Precise, reliable surface control of Induction or Permanent Magnet Motors
Levare variable speed drives (VSD) provide precision control and maximum protection of both induction and permanent magnet motors (PMM). Engineered with ESP and PCP applications in mind – Levare VSDs incorporate an array of advanced functions and control software algorithms plus data integration and remote communication interface capabilities

The Gas Lock Ride Thru function works to break or eliminate gas-lock conditions. When enabled and specific conditions of underload are detected, this application steps the drive through multiple predetermined speed levels until gas-locking conditions are overcome.
When in Clamp Mode, the Current Limit function acts to reduce motor frequency when motor current during operation exceeds a predetermined upper threshold. While in Target Mode, it acts as a PID regulator that can increase and decrease the frequency to maintain a desirable motor current level.
The Pump Unfreeze applications enable operator control to free a stuck downhole pump system by means of either controlled reversal of direction (JOG mode) or controlled application of variable torque level (TORQUE mode).
Superior reliability reduces drive
downtime
A wider range of lift system options using a single drive
Optimized motor efficiency with vector control for PMMs reduces OPEX
