摘　　要：串励电动机的励磁绕组与电枢绕组串联,常用的电磁制动方法是切换两绕组的连接端,电路复杂。依据电动机实现电磁制动的原理,提出一种只需在电路中增设一个功率开关管,制动时电枢并联支路的停车制动方法;分析了制动电路的特点、设定电路参数,并通过应用进行了验证。The excitation winding and armature winding is contacted in series- excited motor. The common electromagnetic braking method for the series- excited motor is implemented through switching the end connections of the two windings,but the switching circuit is complex. Addressing this problem,a parking brake method for the series- excited motor according to the principle of the motor's electromagnetic brake was proposed. The method only needs to add a power switch tube in the circuit and parallel a branch with the armature winding when braking. Taking the series- excited motor system using the proposed parking brake method as an example,the characteristic of the braking circuit was analyzed,the parameters of the braking circuit were set and the proposed parking brake method is verified correct.
