►无刷电机技术无易损件(碳刷,换向器,磁场线圈)►我们的原始紧凑控制器长寿命,免维护无刷电机提供了一个显著延长的产品生命周期,消除了电枢烧毁等麻烦,层短或换向器磨损,即使在恶劣的工作环境。此外,不需要更换碳刷。强大的扭矩。更多的权力。最大紧固扭矩为305Nm为18V WR18DBDL2和285Nm为14.4V WR14DBDL2。与我们的传统型号(WR18DBDL, WR14DBDL)相比,扭矩分别增加了55Nm (18V)和50Nm (14.4V)。整体长度为145毫米,比我们的传统型号(WR18DBDL/WR14DBDL)短23毫米。高效、长运行时间(约)磨擦环将插座固定在砧上,使安装销钉和o形环更容易,以安全地将插座锁定到位。 Note : It is possible to temporality hold the socket in place with the friction ring, but be sure to insert the pin and attach the O-ring before use. If the power tools is used while the socket is temporarily held in place, the socket may fall off and cause an injury. Newly Designed Airflow System for Optimal Cooling Efficiency The rear fan efficiently cools down the motor and hammer case for more durability.
