Flexible Architecture and Scalable Power Conversion

Engineered for versatility, the TMdrive-70 supports both induction and synchronous

motors and offers a choice between active regenerative or diode-based

non-regenerative AC-to-DC converters. Available in power levels from 5.000 to

40.000 kVA at 3.3 kV, it meets stringent IEEE-519-1992 harmonic guidelines while

integrating seamlessly with TMEIC’s control ecosystem, including the PP7 processor

and TMdrive Navigator tool. With scalable inverter and converter configurations—

including parallel arrangements of the TMdrive-D70 and TMdrive-P70—the TMdrive-

70 delivers unmatched control, flexibility, and reliability for high-capacity operations.
