Dimension (unipolar windings)


※ The above drawings are for dual shaft stepping motor, while single shaft without part            

※ Costomized features are available, such as additional eccentric gear box, power off brake, encoder.

※ Spigot installation with front cover is a must when set up the motor, tolerance fiding should be taken into account, to secure the concentricity of output shaft and motor output.
