I have fitted a 220W brushless motor to my Taig. There are some pictures of the installation in my Album Model Engineer (model-engineer.co.uk).

I used an 86BLS71 3000rpm motor and a WS55-220 controller. I built an Arduino based control system to drive the controller because I wanted some additional features, but the controller came with a simple potentiometer that I used in initial testing and allowed speed control of the motor just fine.

Using the standard six step pulleys that came with the Taig, and the BLDC motor I can get sufficient torque from about 100 rpm up to 10,000rpm on the spindle. I like it a lot.

That’s very impressive, Peter

‘though it does seem to make a small lathe considerably bigger.

Note to self: Must have a look at that motor.

Then please permit me to be even more impressed !!

I didn't know Stepper Online had these Nema sized BLDC motors. I think this motor could be a candidate for my lathe toolpost drill.
A 24V bldc driver for this motor could be BLDC driver

My current candidate (bought one already) is this 20V cordless BLDC drill from Lidl. The parts could be used for making a tool post drill.

As a lathe spindle motor, this one has very little torque. But for making small parts, it could be OK.

edit:

Stepper Online does have a "suitable" driver and controller: Driver and Controller

The motor looks OK if it is man enough for what you want.

One caution. The first controller Huub links to (AliExpress, it's the one I used) has a 10V DC output for signalling. The motor which Michael links to specifies 5v for the Hall effect sensors, so you would need a 10v to 5v step down to drive the hall sensors.

The Stepper online controller linked to provides 5v for the Hall sensors so would be directly useable.

My motor specifies 5-20v for the hall sensors, so I simply used the 10v output to drive them.

The stepper online driver comes with a manual and supports RS485 communication. That is something that could be handy.

I am going to order the Stepper Online driver and the Nema17 BLDC 6.4A 0.25 Nm motor.

They also have a Nema23 motor ( 57BLR90-24-01) that provides 0.6 Nm torque but also requires a 14A driver.

I have received the 57 mm motor, BLDC driver, controller and tested it using a 24V power supply. To setup the driver you need a USB to RS485 interface. It took me half a day to get things wired and running.

The motor runs quit as expected. I can control the RPM between 400 and 3500 RPM and the RPM is stable under load. Below 400RPM, the motor doesn't start. I reduced the max current to 5A (50%) and still can drill a 6 mm hole in aluminium in one pass.

I am going to use this 57 mm motor to drive my tool post drill and metal router. The PCB router will get the smaller 42 mm motor.
I think this 57 mm motor is capable of driving a micro lathe spindle.

For the routers I will replace the driver by a cheaper version and use a simple pot and switch to control the motor speed.

I have upgraded several watchmakers lathe drives using a 135W 24V BLDC Nanotec motor supplied by Farnell and a ZS-X11D1 BLDC motor controller through an eBay supplier together with a 150W 24V mains power supply from either Farnell or eBay. This is not a plug and play system so several other components are needed together with some form of enclosure arrangement. In my case the lathes were mounted on cast iron bases which could house the various bits.

There may be cheaper suppliers of a motor similar to the Nanotec one but wanted to be certain what I was buying.

The Sewing machine motor kit is good on price and comes plug and play but is just a bit too powerful for a small lightweight lathe but would be good on a Pultra or Schaublin type machine.
