TMEIC TMdrive-70
TMdrive-70e2 proizvođača TMEIC je izdržljiv i snažan pogon koji poseduje vodeno hlađenje. Primenjuje se za potpuno digitalizovanu vektorsku kontrolu indukcionih i sinhronih motora pomoću trostemene pulsne širinske modulacije (PWM).
TMEIC TMdrive-70 Features and Benefits
| Design Feature | Customer Benefit |
|---|---|
| IEGT power switch technology in the inverter and regenerative converter power bridges | High-speed switching coupled with the three-level power bridge delivers a smooth sine wave to the motor and power system. Low on-state IEGT voltage yields high efficiency |
| High-Speed Switching - The IEGT is switched at a rate of 500 Hz, even at power levels up to 10,000 kVA | Motor and Power System Friendly - Higher chopping frequency lowers the torque ripple in the motor and load, and lowers harmonics fed back into the power system. |
| Low power Gate Drive signals - used to turn IEGTs on and off. | Low power level voltage switched gate circuit has far fewer components than IGCT current-controlled gate, increasing inherent reliability |
| Frequency Modulation Control (not traditional PWM) power switching scheme and three-level power bridge control | Harmonics fed back into the power system are reduced to less than IEEE-519-1992 recommendations with no filters |
| Water-cooling technology for the power bridge | Reduced footprint, saving valuable factory floor space |
| Modular design of power bridge, with each phase leg having its own set of quick disconnects | Minimizes maintenance time |
| Control cards common to the TMdrive family | Reduces required spares and increases spares' availability |
