Technical Specifications:
The electrospindle model ELETM QD-2 8/12 36 40E NL PP has a maximum power of 8 kW at 12,000 RPM under continuous duty (S1) and 9 kW at 12,000 RPM under intermittent duty (S6 60%). The maximum torque is 6.4 Nm for S1 duty and 7.2 Nm for S6 60% duty. It operates at a current of 24 A (S1) and 26 A (S6 60%) with a voltage of 380 V. The spindle has four poles and a maximum rotational speed of 36,000 RPM, supporting both clockwise (CW) and counterclockwise (CCW) rotation. It is driven by an inverter.

Tool Interface and Bearings:
The tool interface is HSK 40E. The spindle uses high-speed, high-precision ceramic angular contact ball bearings, with a configuration of three bearings at the front and a pair at the rear.

Cooling and Weight:
Cooling is achieved through liquid cooling via a heat exchanger. The total weight of the spindle is 20 kg.

Operational Features:
The spindle includes several operational states: S1 for tool locking, S2 for tool release, S3 for spindle rotation, and S5 for optional piston return. Tool release, pressurization, and taper cleaning require a pressure of 6-6.5 bar.

Sensors and Air Inlets:
The spindle is equipped with sensors and pneumatic connections for operational efficiency.

Performance Graph:
The performance graph illustrates the power and torque characteristics across different speeds, highlighting the differences between S1 and S6 60% duty cycles.
