Variable speed drives Altivar Solar Option: Motor chokes

Presentation, references

Presentation Motor chokes Motor chokes, also known as load reactors, can be inserted between the Altivar Solar drive and the motor to: b Limit the dv/dt at the motor terminals (500 to 1500 V/µs), for cables longer than 50 m/ 164 ft b Filter interference caused by the opening of a contactor placed between the filter and the motor b Reduce the motor ground leakage current b Smooth the motor current wave form to reduce motor noise
