Closed-loop control of position, speed and torque. The 60 series AC servo motor eliminates the step-loss problem of open-loop stepper motors and is used in machine tools, medical equipment, printing machinery, food processing equipment, elevators, chemical plant and woodworking machinery.
Position, speed and torque are all controlled in closed loop. Because the drive continuously compares the encoder feedback against the position command, the 60 series AC servo motor does not lose synchronism when the load temporarily exceeds the rated torque. This is the key difference from an open-loop stepper motor: if a stepper is overloaded it skips steps and the machine loses its position reference, whereas the servo detects the error and corrects it.
The 60 series is available in 200 W and 400 W configurations on the same 60 mm mounting flange. Both models share the same frame, encoder socket and mounting dimensions, so they can be used as a direct drop-in replacement on the same machine without re-machining the mounting bracket.

Drives the feed axis of small CNC lathes, milling machines and drilling machines. The 2500 PPR encoder and closed-loop control keep the tool position stable during interrupted cuts where a stepper would lose position.
Used in medical analyzers, sample handling systems and laboratory automation where quiet operation and repeatable positioning matter. The IP65 rating also allows the motor to operate in washdown environments.
Web tension control, registration adjustment and cutting knife positioning on printing presses. The 3000 rpm rated speed matches the throughput of medium-speed presses.
Filling machines, capping machines and packaging conveyors. The stainless-steel-compatible shaft and IP65 sealing allow cleaning without dismounting the motor.
Drives the door operator and leveling mechanism on small elevators. The 200 W model is matched to the typical door load; the 400 W model handles heavier loads on wider doors.
Three-axis or four-axis positioning on woodworking CNC routers, drilling centers and edge banders. The low rotor inertia (0.175 × 10⁻⁴ kg·m²) gives fast acceleration and short positioning time.
RAYDAFON has been designing and manufacturing industrial electric motors, speed reducers and gearboxes since 1990. The 60 series AC servo motor is produced in accordance with the IEC standard, with a range of model selections and configurations that can be matched to specific equipment and machine requirements. OEM and private-label production available. Review our quality assurance, designing and delivery advantages.
The two models share the same 60 mm flange, shaft size (⌀14 mm) and encoder (2500 PPR), but differ in power rating and stator stack length. The 60ST-M00630 is rated 200 W with 0.637 N·m rated torque and 1.16 kg weight. The 60ST-M01330 is rated 400 W with 1.27 N·m rated torque and 1.63 kg weight. Because the mounting flange is identical, one model can be used as a drop-in replacement for the other on the same machine.
A stepper motor runs in open loop: if the load exceeds the torque the motor can produce, it loses steps and the machine loses its position reference. A servo motor runs in closed loop, comparing the encoder signal against the position command continuously. When the load temporarily exceeds the rated torque, the servo detects the position error and corrects it. For applications where a lost step would damage the workpiece or require re-homing, the closed-loop servo is the correct choice.
60 = 60 mm flange. ST = sine wave drive. M = photoelectric encoder feedback. 00630 = rated torque 0.6 N·m and rated speed 3000 rpm. Z1 = magnetic brake option (Z2 = permanent magnet brake). The code is read from left to right and each block identifies one configuration choice.
The 60 series motor uses a standard 15-pin encoder interface and a 4-pin winding interface. It is compatible with servo drives that accept 220 V AC input, 2500 PPR incremental encoder feedback with UVW commutation signals, and the current rating of the chosen motor model (1.2 A for the 200 W version, 2.8 A for the 400 W version). Send us your drive model and we will confirm compatibility.
Yes. The Z1 (magnetic brake) and Z2 (permanent magnet brake) options can be specified in the model code. Custom shaft dimensions, keyway, oil seal and special winding voltage can be quoted on request. Send us the drawing or specification for your application and we will confirm feasibility and lead time.
MOQ depends on whether the order is for a standard configuration or a customized version. Send us your required model, quantity and destination port, and our sales team will confirm MOQ, unit price and production schedule in writing. Standard configurations generally ship faster than customized builds.
