Sensorless drive for gear pump

Sensorless drive for gear pump


Project Description

Brushless DC sensorless drive for small power applications (less than 100 W) such as a gear pump employed in sterile fluids treatment. Full custom design, coupled with finite element simulation of the motor. Employment of sensorless control algorithm based on the Back-EMF measurement. The use of discrete component design allows to reduce costs and to guarantee robust construction.
