Composite Rotor Of A Step Motor And Method For Producing The Same

A method for producing a composite rotor of a step motor comprising the steps of:

• forming:
• integrally forming a positioning protrusion on a positioning member;
• and
• assembling:
• inserting the positioning member into a first magnetic conductive member embedded with a first magnet in such a manner that the first magnetic conductive member abuts against the positioning protrusion of the positioning member, and then the positioning member will be inserted into a second magnet in such a manner that the second magnet abuts against the first magnet and the first magnetic conductive member, after that, a second magnetic conductive member embedded with a third magnet will be mounted on the positioning member in such a manner that the third magnet and the second magnetic conductive member both abut against the second magnet.
