Replacing the control board with or without replacing the motor. I like matching the control board the the motor. I found most control boards fail because either dust or pood design. Next is owner

I need to add to last post on the brushless motor *Some manufacturers will use larger motor and keep the two speed belting* Dave

Thank you for your links I know most do not know motor in electronics.? I have also run cross 2 phase motors on some hard drives. What I am look at *size a brushless motor on my mini lathe* that

No - still the same.? A great example of a sensorless is the DVD/CD player - you can here it spin up, then drop to the proper RPM. BLDC motors are electrically "commutated" with speed control via

I prefer to think of a BLDC motor as any other DC motor. The difference between a brushed and a brushless motor is simply that in a brushed motor the commutation is done mechanically by the

What pros and cons of both that I do not see beyond the advertising junk? Dave

A brushless DC motor uses a VDF and 3 phase motor. The best part of *brushless type s* is they very low maintenance and last long time. The best part *brush type* is as motor slow down you get

Here are 2 chart on brushless motors. If notice they different rpm curves. They a low cost motors because of wide spread. This chart is on a typical permanent magnet motors. If noticed the wide range

Do you own a Brushless motor? Dave

They designed to look great. Dave

It’s still not wrong. Looks like they’re only showing the universal motor on AC but eh, that’s what it looks like. It’s not comparing any particular motor, it’s saying if you want high

Any time some chartbi look at want do know and see fits. Dave

When look at chart The universal motor at 20,000 rpm. Torque is about best you use drill and pipe threading machine. There chart show a poor curve. Why show a Brush motor run at 2,500 rpm when there

Looks fine to me, what’s wrong with it? Tony Sent: Wednesday, 17 July 2024 1:17 PM To: [email protected] Subject: Re: [7x12MiniLathe] Brushless mini lathe motor torque chart.

Thank posting the link By there chart looks like there selling brushless motors. Why would a chart of different rpm's and horses power. The only motor I know they got right was AC type motor. AC

I agree I plan to start thread on control board/box later.? It more fof information but is very important to almost everything around us. It is thread that can not be contained just to mini lathe.

*Brushless mini lathe motor torque chart* compare to DC motors. I know the DC motors have very high torque as the motor slow down.? The standard ac squire cage motor is about same the rpm's drop

Don't know what the leadscrew has to do with motor longevity, but if concerned with debris getting into the control box (a possibility) and shorting electronic components: LMS Part number 2562?

There are a number of things that can be done to seal the lead screw opening in the control box. That was a big topic years ago! The easiest one is to slide a garden hose washer on to the lead screw,
