直流无刷电动机 Brushless DC electric motor

(重定向自Brushless Motor)
BLDC (电脑风扇)
BLDC的工作原理 (三组线圈)
Rotor de una pequeña máquina de corriente directa de 12 V, con imanes permanentes, de dos polos, cinco devanados, cinco delgas y dos escobillas.
BLDC-Motor mit 3x3 Statorspulen in der Mitte, herausgebrochen aus einer Platine. Die Magnetisierung des glockenförmigen Rotors mit seinen 6 Polen ist im oberen Bildteil schwarz hervorgehoben.

直流无刷电动机Brushless DC Motor)是没有电刷和换向器的直流电动机。

结构上是交流同步马达,利用电力电子技术(逆变器)输入交流信号到马达。但这些交流信号不是正弦波,只是双向的直流电,波形没有限制。

较简单的结构是有一枚永久磁铁及两组(四个)线圈,两组线圈轮流开关。永久磁铁是转子,线圈是定子。当磁铁与线圈成一直线的时候,断开该组线圈,启动下一组线圈。

与传统有刷式直流电动机相比,无刷式较为安全和可靠。碳刷长期使用有碳粉,高温环境下,碳粉可能会爆炸。因此,需要定期清理,同时保养成本较高。

Brushless DC electric motor 直流无刷电动机

(重定向自Brushless Motor)
The motor from a 3.5
Schematic for delta and wye winding styles. (This image does not illustrate the motor's inductive and generator-like properties)
The four poles on the stator of a two-phase brushless motor. This is part of a computer cooling fan; the rotor has been removed.
A microprocessor-controlled BLDC motor powering a micro radio-controlled airplane.  This external rotor motor weighs 5 g and consumes approximately 11 W.

Brushless DC electric motor (BLDC motors, BL motors) also known as electronically commutated motors (ECMs, EC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. In this context, AC, alternating current, does not imply a sinusoidal waveform, but rather a bi-directional current with no restriction on waveform. Additional sensors and electronics control the inverter output amplitude and waveform (and therefore percent of DC bus usage/efficiency) and frequency (i.e. rotor speed).
