SAFT-169-PAC 输入/输出模块

SAFT-169-PAC电机的选型主要根据电机的类型、结构型式、容量、额定电压和额定转速等因素而定。

SAFT-169-PAC电机选型的基本原则是：

（1）根据生产机械调速要求选择电机类型。

（2）在工作过程中应充分利用电机的容量。

（3）根据工作环境选择电机的结构型式。

需要强调的是，在满足设计要求的条件下，应优先采用结构简单、价格便宜、维修方便的三相交流异步电动机。

正确选择电机容量是电机选型的关键问题。电机容量的计算方法有两种，一种是解析计算法，另一种是统计类比法。分析计算方法是根据机械功率估算电机的工作状态，预先选择一台电机，然后根据电机的实际负载制作负载图，根据负载图检查温升，确定预选电机是否合适，不合适时再重新选择， 直到电机合适为止。

The selection of SAFT-169-PAC motor is mainly based on the type of motor, structural type, capacity, rated voltage and rated speed and other factors.

The basic principles of SAFT-169-PAC motor selection are:

(1) Select the type of motor according to the speed regulation requirements of the production machinery.

(2) The capacity of the motor should be fully utilized during the working process.

(3) Select the structure type of the motor according to the working environment.

It should be emphasized that under the condition of meeting the design requirements, the three-phase AC asynchronous motor with simple structure, cheap price and convenient maintenance should be given priority.

Correct selection of motor capacity is the key problem of motor selection. There are two kinds of calculation methods for motor capacity, one is analytical calculation method, and the other is statistical analogy method. The method of analysis and calculation is to estimate the working state of the motor according to the mechanical power, pre-select a motor, and then make a load diagram according to the actual load of the motor, check the temperature rise according to the load diagram, and determine whether the pre-selected motor is suitable, and then re-select when it is inappropriate, until the motor is suitable.
