A hybrid stepper motor combines the best features of a standard variable reluctance step motor and a permanent magnet step motor. This hybrid of the two types of stepper motors allows the hybrid step motor to generate a great amount of power despite its small size. The hybrid stepper motor is multi-toothed like the variable resistance motor but contains permanent magnets like a permanent magnet motor. In effect, the hybrid stepper is sort of like a permanent magnet stepper motor "plus". A variable stepper motor relies on those teeth to move the motor accurately, while the permanent magnet stepper relies on the magnets. The motor wire is made of pure copper enameled wire wound through wire technology.The copper wire is evenly arranged,the temperature rise of the motor is lower,and the deformation and noise will not occur during long-term transportation.silicon steel rotor the bearing is made of international silicon steel material and imported German technology the surface is coated with imported rotor glue to prevent oxidation of silicon steel and reduce the surface burr after grinding.compared with the motor in the same line,the output is more stable the noise is lower Specifications:- ?
