AC spindle servo drive and motor: how the system works
On CNC lathes and VMCs, the spindle servo motor turns a belt driven or geared spindle, and the AC spindle servo drive controls it from the CNC's speed and orientation commands. A spindle servo motor for lathe use needs strong low-speed torque for heavy turning and C-axis or threading control; a spindle servo motor for VMC use needs fast acceleration and orientation for tool changes. As a spindle servo motor supplier in India, we quote the motor and drive as a matched pair.
CNC spindle servo motor price
CNC spindle servo motor price depends on rated power, base and maximum speed, frame size, encoder type and whether the drive is included. Send the machine model or the old motor's nameplate and we quote a matched motor and drive. When comparing spindle servo motor manufacturer options, ask for the torque-speed curve, encoder type and drive compatibility; we supply spindle servo motors across India.
Spindle Servo Motor: frequently asked questions
What is a spindle servo motor?
A spindle servo motor is a high-power AC motor with an encoder that drives a CNC machine's main spindle under closed-loop control. Its drive regulates speed and torque precisely and can stop the spindle at an exact angle for tool changes, threading and C-axis work, which a plain induction motor on a VFD cannot do accurately.
Spindle servo vs induction spindle motor?
A spindle servo motor uses encoder feedback, so it holds torque at low speed, accelerates quickly and supports orientation and rigid tapping. An induction spindle motor on a VFD is cheaper and fine for constant-speed work, but its low-speed torque and positioning are weaker. CNC lathes and VMCs usually use servo spindle drives; routers use VFD-driven spindles.
