Nowadays, horizontal well technology is being
applied to the development of oilfield production capacity more and more. The
horizontal well tractor can effectively solve the problem that the instrument
can not get to the target layer by gravity. However, in actual conditions, Brushless
DC motor (BLDCM) there is a large torque ripple problem, resulting in motor
running is not smooth, vibration and noise is too large, can not meet the
demand. Therefore, propose horizontal well tractor PMSM sine wave drive technology.
The paper discusses the mathematical model of permanent magnet synchronous
motor, analyzes the working principle of space vector pulse width modulation
(SVPWM) technology, and establishes a speed and current double closed-loop
space vector control system of the permanent magnet synchronous motor by using
PSIM simulation software. Simulation results verify the robustness of the
control system, and the torque ripple of the motor is small, in line with the
working conditions of horizontal well tractor.
