Building a DC Drive for the Bridgeport Spindle. February, 2004 -- January, 2007. The primary power in a vertical milling machine is an electric motor driving the spindle. In this project, I replaced the original 1-HP 3-phase 230 VAC electric spindle motor on aBridgeport machine with a 3/4-HP DC drive motor.

23/07/2011  If you have a 3 phase motor, you can use a Variable Frequency Drive to control the RPM. And if you get the right VFD, you can run it on single phase power. Common trick these days. And if you get the right VFD, you can run it on single phase power.

That is why I started considering the single ph conversion while at it.... Half the price. The DC swap might be more work than an orig replacement... But there do appear to be advantages with full torque at low rpm.

Anyone researching the problem of building a spindle quickly discovers that the majority of cost and difficulty has to do with the bearings. Quality spindles benefit from angular contact bearings fitted in opposing configurations that maximize their axial and radial stiffness while providing as little turning resistance (and likely heating) as possible in the desired operating envelope. The traditional

29/02/2020  The one that I would sell you had new abec-7 spindle bearings that I put in, three phase motor with attached drum switch, comes with a custom designed wood frame to hold it, when not in use, and an adapter plate welded to a two inch diameter support rod, used this with my hardinge horizontal.

Leadshine Easy Servo Drives Given a breakout or motion control board, your PC’s signals are converted to 2 signals: Step: Each pulse on the step line tells the motor drive to move the motor 1 step. Direction: If the polarity of direction is one way, it commands the motion to be clockwise. Switching polarity reverses direction to counter-clockwise. In fact, polarity is perhaps not the best term as it may

This is a better spindle taper than the classic Bridgeport R8, and is really the preferred taper for building a toolchanger for this mill. Aaron also recommended a set of angular contact bearings from McMaster-Carr that cost another $100, so I ordered those too. What I’d really like to do is take these goodies and create a belt driven head for my mill that’s capable of higher rpm’s than ...

DC Power Supply (Not Shown) The photo above did not show a DC power supply because the motor drives used are capable of accepting AC. That’s very convenient, but not always the case. You may need to purchase or build a DC power supply to provide power to your motor drives. One of the first CNC Controllers I built used this DC Power Supply:

This drive is nominally rated at 3HP, has a NEMA 1 enclosure rating, can accept 208-240 AC single or 3-phase power, and outputs the 3-phase power needed to drive the spindle motor. On top of what I consider to be a very reasonable price (I payed under $400 for

Planning for your Spindle Control When designing and building my cnc lathe, I quickly realized that you need to fully understand what you are trying to achieve when attempting to fully control your spindle speed with Mach3.

Like you, I mounted my VFD in a separate panel box, but I located my on the rear of the pedestal out of the way. My remote panel box houses all my controls for not only the VFD (power on/off, run/jog, fwd/rev, speed pot, start, e-stop) but also for the accessories on the mill ...

When I connect the motor directly to 12v battery it’s slightly faster. 2. There is a noise in the motor, a loud noise. It’s like Whistling. Reply. Swagatam says.
