Integrated Easy Servo Motors
(Integrated Closed-Loop Steppers with motor + encoder + drive)
At very compact size, a Leadshine iES series integrated easy servo combines a stepper motor, a 1000-line encoder, and a high performance DSP-based easy servo drive. With real-time motor shaft position updated by the encoder, the servo drive compensates lose of movement synchronization due to sudden velocity or load condition changes. Therefore, position loop between the drive and motor are fully closed, the same mechanism implemented in traditional brushless servo systems.
The iES series easy servo motors outperform open-loop stepper systems in no stall, no lose of steps, much lower motor heating, no obvious motor resonance area, much lower motor heating, 100% implementation of available torque, much smother motor movement...
The iES series easy servo motors also have advantages over brushless servo system in much higher low to middle speed torque, lower costs, quicker response, no overshooting, no hunting, zero settling time, and no tuning.
