Servo vs. Mechanical: Press Maintenance

"A question I often hear: What is the anticipated life expectancy for high-torque/low-RPM servo motors, and what maintenance is required compared to the relatively simple EC or VF motors on mechanical presses? This, of course, can vary depending on the manufacturer and the number of motors utilized. What we can now say is that, with more than 20 years of service in the field, the life expectancy of DSF servo motors will exceed 25 years before requiring rebuild/replacement, with only minimal maintenance over their lifespan, such as replacing blower fans and air filters."
