Need to get a motion axis moving without guessing? The servo stepper motion control options in front of you span a very wide price range, so the practical question is what you already have on your machine. If you need a complete motor-and-drive package, the Yifeng braked servo and the Kollmorgen pair take different paths. If you only need a motor to add to an existing drive, the Sure Servo SVL-210B is a strong fit. And if your driver already exists and you just need to command it, the SMC05 controller is the low-cost way to do it.
Quick take
- Yifeng: A new AC servo motor with drive amplifier, peak torque 12 N·m, and Modbus support.
- Kollmorgen: A US-built servo motor and AKD drive with a 480V power rating and dust-tight, liquid-protected enclosure.
- Sure Servo: A Japanese AC servo motor rated at 200 VAC, 6.8 A, and 3000 rpm.
- SMC05: A new pulse controller with a 1.8-inch screen, four limit-switch inputs, and 20 motion modes.

Product notes
Brake AC Servo Motor 1KW 4NM NEMA32 Drive Amplifier 220V CW/CCW Z Axis Milling

This Yifeng package combines a 1 kW AC servo motor, a 4 N·m rating, a NEMA32 frame, and a brake for holding a vertical load into one 220V package. It supports position, speed, and torque control modes, and the drive defaults to RS485 with Modbus communication, which is useful if you are building a small CNC controller or an automated machine. Peak torque reaches 12 N·m, and the rated speed is 2500 rpm, so it has enough muscle for a milling Z-axis without needing an external holding brake. The main constraint is the 220V input and the 3-meter cable: you need to plan the cabinet layout around those limits, and any custom voltage or longer cable requires contacting the seller.
Kollmorgen Servo Motor and Drive

Kollmorgen combines the AKMH31C motor and AKD-P00307 drive into one used package with a 480V power rating. The unit is protected against dust and against spraying, dripping, and splashing water, so it is a reasonable choice for a shop floor where coolant or washdown is part of the environment. Because the motor and drive come from the same manufacturer, wiring and setup should be simpler than mixing a motor from one vendor with a drive from another. The limitation is condition: it is a used unit, so the final service life depends on how the previous owner treated the connectors, shaft, and mounting flange. Budget for inspection before you wire it into a critical axis.
Sure Servo Motor SVL-210B

Sure Servo SVL-210B is a 1 kW AC servo motor built in Japan and rated for 200 VAC, 6.8 A, and 3000 rpm. It is described as in good condition for industrial automation, and the compact enclosed housing suits CNC machines, robotics, conveyors, and automated machinery. This is the pick when you already have a drive and need a motor that matches a known power class. The trade-off is the $699 price, which is the highest listed here, and the used condition means the motor should be treated as a serviceable used component rather than a fresh out-of-box purchase.
SMC05 Stepper Servo Motor Pulse Controller with Forward/Reverse Speed Control

At $28.35, the SMC05 is a command device, not a motor: it generates pulse signals for a stepper or servo driver and handles forward/reverse speed control. It runs from 12-24V and offers four outputs, four limit-switch inputs, and three expansion button interfaces, which gives you plenty of room for a small automation cell. The 1.8-inch HD color screen and silicone keypad make parameter changes straightforward, and the 20 motion modes plus remote firmware upgrade widen its range beyond a simple pulse generator. The main limitation is the -5°C to 60°C operating range, so keep it in a conditioned control cabinet if your shop floor gets cold or hot.
Final recommendation by use case
- For a CNC Z-axis with a brake: choose the Yifeng braked AC servo motor and drive amplifier package.
- For an industrial setup where a same-brand motor and drive pair is acceptable: choose the Kollmorgen Servo Motor and Drive.
- For a Japanese AC servo motor to pair with a drive you already own: choose the Sure Servo Motor SVL-210B.
- For the lowest-cost way to command an existing stepper or servo driver: choose the SMC05 Stepper Servo Motor Pulse Controller with Forward/Reverse Speed Control.
