The TMdrive-50 is ideally suited for high-power, precision-controlled processes. Efficient, high current IGBT power devices and control cards are common to the drive family. The family targets specific customer requirements for:
High reliability
Simple configuration and maintenance
Low cost of ownership
Flexible arrangement of converter, inverter and cooling units allows for maximum power density, resulting in minimum floor space, and installation cost. The Insulated Gate Bipolar Transistor (IGBT) is used in the converter and inverter.
TMdrive-50 (3.3 kV) Features and Benefits
Design Feature
Customer Benefit
The control signal is voltage, not current
The IGBT requires very low power to switch, so control circuits are small, with few components and therefore low failure rate
High switching speeds less than 2 ยต per second
Very low switching losses and accurate control
Simple switching circuitry
Gate driver hardware is compact. Careful design has allowed traditional IGBT snubber components to be removed
