Easy Servo Drives

By adopting high resolution encoders, Leadshine easy servo drives apply servo controls on stepper motors, the same mechanism in those expensive brushless servo drives. In a Leadshine easy servo system, shaft position of the stepper motor is fed back to the servo drive in real time. The easy servo drive can then close the position loop and correct any position errors to eliminate loss of steps commonly seen in open-loop stepper motors.

Leadshine easy servo drives inherit favored features of both open loop stepper and brushless servo drives. When combined with easy servo motors (stepper motors with encoders), Leadshine easy servo systems solve the fatal problem “loss of steps” of open loop step systems. Other drawbacks of open loop stepper systems like high motor & drive heating and noise are also significantly improved. At fractional cost of expensive brushless servo systems, Leadshine easy servo system can upgrade your stepper systems to servo like performance with extra low motor heating, quick response & acceleration, and no torque reservation. In comparison to brushless servo systems, Leadshine easy servo systems outperform in much lower cost, no hunting, no overshooting, almost zero settling time, no tuning for most applications.

Currently, Leadshine offers two series of easy servo drives. The ES-D series easy servo drives which take input voltage of 20-80 DC or max 80AC input to power motors from NEMA 23 to 34. Our ES-DH series easy servo drives can take direct 110 / 120 or 220 / 230 AC input to get rid of power supplies and power motors up to NEMA 42 easy servo motors to provide huge torque for big machines.

Due to combining the features of both brushless servo drives and stepper drives, Leadshine easy servo drives are suitable for both upgrading conventional stepper systems, and replacing brushless servo systems.

While conventional stepper systems are typically adopted for applicatons of 1,000 RPM or below, Leadshine easy servo drives can easily power control systems at least to 2,000 RPM (even higher) with much fast acceleration, much lower heating , higher torque, no loss of steps, smoother motor movement. In comparison to brushless servo drives, Leadshine easy servo drives can power control systems with much high starting & low-speed torque, no hunting, no overshooting, zero setting time, lower costs, and almost "No Tuning".

Leadshine easy servo drives and matching easy servo motors have been successfully implemented by hundred of OEM clients around the world in tens of industries, such as CNC machineries(routers, laser cutters, milling machines, engravers), medical, robotics, semiconductors, electronics, packaging, lab automation ...
