3.0kW - 3.5kW ATC Spindle Motor

Known model facts#

Product overview#

This product page groups the compact CINKR ATC spindle platform from 3.0kW to 3.5kW. It covers the 3.2kW Basic BT30 spindle, Model A BT30, the higher-rigidity Model B BT30, and Model C with HSK 40E tooling. Use the 3.2kW Basic version for cost-sensitive 12,000 RPM ATC work, Model A for general BT30 productivity, Model B when rigidity and thermal stability matter more, and Model C when HSK 40E balance and clamping security are the priority. Electrical values must be matched to the spindle laser label and supplied parameter table. The 3.2kW Basic data uses 400 Hz at 12,000 RPM as the operating reference, without a separate expanded max-frequency value.

Frequently asked questions#

Can this ATC spindle be connected directly to mains power?#

No. It must be driven by a correctly configured VFD. Direct mains connection can burn the coils.

Which VFD control mode should be used?#

Use V/F Control mode only. The operation manual says not to use Vector Control mode.

How does the 3.2kW Basic differ from Model A Standard?#

The 3.2kW Basic runs at 12,000 RPM with a flat torque curve (3.2 Nm throughout) and uses 400 Hz as both rated and max frequency. Model A Standard runs up to 24,000 RPM with 800 Hz max frequency and torque tapering to 2.0-2.52 Nm at top speed.

When should I choose Model B Pro over Model A Standard?#

Choose Model B Pro when rigidity and thermal stability matter more than raw speed. Model B Pro uses enhanced body structure for heavier compact milling cuts.

What is the max VFD frequency for each model?#

3.2kW Basic: 400 Hz. Model A Standard and Model C Max 4P: 800 Hz. Model A Standard and Model B Pro 8P: 1,200 Hz (220V) or 1,200 Hz (380V). Always match the VFD max frequency to the spindle laser label.

What cooling flow is recommended?#

The commissioning reference is 5-8 L/min with 8 mm OD / 6 mm ID cooling tube where liquid cooling is used.

Can tool change be triggered while rotating?#

No. Tool change should only be triggered when the spindle has fully stopped.

What information should I send for model matching?#

Send power class, BT30/HSK 40E interface, 4P/8P, voltage, max RPM, VFD frequency, machine type, material, and photos.
