BUILT-IN MOTOR SERIES
Seamless integration, zero vibration.
This 23kW built‑in motor spindle is a heavy‑duty core component designed for CNC lathes and machining centers. The integrated AC asynchronous motor eliminates belts or gears, achieving a “zero transmission” system with extremely high rigidity and efficiency. With a maximum speed of 2400rpm, this spindle is dedicated to low‑speed, high‑torque metal cutting – ideal for heavy stock removal on steel, cast iron, and other difficult‑to‑machine materials.
| Model | Bearing Dia. (mm) | Max Speed (RPM) | Power (kW) | Motor Type |
| 200KG024Y20 | 102 | 2,400 | 20 | Integrated AC Motor |
| 220KG024Y23 | 120 | 2,400 | 23 | Integrated AC Motor |
Core Advantage
-
High Rigidity for Superior Accuracy: The integrated motor design increases spindle stiffness, reduces vibration, and delivers better surface finish and longer tool life.
-
High Torque for Heavy Cuts: 23kW power combined with 2400rpm provides high torque at low speeds – perfect for heavy roughing of steel, titanium, and other hard metals.
-
Energy Efficient & Low Maintenance: No belts to wear or slip, higher transmission efficiency, quicker start/stop, and significantly reduced long‑term maintenance costs.
-
Quiet & Stable Operation: Eliminates belt noise and runs smoothly, improving the working environment.
Applicable Scenarios
-
CNC Lathes (horizontal / vertical) for external, internal and face turning
-
Turning centers requiring high power and rigidity
-
Vertical / horizontal machining centers for heavy stock removal
-
Heavy‑duty roughing of steel, cast iron, alloy steel
Questions
Q: Can this spindle be used for high‑speed machining (e.g. above 15000 rpm)?
A: No. This is a low‑speed, high‑torque design with a maximum of 2400rpm. It is intended for heavy cutting and powerful turning. For high‑speed finishing, please check our high‑frequency spindle series.
---
Q: Can I directly replace my belt‑driven spindle with this built‑in motor spindle?
A: Retrofitting requires matching the machine’s mounting interface, control system (VFD/drive parameters), and possibly electrical upgrades. Please provide your machine model – our technical team can assess compatibility.
---
Q: What is the delivery time to Vietnam, Thailand, or Indonesia?
A: For major cities in Southeast Asia, delivery typically takes 7‑15 working days, depending on local customs clearance.
---
Q: Is 23kW enough for cutting steel?
A: Yes. 23kW combined with 2400rpm provides excellent torque for deep cuts and high feed rates on steel, making it ideal for efficient roughing.
---
Q: Does the spindle have CE certification?
A: Yes, all our spindles comply with CE standards. We can provide a certificate copy to assist with import customs clearance if required.
