Abstract


The ZT95 type speed-adjustment DC motor described in this text is a kind of DC motor has the domestic leading level of technology and uses advanced technology introduced from abroad. It has high speed regulation ratio(generally all about 2.5～4 times),very high multiple overload(generally about 2.5times),so this type of motor is the most difficult to design and manufacture. However, the speed regulation ratio of the main product Z710 series motor (armature diameter isφ990 mm) developed in our factory can not higher than 2.5 times, for the Z900 series (armature diameter isφ1240 mm), the speed regulation ratio can not higher than 2 times; The speed regulation ration for ZT95 speed-adjustment DC motor used in the coiling machine of steel plant, can reach to 3~4 times. Because this series of motor uses special design method in electromagnetism, commutate, structure, airiness, cooling, etc, we can choose higher developing parameter.This text gives a detailed introduction about the point of electromagnetism and mechanism structure design for ZT95 speed-adjustment DC motor used in steel factory; Also, we introduces below information: the analysis and verification for the selection and uses of unidirectional binding tape, the insulation structure and characteristics of the motor, the selection and calculation for the rotor coil with special structure, exceptional method for heat elimination, peculiar motor manufacture technics, comparison analysis about experimental and design data, etc. Meanwhile, combined with the current situation, we do analysis about market prospect in the future.
