CNC Spindle Motor 1.2 kW, 40,000 RPM, 220V High Speed Water Cooled
The 1.2 kW Water-Cooled CNC Spindle Motor is a specialized high-speed solution engineered for applications requiring exceptional rotational velocity and fine-detail accuracy. Delivering a robust 1.2 kW output at a peak speed of 40,000 RPM, this motor is specifically designed for intricate CNC bangle making and high-density PCB drilling. Driven by a 666 Hz frequency, the spindle provides a consistent 0.42 N.m of torque, ensuring vibration-free operation even at extreme speeds. The precision internal architecture utilizes a 4-bearing P4 configuration—featuring two 7002 P4 bearings at the front and two 7000 P4 bearings at the rear—to maintain micron-level runout accuracy. Its integrated water-cooling jacket provides critical thermal management, protecting these high-speed bearings during continuous industrial duty cycles. Equipped with a versatile ER11 collet system, this 4 kg motor is the ideal choice for jewelry manufacturers and electronics fabricators requiring a compact, high-velocity spindle for delicate machining environments.

Technical FAQ & Operational Guide
What type of VFD is required for 40,000 RPM?
This motor operates at a frequency of 666 Hz. You must use a Variable Frequency Drive (VFD) that supports output frequencies up to at least 700 Hz. Standard industrial VFDs capped at 400 Hz will not allow the motor to reach its rated speed.
Is water cooling essential for this compact motor?
Yes. At 40,000 RPM, the friction in the internal bearings generates significant heat relative to the motor's size. Water cooling ensures that the P4 grade bearings remain at a stable temperature, preventing expansion and maintaining the micron-level accuracy required for bangle making and PCB work.
What is the largest tool shank I can use with this spindle?
This model uses the ER11 collet system, which generally supports tool shanks from 0.5mm up to 7mm. This is ideal for the micro-tools, engraving bits, and PCB drills typically used at these high rotational speeds.
