ROTRA Ihr Partner für Automation seit 1987 RO tation + TRA nslation = Automation Stepping motors used with our micro step drivers and controllers enable easy controllable high resolution drives. The typical resolution of 200 steps/rotation is increased 5 to 200 times by the micro stepping. Resulting resolutions of up to 40 000 steps/rotation are possible. Using high lead ball screws with high lead of 40 mm will still give a resolution of 1µm/step. A very important advantage of using stepping motors is the no motion behaviour when in position- a must for applications in the micro- and nanotechnologies. We supply stepping motor systems with servo motor performance.   back to product overview ROTRA Your partner for automation since 1987
