TMdrive-80 – 3.3 kV, up to 48 MVA

The TMdrive-80 from TMEIC is a high-power, water-cooled, precise and rugged fully digitalized vector controlled three-level pulse width modulated (PWM) induction and synchronous motor drive system. Power output levels of more than 50,000 HP are available.

The TM-80 uses proven integrated gate controlled thyristors (IGCT) power switching technology, in a three-level configuration.  Flexible arrangement of converter, inverter, and cooling units gives high-power density and a small required floor space and lower installation costs. 

Applications
The high-power TM-80 can be used in many applications, including:

• Precision-controlled processes with high dynamic performance requirements such as large metal mill main drives.
• Very large fan, compressor, and pumping applications. The TM-80 provides accurate speed control and high efficiency while eliminating the need for high maintenance mechanical flow control devices.
• Grinding mills with high overloads and impact loads.
• Mine hoists, with high overloads and overhauling loads.

• Power levels 5000 kVA to 48,000 kVA at 3300 output volts (any output voltage through output matching transformer)
• Low harmonic distortion to the power system – meets IEEE-519-1992 guidelines
• Induction or synchronous motor compatibility
• Uses the TMEIC family common control platform, including PP7 microprocessor, control I/O, and the TMdrive Navigator toolbox

• TMdrive-80 inverters that can be paralleled up to 48,000 kVA capacity
• TMdrive-P80 regenerative AC-to-DC converters that can be paralleled in combination with inverters up to 48,000 kVA capacity
