| 摘要 |
The invention concerns an electric motor with electronic switch, such as a motor without collector and a device powering said motor from alternating voltage source network with maximum peak (Emax), consisting of: a rectifier bridge (2) connected to the alternating voltage network; a capacitive filter connected in output of the rectifier bridge, consisting of at least a capacitor of capacitance C; a voltage inverter (4) connected to the terminals of the capacitive filter (C), and comprising at least a static switch (T1, T2, T3; T4), each switch being capable of supporting a maximum voltage VCE0 between its terminals; a motor with electronic switch of nominal power P, and having a phase inductance of value L. The invention is characterised in that the capacitance C of the capacitive filter is greater than formula (I) and less than formula (II). |
