A Leadshine integrated easy servo motor consists of a high torque stepper motor, a rotary encoder, and an integrated DSP-based digital easy servo drive. With the adoption of a high resolution encoder, shaft position of the stepper motor is fed back to the servo drive in real time. The drive can then fully close the position loop, which is the same mechanism as classic brushless servo drives. Therefore, loss of movement synchronization (step loss) in open loop stepper systems is totally eliminated.
