 The TMdrive-80 (TM-80) from TM GE 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.
General Specifications
The TM-80 drive includes a fully digitalized vector controlled three-level pulse width modulated (PWM) inverter and the choice of either an active regenerative AC-to-DC converter
