A drive system with brnshless DC motor for bore-hole pump for oil industry is presented in the paper. The motor with pump forms a set placed into a hole of up to 2 km deep. Construction of the set is described in the paper. Control system of the drive consists from the inverter controller and process controller. Full control of oil production is provided. Sensorless control of the motor is required to avoid long signal cable. An algorithms for sensorless switching of motor phases based on a back emf is presented Correction of motor and measurement asymmetry is described. Simulation and experimental results are presented.
