Superior Solutions for Typical Problems
To increase energy savings and decrease maintenance, many industries have begun to incorporate Pulse Width Modulated (PWM) Drives into various applications and processes. However, as the voltage spiking increases, so does the rate of motor failures.
For example, peak voltages on a 480 V system can reach an alarming 1,600 V. These high peak voltages will quickly cause a rapid breakdown of motor insulation, leading to motor failure. Which means that while initially your PWM Drive was saving you energy and maintenance costs, you may now need to replace your entire motor, or more costly sensitive equipment.
Instead, with TCI’s MotorShield in place, your system performance is improved by protecting your motor from the harmful effects of reflected waves, and further preventing motor failure associated with insulation failure, overheating, and audible noise.

Second Day Shipping Available
Most 480 V MotorShield sine wave filters (up to 305 amps) are available with the option of second day shipping. For 600 V applications and higher amp rating, please contact us for more details.
For Demanding Constant Torque Applications
For demanding constant torque applications, we recommend the MotorGuard Sine Wave Filter. This robust, heavy-duty filter delivers reliable sine wave filter performance where a filter with greater application flexibility and performance is needed.
Properly sized and applied, the addition of a MotorShield Sine Wave Output Filter is guaranteed to bring the application into compliance with NEMA Standards Publication No. MG-1. If the system fails to meet MG-1 standards with the addition of a MotorShield filter, TCI will take back the output filter and pay shipping both ways. This offer is valid for 60 days from installation date.
