鼓风机装置是一个单独的部件，只能使用其自己的订单号进行订购。订购时，表面冷却装置由安装在电机上的INDRAMAT交付，并准备连接。有关鼓风机装置的更多信息，请参阅文件“安装到MDD伺服电机的鼓风机”，文件。编号：9.578.003.4。有两种可能的表面冷却类型：•轴向和•径向表面冷却。轴向表面冷却轴向冷却适用于需要细长形状的应用。图2.9：具有轴向表面冷却径向表面冷却径向冷却的MDD伺服电机的示例适用于需要短结构的应用。图2.10：带径向表面冷却的MDD伺服电机示例2。技术说明•DOK-电机*-MDD******-PRJ1-EN-E1,44•12.96 20单个电机系列的鼓风机选项如图2.11中的表所示。图2.11：鼓风机选项阻挡制动器，用于无齿隙保持伺服轴。当机器断电时，可以为其配备阻挡制动器。专为这些电机开发的闭锁制动器按照闭路原理工作。零电流时，磁力作用在制动电枢盘上。这意味着制动器被锁定并保持在轴之外。使用24V DC时，电场消除磁场，制动器打开。智能数字驱动控制器激活闭锁制动器。这将在所有操作状态下保持接通和断开开关顺序。驱动器中的电流测量值监控制动器的释放。可通过参数选择紧急停机或故障情况下的夹紧力矩，以适应应用：•立即夹紧•速度低于10 rpm后夹紧或•400 ms后夹紧，即使速度大于10 rpm。对于某些电机类型，闭锁制动器具有不同的保持扭矩。对于电机MDD 025和MDD 041，如果电机配备阻挡制动器，则标称扭矩MdN会有所下降。有关说明，请参见相应电机系列的“技术数据”一节。用于表面冷却的电机型鼓风机轴向-径向MDD 021-MDD 025-MDD 041-MDD 065+1）-MDD 071+1）+1）MDD 090++1）MDD 093++MDD 112++MDD 115++-不可用+可用1）不适用于电机长度“A”

The blower unit represents a separate component and can only be ordered with the use of its own order number. When ordered, the surface-cooling unit is delivered by INDRAMAT mounted to the motors and ready to connect. Additional information about the blower units can be found in the documentation entitled "Blowers for mounting to MDD servo motors", doc. no.: 9.578.003.4. Two possible types of surface cooling are available: • axial and • radial surface cooling. Axial surface cooling Axial cooling is suited for those applications that need a slender form. Fig. 2.9: An example of an MDD servo motor with axial surface cooling Radial surface cooling Radial cooling is suited for those applications that need a short construction.

Technical Explanations • DOK-MOTOR*-MDD********-PRJ1-EN-E1,44 • 12.96 20 The blower options for the individual motor series are listed in the table in Figure 2.11. Fig. 2.11: Blower options Blocking brake For a backlash-free holding of the servo axes when the machine is powered off, it is possible to equip them with a blocking brake. The blocking brake, especially developed for these motors, works along the closed-circuit principle. At zero current, a magnetic force acts on the brake armature disc. This means that the brake is locked and holding off the axis. With the application of 24V DC, the electrical field cancels the permanent magnetic field and the brake opens. The intelligent digital drive controller activates the blocking brake. This maintains the on and off switching sequence in all operating states. Current measurements in the drive monitor the release of the brake. The moment of clamping for an E-stop or fault situation can be selected via parameters to suit the application: • immediate clamping • clamping after speeds falls below 10 rpm or • clamping after 400 ms, even with speeds greater than 10 rpm. With some motor types, the blocking brake is available with varying holding torques. With motors MDD 025 and MDD 041, the nominal torque MdN drops somewhat if the motor is equipped with a blocking brake. Notes on this can be found in the section "Technical Data" of the respective motor series.
