The use of high torque and high power motors resulted in FISCHER becoming involved with converter technology. With a modulation frequency of 40 kHz, a usable current up to 300 A (RMS) and an integrated industrial PC, FISCHER’s Smart Drive converteraccommodates today’s requirements of merging spindle and drive into one mechatronics system. The new product should be considered as a “plug-in” that contains all information relating to the spindle operation and its monitoring functions.
When compared to existing converters, FISCHER’s Smart Drive outperforms the others in high speed and high power cutting applications as its high modulation frequency allows for the maximum spindle power at maximum speed. Limitations due to De-rating effects can be neglected since they do not exist in this configuration.
