Variable speed drives are the most effective solution for applications requiring motor operation at different speeds.
Advantages of using VSDs:
Avoid additional protection circuits as long as these protections are built in; Keep motor supply levels consistent; Permit high torques for starts/stops and enable the motor to run at the optimum performance point.
In order to minimise total losses in the motor, WEG variable frequency drives offer the exclusive Optimal Flux® condition resulting in higher efficiency, lower operating temperatures and, consequently, longer lifetime.
