STEPPING SYSTEMS STEPPING MOTOR WITH ENCODER
●When open-loop control is not enough
■Stepping systems provide precise positioning with easy control.
■By adding an encoder to a stepping motor, the controller can monitor the actual position directly, closing the feedback loop and improving the safety and reliability.
●Stepping Motor with Encoder: Features
■Safety: Position verification
◆Adding an encoder is an ideal and easy solution for safety-sensitive applications, requiring position verification and position maintenance, such as medical instrumentation.
■Close-loop control with stepper benefit
◆High-end close loop control can be achieved while keeping the advantages of stepping motors: stable stop without hunting, higher torque than DC servo motor at low speed over the same size, eliminating the need of gearboxes.
■Reliability: Stall Detection
◆Device reliability is improved with possible detection and reporting of stalls.
■Accurate Homing
◆Encoder with index pulse option can be used to achieve precise homing.
