Questions & Answers
On EBay, I was able to locate pulleys. I'm not sure about gears, but if you haven't already looked, it's worth a shot. You could also purchase something that will fit on a 3/8in shaft and drill it out to 10mm.
Digital signals, not analog signals, control this. This isn't what you're looking for, in my opinion. I'd like a speed-controlled and reversible variable-speed DC motor. Something along the lines of a treadmill motor.
It's only the motor that needs to be replaced.
There are a few more things to think about: Transmission ratio, transmission efficiency, operating speed, and so on.br> You could use a gear transmission device, in which case you should think about the transmission ratio and efficiency. br>br>br>br>br>br>br>br>br>br>br>br>br>br>br>b The analog drive signal is used in the 4204S, with a torque of 2 at 200RPM.

br>br>I'm using these to drive the axis ball screws in a milling cnc I'm building, and I've been able to get speeds of over 2200rpm, which translates to 11,000mm/min or over 400IPM with a 5mm pitch screw. During these tests, a total of 60 pounds of mass was moved. Granted, the torque at this speed is negligible for the given voltage, but it does provide some insight into the limitations.

1. The non-metallic shafts are less expensive because of the large shaft size. Helicoidal cut couplers are heavy and unbalanced.
2. Individually wrapped wire leads - Most low-cost stepper motors are like this, but I'd rather have a cable or, better yet, a fixed circular connector receptacle like a standard M12 connector.
For the benefit of those who are perplexed, the seller's name is recommended driver (works fine even when powered by a 48V supply). Despite the fact that V=IR suggests that 48V should be higher than the rated 4, this is not the case. This motor is rated at 2 amps at 0 volts. Even though the driver's power supply is a higher voltage than the motor can tolerate when connected directly, it's fine to use a driver with a 9 Ohm impedance because the driver regulates the output.
It was an adequate performance. For the money, this is a great motor. Ezcnc manufactures professional CNC machines and primarily employs high-end motors such as Oriental motors, though we do use these on the "Z" axis from time to time. They've stood the test of time admirably. The construction and finish are nice, but the wires are a little flimsy and won't hold up to heavy cycling. On a low-cost motor, rotor inertia is high, but that's to be expected. I recommend them for light loads where torque does not exceed 50%of rated. When pushed, they quickly fall apart. Stick to high-end motors for more demanding applications. These are excellent beginner units for hobbies. The only disadvantage is that they are extremely rough, even when using anti resonance drives at high pulse rates.
These are the only motors I use when I build machines for other people. In every way, they are ideal. br>br>If I had to make one suggestion, it would be nice if the wires had a short external tube attached to the housing to make heat shrinking or wrapping the wires easier. I just TIG 1/2" aluminum tubing, but it would be ideal for those who are unable to do so.
I'm driving a turn table with it, and it seems to be able to handle about 500 pounds without stalling or missing steps. I'm guessing I'm around an 18:1. On it, there is only one ratio.
Running a Harbor Freight mini mill as a CNC is a great way to save money.
The engine is very reliable. It really works. With the right driver, there is a lot of holding power.
