Technical FAQ & Operational Guide

Can I run a standard 3-phase motor with this single-phase VFD?

Yes, provided the motor is rated for 230V 3-phase (usually by wiring it in Delta configuration). This VFD converts your 230V single-phase wall power into 230V 3-phase output.

Does this micro-drive require a cooling fan?

At 0.4kW, this model often utilizes high-efficiency natural cooling through its integrated heat sink, though proper cabinet ventilation is always recommended.

Can it be used for high-speed spindles?

Yes, it supports an output frequency up to 599 Hz, which is ideal for small, high-speed spindles used in micro-CNC and engraving machines.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
