摘　　要：在电机电控的学习中,尝试探讨一种新颖的学习思路,对常见电控电路,运用逻辑电路设计,用真值表对电路的控制要求进行逻辑抽象,再根据真值表写出逻辑表达式,并对表达式按逻辑代数法或卡诺图法进行化简,最后按最简表达式画出要实现的电控电路。实践证明,通过逻辑设计实现的控制电路,电路直观简洁、功能完善可靠。This paper attempts to explore a kind of new learning idea in motor control study. For common electronic control circuit, finally draw the electrical control circuit by the minimalist expression and logic circuit design, and abstracting logic circuit control with a truth table, and writing logic expressions according to the truth table, and simplify the expressions by logical algebra and Karnaugh map. Practice has proved that through the logical design implementation of control circuit, the circuit is intuitively simple, functional and reliable.
