Brussless Spindle Motor is an abbreviation for “brussless spindle motor. Input Voltage: 48V; Rotating Speed: 12000 R/Min; Torque: 0.45 N.m; Collet: ER8; Insulation resistance > 2ohms; Dielectric strength 400V.
Please keep in mind that this spindle motor output shaft is equipped with an ER8 collet, and that the output shaft is a complete shaft that cannot be exchanged for an ER11, ER16, or any other type of chuck shaft unless the spindle motor is replaced.
Driver for a Brussless Spindle Motor (Brussless Spindle Motor Driver.
Maximum driver power is 600 watts; voltage range is 24 volts to 60 volts; maximum driver motor running speed is 12000 revolutions per minute.
The brushless spindle driver (Model Name: NVBDL) is designed specifically for the economical engraving machine, and it works in conjunction with the brushless DC motor. When compared to current drivers, the updated DSP technology allows the driver to drive the motor at a more precise speed and with a greater amount of torque output.
The panel can be removed from the main driver and installed on the controller cabinet, if desired by the users.
By using the panel, you can adjust the parameters, control the motor speed, and start and stop the motor, which is extremely convenient.
I don’t usually leave reviews, but the quality of this spindle convinced me that it deserved one. When I first opened this up, the first thing I did was set it up on a bench so that I could measure the spindle runout. If it had been less than a thousandth of an inch, I would have been satisfied with it.
I started by taking the collet out of the taper and measuring the runout on the inside of the taper. With a thousandths of a percent indicator, the needle did absolutely nothing. Once again, there was no movement on the indicator after I cleaned out the taper and collet and installed a new 1/8″ endmill. I measured the runout from the collet to be approximately 1/2” and found that there was no movement. The indicator appeared to be stuck at first, so I tried another and received the same results. Despite the fact that I don’t have a tenths indicator, I would guess that the runout would be measured in fractions of a thousandth of an inch or less.
The controller functions flawlessly, and the PCB appears to be of good quality, with a generous heatsink on the mosfets for added cooling. When in operation, the spindle is relatively quiet. With a 36V power supply, I’m able to achieve a maximum speed of 9600RPM.
It does not come with instructions, but the link provided is sufficient and, if I were so inclined, I could easily configure this to be controlled by the CNC controller. I, on the other hand, prefer to control the speed manually.
I’m running it on a machine that looks a lot like the Nomad 883. This is almost certainly a better choice than a palm router for most people who are running a hobby CNC router made of aluminum extrusion and belts for positioning. You won’t be able to use the full 1+ HP of the router because of the flex of the extrusion and stretch of the belts. They are also extremely noisy, and the low end of the RPM range is usually around 8k-10k rpm, which means you’ll have difficulty dialing in your feeds and speeds appropriately for many materials.
The only issue I have with this kit is that the LCD extension cable is only 4 or 5 inches in length, which is too short. It would be much more effective if it were 3 feet or so in length.
