Frequency Inverter

Stepless speed control of three-phase motors is very important for the productivity and the durability of electric drive. With the help of frequency inverters, one achieves a constant uniform quality of drive train. The inverter generates a voltage of alternating current, which can be adjusted in amplitude and frequency. The three-phase motor is driven by means of this "re-targeted" voltage. Depending on the area of application, there are different types of frequency inverters. For example, for use in pump and fan applications in building technologies or in servo drives in industrial robots and production machines. With the aid of frequency inverters, all these engines can stand strong speed- and torque alternations without getting damaged. The frequency inverter ST9100 G1 and ST9100 G3 by Sourcetronic are stocked with an automatism and self-regulating ramps, so the startup procedure is very simple. All you have to do is to press the start button and the frequency inverter starts working. Sophisticated security features, include but are not limited to "PID Feedback-Abnormity" and "Over Voltage Stall", protect the engine even in difficult working environments. In addition to all power connectors, all frequency inverters are equipped with digital and analogue inputs and outputs and an optional RS485 interface. Other measuring devices, for instance a potentiometer (analogue) to set the output frequency, are easily and quickly to connect. Some of many other functions are four-quadrant drive, encoderless field oriented control with freely programmable, linear V / f characteristic line and sensorless vector control.
