Dual lane control of a permanent magnet brushless motor using non-trapezoidal commutation control |
摘要 |
A motor control system and method implements non-trapezoidal motor control and meets established "fail passive" regulatory guidelines. In particular, a system and method of controlling a multi-phase brushless motor that includes a multi-pole permanent magnet rotor, and an individual, electrically isolated stator winding associated with each phase that includes a first terminal and a second terminal. A motor command is supplied to a motor control. The motor control is configured such that the first terminal of each stator winding is selectively coupled to a power source at a first duty cycle, and the second terminal of each stator winding is selectively coupled to a power source asynchronously with the first terminal of each stator winding at a second duty cycle.
