LLC "Lex"Description
DOWNHOLE PM MOTORS WERE DESIGNED TO:
Increase downhole motor efficiency up to 93 %
Decrease cable losses by 25 – 40 %
Decrease surface equipment losses by 5 – 10 %
HIGHER EFFICIENCY
Permanent magnets in the rotor eliminate electric & magnetic losses involved with a “squirrel cage” in induction rotor
The stator flux penetrates only to the depth of the rotor magnets, unlike the induction motor
MINIMIZED DEGRADATION OF INSULATION
Achieved due to lower wasted heat amount and start-up current
LOWER TEMPERATURE RISE
No need to stop for cooling when ramping-up
Lower scaling risk
Lower requirements for seal temperature rating
Higher reliability and longer runlife
RELIABLE INTERMITTENT OPERATION
COMPACT DESIGN & HIGHER PASS-THROUGH DLS AVAILABLE
Achieved due to higher power density in rotor
