Control system for motor speed regulation
The invention provides a control system for motor speed regulation. The control system comprises a control module, a driving module and a motor body, the driving module comprises a first driving end,a second driving end, a third driving end, a plurality of upper bridge control ends and a plurality of lower bridge control ends corresponding to the upper bridge control ends; the upper bridge control end and the lower bridge control end are connected with the control module, the first driving end is connected with a U-phase line of the motor body, the second driving end is connected with a V-phase line of the motor body, and the third driving end is connected with a W-phase line of the motor body. When one of the upper bridge control ends outputs a modulation waveform to adjust the speed ofthe motor body, the control module is used for controlling the lower bridge control end corresponding to the upper bridge control end to output a complementary waveform complementary with the modulation waveform, and the control module is also used for controlling one of the other lower bridge control ends to output a high level. According to the control system for the motor speed regulation provided by the invention, the phenomenon that the motor body is out of control for a short time is avoided, the brake bar operates smoothly, and the door is opened and closed in place stably.
本发明提供一种电机调速的控制系统，包括控制模块、驱动模块及电机本体；驱动模块包括第一驱动端、第二驱动端、第三驱动端、多个上桥控制端及与所述多个上桥控制端对应的多个下桥控制端；上桥控制端及下桥控制端均连接控制模块，第一驱动端连接电机本体的U相线，第二驱动端连接电机本体的V相线，第三驱动端连接电机本体的W相线；当其中一个上桥控制端输出调制波形对电机本体进行调速时，控制模块用于控制与上桥控制端对应的下桥控制端输出与调制波形互补的互补波形，且控制模块还用于控制其余下桥控制端中的一个输出高电平。本发明提供的电机调速的控制系统，避免了电机本体出现短暂速度失控的现象，闸杆运行流畅，且开关门到位平稳。
