Abstract

PURPOSE: To reduce the magnetic resistance between the contacting surfaces of both the core of coil block and the stator and to improve the efficiency of motor by forming a nickel-boron film on either of or both of said surfaces.
CONSTITUTION: Either of or both surfaces of the core 2 of coil block 3 the stator 4 are plated with nickel-boron system film by nonelectrolytic process to reduce the magnetic resistance between the contacting surfaces of both the core 2 and the stator 4. In this way, the magnetic flux produced in the coil 1 is increased, a force that acts on the roror 5 is made greater and the counter electromotive force is also done. Accordingly although the pulse width is reduced, the driving force for the rotor is not dropped, the efficiency of the step motor can substantially be improved.
