Abstract Most of the existing (BLDCM) brushless dc motor drive systems are designed with the traditional drive scheme for long-time operation. For short-time and heavy-duty applications, there are problems of energy consumption, large volume, heavyweight and high-cost. In this paper, a new short-time high-overload BLDCM drive system based on "electronic flywheel" and time-division switching control is proposed, which includes three core contents: a crushing chamber based on combined cutter head, an energy storage device based on an "electronic flywheel" and high overload factor BLDC using a new calculation method of capacitance and a speed control system based on time-division switching control of the speed loop and the current loop. To prove the effectiveness of the proposed scheme, a kitchen garbage processor is developed and tested. The results show that the "electronic flywheel" energy storage driving device designed in this paper is able to provide most of the energy required in the heavy-duty driving process. The designed time-division switching control scheme can well meet the control requirements for the short-time heavy load drive of the kitchen waste processor. Compared with the traditional long-time rated load drive scheme, the proposed system has the advantages of energy-saving, small volume, lightweight and low-cost.

基于电子飞轮和时分切换控制的新型短时高过载BLDC驱动系统

摘要 现有的(BLDCM)无刷直流电机驱动系统大多采用传统的驱动方案设计,以实现长时间运行。对于短时重载应用,存在能耗大、体积大、重量大、成本高等问题。本文提出了一种基于“电子飞轮”和时分切换控制的新型短时高过载BLDCM驱动系统,它包括三个核心内容:基于组合刀盘的破碎腔,基于储能装置的储能装置。在“电子飞轮”和高过载系数 BLDC 上,使用新的电容计算方法和基于速度环和电流环的时分切换控制的速度控制系统。为了证明提议方案的有效性,开发并测试了厨房垃圾处理器。结果表明,本文设计的“电子飞轮”储能驱动装置能够提供重载驱动过程所需的大部分能量。设计的分时切换控制方案可以很好地满足餐厨垃圾处理器短时重载驱动的控制要求。与传统的长时间额定负载驱动方案相比,所提出的系统具有节能、体积小、重量轻、成本低的优点。设计的分时切换控制方案可以很好地满足餐厨垃圾处理器短时重载驱动的控制要求。与传统的长时间额定负载驱动方案相比,所提出的系统具有节能、体积小、重量轻、成本低的优点。设计的分时切换控制方案可以很好地满足餐厨垃圾处理器短时重载驱动的控制要求。与传统的长时间额定负载驱动方案相比,所提出的系统具有节能、体积小、重量轻、成本低的优点。
