INVEOR frequency inverter with integrated motion control: Exact positioning without sensor

When we talk about motion control, we mean controlling a movement so that it stops at a defined position. Sensors are usually used for this, which feed back information about the position to the frequency inverter. However, this sensor technology is expensive and makes the system more susceptible to faults. 
Thanks to the patented encoderless control method, Kostal enables positioning applications completely without encoders. The KOSTAL pulse injection method calculates the exact rotor position based on the anisotropy of the motor without an encoder. In other words, it uses the motor itself as a sensor, which functions with high performance in all PM synchronous and synchronous reluctance motors. With the INVEOR MP and MP Modular, you thus receive a positioning function completely sensorless and without any further effort on your part. We call this KOSTAL Integrated Sensorless Position Control.

This video shows the positioning function in a logistics application using a vertical conveyor. A predefined sequence of stopping points is used to always move to the exact position, in this case at different heights. Even after countless repetitions, the position is always precisely controlled.
