The Leadshine iES series 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.

Leadshine integrated easy servo motors inherit the favored features of both open loop stepper and brushless servo systems. While still keeping costs low similar to stepper systems, fatal drawbacks of open loop stepper systems such as heating, loss of steps, noise are eliminated and significantly improved. Compared with traditional brushless servo systems, Leadshine integrated easy servo motors outperform in high starting & low-speed torque, no hunting, no overshooting, plug-and-play for no tuning in most applications, and almost zero setting time. In addition, the totally integrated design minimizes wiring cables, saves mounting space, and is more reliable to external interference. The serial cable for tuning is on our website at Serial Cable for iST and iES drives
