Choosing between a single-axis servo motor and a full servo drive kit is a common fork in the road for motion control builds. You can buy a dedicated motor package, or spend less on a package that includes a controller, spindle, PLC, and gearbox. The decision comes down to what you need for holding, control, and system pieces.
Quick verdict
If your build needs the extra holding capability and serious power, the Brake AC Servo Motor 1KW 4NM NEMA32 Drive Amplifier 220V CW/CCW Z Axis Milling is the clearer pick. It is a single-axis motor and drive amplifier package, and it supports position, speed, and torque modes. If you are after a complete motion-control bundle and can work with lighter loads, the AC Servo Motor Drive Kit: 220V Controller, Spindle, PLC, and Gearbox puts more components into the purchase.

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

This is the higher-priced option at USD 536.99, and it is built around a 1KW servo motor with a brake. The drive amplifier accepts single or three-phase input, and the attribute list covers input voltages from 180V to 240V. Peak torque is listed at 12 N·m. Control modes include position, speed, and torque, and the drive supports MODbus communication with RS232/RS485. The standard cable length is 3 meters. The limitation is that this is a motor plus drive amplifier package rather than a bundled system; the other listing's title names several system components, which makes that kit a broader one-purchase package.
AC Servo Motor Drive Kit: 220V Controller, Spindle, PLC, and Gearbox

This kit bundles the full set: controller, spindle, PLC, and gearbox. The attributes list 400W motor torque of 1.27 N·m and 600W motor torque of 1.91 N·m, with instantaneous maximums of 3.81 N·m and 5.73 N·m. The encoder is a magnetic 17-bit absolute unit, and the signal lines are pulse/direction. The trade-off is torque: the listed 1.27 N·m to 1.91 N·m figures are lower than the 4 N·m rating on the higher-power motor, so this kit is better suited to lighter axes, small spindles, or test setups.
Final choice by use case
For a Z-axis milling retrofit, the Brake AC Servo Motor 1KW 4NM NEMA32 Drive Amplifier 220V CW/CCW Z Axis Milling is the stronger fit. For a bench test rig, small spindle, or PLC-driven automation mockup where you want the kit's bundled pieces together, the AC Servo Motor Drive Kit: 220V Controller, Spindle, PLC, and Gearbox is the more complete package.
