DC bus drives system gets DTC performance

ABB has launched the ACS 600 MultiDrive, which combines DTC (direct torque control) performance with operation on a DC bus.

ABB says that the accurate torque and speed control from DTC promises to eliminate the need for feedback devices on many DC bus drive systems applications.

The MultiDrive has a wider power range than previous systems 5kVA to 33kVA compared with 9kVA to 1500kVA.
