描述

这六步通勤block uses a 120-degree conduction mode to generate a switching sequence to implement six-step commutation (or trapezoidal commutation) on a three-phase BLDC motor. You can use the switching signals to operate switches and control the stator currents, and therefore, control motor speed and direction of rotation.

块接受大厅序列号或拿出来r position (from a position sensor such as a Hall or a quadrature encoder sensor) and the direction of torque as inputs. It uses the Hall sequence or position input to determine the sector where the rotor is present. The block computes the switching sequence such that it energizes the corresponding phases to maintain the torque angle (angle between rotor d-axis and stator magnetic field) of 90 degrees (with a deviation of 30 degrees).
