 <description><![CDATA[刚才去细细研究了一下，验证了版主的准确性，也特来分享！&nbsp;&nbsp;

直接上结果了
一般来说制动电阻电流I=P(即你的电机是1.5千瓦，你的电流就是1.5安)&nbsp;&nbsp;电阻阻值=V(直流母线电压，一般取700)/I(上面的制动电流值)，功率=电机功率*Kc，Kc根据实际情况定，电梯取10-15%，离心机取5%，下放超过100米吊车取20-4 ..]]></description>

 <description><![CDATA[[quote]引用第1楼guochunyi于2012-08-08 21:22发表的&#160;&#160;:
根据经验和直流母线电压计算，应选用450欧姆，210W左右的刹车电阻。
