## Overview

The RATTMMOTOR 500W Brushless DC Spindle Motor Kit features a 48V air-cooled spindle capable of speeds up to 12000 RPM with minimal radial runout (0.01-0.03mm). Its brushless design ensures low noise and zero spark interference, ideal for professional CNC routers. The kit includes a versatile brushless driver with multiple speed control options and a 600W DC switching power supply, making it a turnkey solution for precision machining.

## Description

500W Brushless DC Air-Cooled Spindle Motor ER11 KitPackage Include:1 × 500W 48V Brushless DC Air-Cooled Spindle Motor ER111 × BLDC Brushless Driver Compatible with Hall and no Hall 1 × 55mm Spindle Motor Mount1 × 600W 48V DC Switching Power Supply

Review: Has worked Great so far... - It was a great price and was easy install. The only thing is I'm not sure of the actual spindle speed it seems slower. It's super quite and that's a big plus. Will update a few months in.
Review: Good but check voltage of power supply - Seems good so far and runs at low speeds pretty well, quiet and strong. One warning, the power supply has a 110v/220v switch on the side, mine was set at 220v, the motor still ran but was lower rpm, after switching to 110v, I seem to get full speed

## Features

- Air Cooled Spindle Power: 500W; Voltage: 48VDC; Speed: 12000r/min; Torque：0.6NM; Diameter: 55mm.Radial runout off :about 0.01-0.03mm;Insulation resistance: > 2 megohms; Dielectric strength of insulation: 400V.
- Spindle Motor Drvier Features Compatible with square wave with and without Hall, with potentiometer speed regulation function, external 10V voltage speed regulation function, switch function, speed output function, alarm output function, forward and reverse function, etc., and has a protective shell.
- Spindle Motor Drvier Parameters Rated voltage: 20-50VDC; Rated current: 10A; Limiting current: 15A; Support speed: support speed above 20000RPM, the specific speed depends on the motor itself and the load.
- DC Switching Power Supply Parameters Input voltage: 110V / 220V AC; Current: 0-12.5A; Input frequency: 50/60Hz; Power: 600W; output Voltage: DC 48V; Size; 215*115*50mm.
- Advantages-1 The brush is removed, and there is no electric spark generated when the brushed motor is running, which greatly reduces the interference of the electric spark to the remote control radio equipment..Advantages-2 Without the brush, the friction force is reduced during operation, the operation is smooth, and the noise is low, which ensures the stability of the equipment operation.

### ⭐⭐⭐⭐⭐ Has worked Great so far...
*by M***Y on 9 September 2023*

It was a great price and was easy install. The only thing is I'm not sure of the actual spindle speed it seems slower. It's super quite and that's a big plus. Will update a few months in.

### ⭐⭐⭐⭐ Good but check voltage of power supply
*by A***R on 7 March 2025*

Seems good so far and runs at low speeds pretty well, quiet and strong. One warning, the power supply has a 110v/220v switch on the side, mine was set at 220v, the motor still ran but was lower rpm, after switching to 110v, I seem to get full speed

### ⭐⭐⭐⭐⭐ Inexpensive, and works great. Gets to 13000 RPM per tachometer.
*by R***R on 14 January 2025*

Added this to my 1318 mill, works great and easily is integrated either MakerBase board via a $7 PWM to 0-10v board. Very low runout. And has the power to drive 1/4" bits through wood or 1/8" through light metals easily.
