Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
The automation engineers of the 1960s would look with envy at the servo technology in use today. Small, precise, and, above all, electric, they are a reflection of the compactness of the semiconductor ...
Authored by: George Ellis, Chief Engineer, Servo Systems, Kollmorgen, Radford, Va. Key points: Three key measures — accuracy, response, and robust stability — characterize how servosystems perform.
