PU516 3BSE013064R1 应查看步进电机的绝缘，最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。

PU516 3BSE013064R1 should check the insulation of the stepper motor. It is best to complete the individual debugging and inspection of the motor before wiring. When the motor meets the current standard requirements, external wires should be connected. The insulation resistance of general low-voltage motors is required to be greater than 0.5M Ω, and the megger should use 500V. However, if the excitation winding and armature winding of a DC motor are directly opposite to each other, it may cause the excitation winding to lose excitation when the motor armature is energized, which may cause the motor to spin when unloaded and burn out the rotor when overloaded. Therefore, the external wiring of the armature winding and excitation winding of a DC motor must not be directly wrong with each other. External wiring of the motor. Before connecting the motor to external wires, it is necessary to check whether the outgoing terminals of each winding inside the end cover are loose. Only after the crimping screws of the internal outgoing wires are tightened can the short circuit strips be connected according to the required wiring method and the external wires be crimped
