Sensorless drives for highest energy efficiency at reduced costs in production and maintenance
- sensorless control for drives of highest reliability
- lower costs in production and maintenance
- with reluctance motors: no need for rare-earth magnets, no magnetic field in de-energized state – advantageous for special functions, e.g. magnetic bearings
- top energy efficiency (IE4)
- without mechanical encoders – e.g. rotor position sensors or tacho generators
- highly dynamic speed and torque controls
- “jerk-free” acceleration and braking, from a standstill and under variable load
- no permanent angular error – not even with overload or low speed
- without rotor position sensors: reduction of installation space, omission of sensor cables and plug connections
- during installation, maintenance or repair: no need to match the position sensor and the magnets’ position in the motor; possible wiring and maintenance errors in connecting sensor and controller excluded
- suitable for safety-critical applications
- for existing system designs: suitable as redundant check on position and speed
- 30 years experience in the design of sensorless controlled synchronous motors
- based on proven INFORM® control system with tens of thousands of systems on the market - e.g. in medical technology and aviation
Innovation level:
- for the first time energy-saving, highly efficient synchronous drives at low system costs
- already successfully used in various series applications, for example in medical technology and aviation
Target groups and applications:
- eMobiliy, automotive
- aerospace
- medical technology
- machine tools, production machines, automation
- construction machinery and lifting equipment
- emergency units of various sorts
- consumer goods
- from a few watts to the megawatt range
- cost-effective replacement for asynchronous motors
- drives with highest energy efficiency (IE4) and reliability even under difficult environmental conditions – e.g. no freezing nor corrosion of sensors
