1. Quick response, no hunting

For the case of conventional servo motor systems, there is a considerable delay

between the commanding input signals and the resultant motion because of the

constant monitor of the current position, necessitating a waiting time until it settles,

called settle time.

Since the MEZ servo is a stepper motor based system, it operates in synchronism with

command pulses and has no hunting problem. When it stops, its position is completely

stable and does not fluctuate. It is a great feature of the MEZ when rapid motions with

a short distance are required and it is ideal for applications such as bonding and vision

systems in which hunting would be a problem.

2. High torque at starting and low speed, high inertial loads

Since the MEZ servo system is a stepper motor based system, so it has the advantages of

high stiffness at standstill, high torque at starting and low speed, eliminating gear

box. The MEZ adopts sophisticated control algorithms to take advantage of high-torque

capability, providing direct-drive of high inertia loads such as flywheels and belt drives.

These load inertials may be as large as 100 times the motor inertia while still providing

smooth positioning control. Conventional servo systems typically cannot exceed a 10:1

inertial mismatch.

3. Plug and play, no tuning for most of applications

Unlike a servo system which usually needs the engineer to spend a long time to learn how to

use tuning tools and tune the gains for a satisfying performance, the MEZ series servo is

ready for operation within a very short period of time. Set the microstep resolution and

operating current, then the system is ready and offers high performance aCPRoaching to a

fine tuned servo. Save time and save cost.

Typical Applications

Due to combining the features of both brushless servo systems and stepper systems, MotionKing MEZ servo systems are ideal

solutions for both upgrading conventional stepper systems, and replacing many brushless servo systems.

While conventional stepper systems are typically adopted for applications of 1,000 RPM or below, MotionKing MEZ servo systems

can easily upgrade your motion control systems to the speed of 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 systems, MotionKing MEZ

servo systems can power control systems with much high starting & low-speed torque, no hunting, no overshooting, zero setting

time, lower costs, and no tuning for most of applications.

MotionKing MEZ servo systems have been successfully implemented by hundred of OEM clients in the world in tens of industries

such as CNC machinery, electronics, CMM measuring / inspection, medical, lab automation, semiconductor, scientific instruments,

textile, etc.
