TMdrive-XL Series
The TMdrive XL series family of variable frequency drives (VFD) provides
the high power levels and speed required to drive large motors that power
rotating machinery used in the Oil & Gas industry. Important VFD features
common to the family include:
•
Common architecture, pulse width modulation and control, water
cooling, I/O modules, and TMdrive-Navigator programming software
•
Multi-level VFD output for smooth waveform to the motor
•
24-36 pulse diode converter rectifier for low harmonic distortion
•
High VFD reliability and availability with MTBFs in excess of 20 years
and MTTR of less than 30 minutes.
•
Output frequency range high enough for direct compressor drive
with no gearbox, eliminating costly lube oil systems in addition to the
gearbox, resulting in increased system efficiency.
•
Up to 7.2 kV supply to the motor with no output transformer required
•
Ability to operate drive banks in parallel for higher power levels up to
120 MVA
