PU516 3BSE013064R1 应查看步进电机的绝缘，zui好在接线之前完成对电机的单体调试查看，当电机契合现行标准要求时，再接外部线。一般低压电机的绝缘电阻要求大于0.5MΩ，摇表使用500V。

但是，直流电机的励磁绕组和电枢绕组如果彼此直接反，就可能使电机电枢带电时，励磁绕组不带电而失磁，使电机空载时可能飞车，重载时烧坏转子。因而，直流电机的电枢绕组和励磁绕组的外部接线肯定不可彼此直接错。

电机的外接线。电机接外部电线之前，应先查看端盖内的各个绕组引出端是否有松动现象，当内部引出线的压接螺丝上紧之后，才干按要求的接线办法连接短路片，并压接外部线。

电机装置和接线结束之后，电机试运转前，工程师在此建议客户这时应主要进行下列查看：

（1）土建清扫整理结束；

（2）电机单体装置、查看结束；

（3）电机操控回路等二次电路的调试结束，工作正常；

（4）搬动电机转子时，转动灵敏，无碰卡现象；

（5）电机主回路体系的悉数接线固定结实，无任何松动；

（6）其他附属体系齐全合格。

PU516 3BSE013064R1 should check the insulation of the stepper motor, it is best to complete the single commissioning of the motor before wiring, when the motor meets the current standard requirements, then connect the external line. Generally, the insulation resistance of low-voltage motors is required to be greater than 0.5MΩ, and the table uses 500V.

However, if the field winding and armature winding of the DC motor are directly opposite each other, it may make the motor armature charged, the field winding is not charged and magnetization is lost, so that the motor may run fast when it is unloaded, and the rotor is burned out when it is overloaded. Therefore, the external wiring of the armature winding and the excitation winding of the DC motor must not be directly wrong with each other.

External wiring of the motor. Before the motor is connected to the external wire, it is necessary to check whether the leading end of each winding in the end cover is loose. When the crimping screw of the internal lead wire is tightened, the short circuit sheet can be connected according to the required wiring method and the external wire is crimped.

After the motor installation and wiring is completed, before the motor test run, the engineer hereby recommends that the customer should mainly carry out the following review at this time:

(1) Completion of civil cleaning;

(2) Single motor device, view end;

(3) The debugging of the secondary circuit such as the motor control circuit is completed and the operation is normal;

(4) When moving the motor rotor, the rotation is sensitive and there is no bumping phenomenon;

(5) All the wiring of the main circuit system of the motor is fixed and strong, without any loosening;

(6) Other subsidiary systems are complete and qualified.
