Servo motor and driver for CNC axes
Every axis servo is a servo motor and driver pair: the driver must match the motor's power and encoder. The 750W servo motor is the most common size on CNC routers' X and Y axes; 400 W suits light axes and 1 to 1.5 kW suits heavy gantries. Choose a braked motor for vertical Z axes so the axis holds when power is off. A closed loop servo motor system can be bought as a servo motor kit (motor, driver and cables). If you are comparing servo motor manufacturer options in India, compare rated torque, encoder resolution and driver support; we quote complete axis kits.
Servo vs stepper motor for CNC
| Factor | Stepper motor (open loop) | Closed loop / hybrid servo | AC servo motor |
|---|---|---|---|
| Feedback | None; position assumed from steps | Encoder on the motor | High-resolution encoder |
| Lost steps | Possible under overload | Corrected by the driver | No; drive alarms on following error |
| Torque at high speed | Falls quickly above a few hundred RPM | Better than open-loop stepper | Flat torque to rated speed (often 3000 RPM) |
| Cost | Lowest | Medium | Highest |
| Typical CNC use | Small routers, light axes | Mid routers wanting stepper cost with feedback | Production routers, laser, plasma, VMC axes |
CNC Servo Motor: frequently asked questions
What size servo motor do I need for a CNC axis?
Work out the torque needed to accelerate the axis mass plus cutting force, at the screw or pinion, then divide by any gearbox ratio. As a guide, light router axes use 400 W, typical 1300 x 2500 mm router gantries often use 750 W per side, and heavy or fast gantries use 1 kW to 1.5 kW. Add a gearbox before oversizing the motor.
Servo vs stepper motor for CNC?
Steppers are cheaper and simple but can lose steps under overload and lose torque at high speed. Servo motors use encoder feedback, keep torque to their rated speed and alarm instead of losing position, so they suit production routers, laser and plasma machines. Closed loop stepper (hybrid servo) systems sit in between on cost and performance.
Our servo vs stepper motor for CNC router guide shows when each makes sense.
Do I need a servo motor with brake?
Use a servo motor with an electromagnetic brake on vertical or inclined axes, such as the Z axis, so the axis does not drop when power is cut or the drive is disabled. Horizontal X and Y axes normally do not need a brake.
