Maintenance and Care of Superconducting
Drive Unit
The LevTech DB-200E Superconducting
Drive is designed to operate 24/7 mainte-
® 3D nance free. However, to minimize the wear,
it is recommend that the drive be unplugged
if it is not in use for more than 24 hours.
Each time the drive is to be used, it is
necessary to charge the superconductors.
The drive should not operate continuously
for more than 10 days without recharging
the superconductors. To recharge supercon-
ductors the machine must be unplugged for
at least 25 minutes. Then follow charging
procedures in section 5.
