| 摘要 |
The present invention concerns an electronically commutated motor, in which for commutation, the output signals of a number of correspondingly arranged Hall sensors are initially evaluated to generate a multiple-figure digital code and in which, after startup of the motor, only one figure of the code is still generated by evaluation of the output signal of a single Hall sensor, while the remaining figures of the digital code are taken from a table stored in an electronic logic component as bit pattern or determined by means of a corresponding algorithm. The advantage of this expedient is that commutation no longer depends on the position-tolerance arrangement of several Hall sensors, but occurs at the best possible time.
