The output voltage and current waveforms produced by PWM drives place stresses on motor insulation systems. PWM waveforms contribute to increased thermal, vibration and dielectric stresses. TCI products protect your motor from voltage spikes and overheating.
KMG with PQconnect sine wave filter converts the PWM wave form to a near sinusoidal wave form by eliminating the carrier frequency. PQconnect connectivity detects thermal switch alerts, monitors the filter performance, and verifies voltage distortion is at a recommended level.
TCI’s MotorShield (MSD) sine wave filters are used on the output of a VFD/drive to filter the PWM carrier frequency converting it into a clean voltage waveform. The MSD is suitable for carrier frequencies from 2 – 16 kHz. The MotorShield sine wave filter offers an added level of protection to your motor with minimal voltage drop.
KDR line reactors are electrical components that help to protect 6-pulse rectifiers and power conversion devices such as variable frequency drives (VFDs). When used in conjunction with a VFD, a KDR line reactor can help reduce harmonics and protect the drive from harmful voltage spikes.
