Can I run this 2.2 kW 220V spindle on single-phase household power?

While the motor is 220V, it must be driven by a Variable Frequency Drive (VFD). You can use a VFD that takes single-phase 220V input and outputs the required 3-phase power to the spindle. This makes it ideal for smaller workshops and advanced hobbyist setups.

Why is this model recommended for robotics arms?

At 5.4 kg, this spindle offers an excellent power-to-weight ratio. Its compact cylindrical body and water-cooling (which doesn't blow air/dust around sensitive robot joints) make it an ideal end-effector for high-precision industrial robotics arms.

Is the ER20 collet necessary for soft metal carving?

Yes. Soft metal carving (like aluminum or brass) requires higher clamping forces and the ability to use larger material removal bits compared to fine engraving. The ER20 system provides the necessary rigidity and supports tool shanks up to 13mm to ensure accurate results.
