2-Phase Stepper Servo System MotionKing (China) Motor Industry Co., Ltd. www.MotionKing.com M K 1 5 0 2 , R e v . 0 2 - 2 - By adopting high resolution encoders, MotionKing MEZ servo pr oducts apply servo controls on high torque stepper motors. Those products combine advantages of brushless servo systems and conventional stepper systems. Compare to traditional Steppers 1. Closed-loop, eliminates loss of synchronization In open-loop stepper systems, potential loss of motor movement synchronization limits their adoption for many applications. Engineers are forced to reserve 50% of available stepper motor torque to avoid possible loss of steps or stall. With the adoption of high resolution encoders to feedback real time motor shaft positions, MotionKing MEZ series servo drives close the position loops between servo drives and driven motors. That will keep motor movement synchronized all the time, and allow 100% of available torque. 2. No torque resovation for broader operating range Due to closed loop control and adoption of advanced control algorithm, the MEZ series servo systems can always implement 100% torque of the motor, and do not need the huge 50% torque reservation in normal open-loop stepper systems. This feature significantly improves system high speed performance. While open-loop stepper systems are typically adopted in applications under 1,000 rpm, the MEZ series servo systems are ideal for many applications up to 2,000 RPM, sometimes even to 3,000 RPM! 3. Quicker Response, Higher Acceleration Also due to closed loop control and adoption of advanced control algorithm, the MEZ series servo systems can always implement 100% torque of the motor. This feature significantly improves system response or acceleration performance, usually up to 30% quicker or higher acceleration than a same size and holding torque conventional steppers. 4. Extra low motor heating In open-loop stepper systems, output current to the stepper motor from the step driver is constant. No matter what load condition is and how much current is needed, the stepper drive will always output a constant current. Since the MEZ servo runs in closed-loop, the MEZ drives only put as much current into the motor as required to drive the motor to the target. Motor heat is 20 to 40 oC lower compare to a conventional stepper drive which runs at full current most of the time. Less power consumption and longer motor lifetime can be achieved, reducing using and maintenance cost. Compare to Servos

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 syst ems 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 typica lly adopted for applications of 1,000 RPM or below, MotionKing MEZ servo systems can easily upgrade your motion control system s 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 starti ng & 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.
