margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"> 采用直接传动式喷水织机,电动机通过皮带、皮带轮直接将动力传递给主轴,因此在电动机与主轴之间的传动链上不存在离合器,机构较简单,且当织机以任何方式停机时,电动机均断电停止转动,避免了电动机的空转。但是为了缩短启、制动时间,必须配备较大功率的电动机,以提供足够的启制动力矩,如LW603—230所配电动机:平纹2.6kW,多臂317kW;ZW405—230所配电动机:平纹</span></p><p style="text-align: center;

padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"> 直接式传动系统所用的电动机是与织机直接联动的,为提高电动机的启动转矩,启动时可预先从电动机绕组星形和三角形二种接法中选择三角形接法,待启动后正常运转时再转回星形接法。但采用该传动方式,由于织机的启、制动相当频繁,启动时电流大,致使效率下降;另外在制动时,电动机转子和小皮带轮一起刹停,增加了制动的负荷。</span></p><p style="max-inline-size: 100%;
