无叶电机 方案,可识别电机异常,过载,输入电源异常等,并在故障发生后进行相应的保护。如果可能,还可在异常恢复后,重新恢复工作。同时,还可增加红外遥控,数码管显示,液晶显示等人机交互界面。可实现自然风,定时功能,预约,智能控制等功能。
主要应用的无叶风扇参数:
输入电压:220AC
电机:310VDC,8200RPM,45W、直流无刷无传感器控制方案
为精确控制电机转速,通常需要在直流无刷电机上增加位置传感器(例如:霍尔传感器)。控制器根据传感的信号,进行相应的控制

We propose a position sensorless control scheme for a four-switch, three-phase brushless DC motor drive, based on
the zero crossing point detection of phase back-EMF voltages using newly defined error functions (EFs). The commutation instants
