本节概述了环境条件、电机的机械和电气特性以及电机反馈的说明。2.5节提供了有关转矩-速度特性曲线的重要细节，这些曲线依次在3.2节、4.2节和11.2节中描述了每种类型的电机。2.1. 环境条件安装高程和环境温度“技术数据”一节中概述的输出数据是在以下条件下获得的：环境温度：0°至+45°C安装高程：海拔0至1000米如果条件偏离这些值，则输出数据将减少，如图2.1所示。如果同时出现较高的环境温度和较高的安装高程，则必须乘以荷载系数fT和fH。图2.1：在较高环境温度和较高安装高度下的负载能力保护类别MDD电机由其外壳和盖子进行保护，其在结构和设计上符合DIN 40050中的指南，并防止电机部件移动或带电时接触高压（接触防护装置），•外部物体的渗透•和水的渗透。保护类别由缩写IP（国际保护）和保护类型的两个数字规定，例如IP 40。一个数字表示防止外部物体接触和穿透的防护程度（见图2.2）。二个数字表示针对水的破坏性渗透提供的保护程度（见图2.3）。图2.4描述了适用于MDD电机的保护类别范围。1 0.6 0.8 40 45 50 55环境温度in°C荷载系数fT 1 0.6 0.8 1000 2000 3000 4000海平面以上安装标高荷载系数fH 5000 DGMDDUMTEM较高环境温度下的荷载较高安装标高下的荷载

This section outlines a description of the ambient conditions, the mechanical and electrical features of the motor as well as the motor feedback. Section 2.5 offers important details about the torque-speed characteristics curves which are, in turn, depicted for each type of motor in sections 3.2, 4.2 and through to 11.2. 2.1. Ambient Conditions Installation elevation and ambient temperatures The output data outlined in the section "Technical Data" are achieved under the following conditions: Ambient temperature: 0° to + 45 °C Installation elevation: 0 to 1000 meters above sea level If the conditions deviate from the values, then the output data will decrease as depicted in the diagrams shown in Figure 2.1. If higher ambient temperatures and higher installation elevations occur simultaneously, then the load factors fT and fH must be multiplied. Fig. 2.1: Load capabilities at higher ambient temperatures and higher installation elevations Protection Category The MDD motors are protected by their housing and covers which in construction and design adhere to the guidelines found in DIN 40050 and protect • against contact to high voltage with motor parts either moving or alive (contact guards), • the penetration by extrinsic objects • and the penetration of water. The protection categories are laid down by the abbreviation IP (International Protection) and two numbers for the type of protection, for example, IP 40. The first number represents the degree of protection afforded against contact and penetration by extrinsic objects (see Figure 2.2).The second number represents the degree of protection afforded against the damaging penetration by water (see Figure 2.3). Figure 2.4 depicts the range of the protection categories as applicable to MDD motors. 1 0.6 0.8 40 45 50 55 Ambient temperature in °C Load factor fT 1 0.6 0.8 1000 2000 3000 4000 Installation elevation above sea level Load factor fH 5000 DGMDDUMTEMP Loads at higher ambient temperatures Loads at higher installation elevations
