| 摘要 |
The invention concerns a motor with electronic switching, such as in particular a collector-free motor, comprising a device powering said motor, from an AC voltage system, consisting in particular of a rectifier bridge connected to the AC voltage system, a capacitive filter connected in output of the rectifier bridge and consisting of at least a capacitor, delivering a so-called input voltage V>e< of a circuit controlling the motor for injecting a current i in the stator parts of the motor, said motor, having, in operation, an electromotive force. The invention is characterised in that the control for establishing current i has a phase advance relative to the electromotive force whereof the value, called phase advance angle is variable according to the input voltage V>e<. |
