Project description: As main effect of recently carried grants (in cooperation with Institute of Control and Industrial Electronics from Warsaw University of Technology), a new series of sensorless vector frequency converters was worked out (up to 160 kW rated motor power). As a continuation of R&D implementing an extended power range product line (up to 315 kW rated motor power) is planned. Proposed frequency converters can be used for smooth and precision control of rotational speed of AC motors (typical, 3-phase squirrel cage induction machines). These converters was designed as general purpose equipment with easy application in new and refurbished systems (inverters are powered from typical AC-mains: 3x400 V 50 Hz). Worked out frequency converters gives as results for example rapid energy savings, vibrations limiting, noise level limiting, machine overhaul life elongating (less wearing of transmission gears, clutches etc.). Project innovativeness: Worked out vector frequency converters are based on previous, standard-line devices. In proposed new vector inverters innovative control method was used (DTC -Direct Torque Control) to direct control of motor generated torque. This method makes possible to accurately control of motor torque (also for zero velocity conditions with stopped motor shaft) and maintain declared drive parameters also without an speed/position (encoder) installed. For the sake of using innovative control methods use of mechanical speed/position sensor isn’t necessary. Proposed frequency converters are totally domestic products. These are competitive products for worlds potentates as ABB, Vacon, Siemens, Danfoss, Eurotherm Drives etc. Proposed electrical drives (frequency converters) don’t have functional equivalents on national market in proposed power range.

The system includes a sensor and evaluation software that captures 3D data that can be used to derive a quality claim objectively based on the measured values.

Linux driver and a USB 2.0 or USB 3.0 camera provide an inexpensive application for kiosk systems, microscopy, or the ITS sector.

Inserts fit into the company's standard metal, EMC (high shielding), HPR (external power) or Han-INOX (stainless steel) housings.

Enhancements include built-in debugging tools for VBScript, support for HTML 5 screens and animations, and Russian and Simplified Chinese languages.
