Is that 500Oz inch at zero speed or running?
If running at what speed?
We have supplied stepper motors to a compnay who use them to change gear, and they were 34 and 42 frame.

The problem is most likely that you are running the motor at 2A in series and at only 24V.
Use a better driver, higher voltage and connect the motor in paralell you will see better performance.

Put your clock into pulse + and pulse - goes to ground same for direction.

Stepper will be far cheaper, but you can achieve far better accuracy and speed with a servo system.

There are plenty of places to get quality servo drivers and motors from in Europe, you just need to look.
Are you looking for brushed or brushless? we sell both.
Have a look at our site, and if you...

Yes you could consider this driver and yes i think it does.

It is not a bad price, but there is no optically isolated I/O, does not look like it has over voltage protection, and this is important if your supply is quite close to the 30V.
Also current...

During acceleration and de acceleration the peak is used, this is what is different to steppers.
Typically you get three to four times the torque in peak, and this is normally rated for about 2...

You can also do this without a PC.
You could make it your self with a pic or something like that or buy an IMS Mdrive and program it to index from an input.
If you want to change the length of the...

Yes they work well.

It needs programing, but the mdrive from IMS is a good choice.
Also avaialble with linear screw going through the center of the motor.

From what i have seen, and who we are working with at the moment for steppers, the current on the name plate is the unipolar current. (Unless it is a 4 wire motor)
As an example the FL57STH76-2808...

If you are building a new machine, you may be able to save some money, but without knowing the axact power you need, would you risk buying smaller motors if you know that what you have now works...

As they say "If it aint broke why fix it"

You are right, a cooler motor will last longer that one that is being worked like a dog.
Motors are the lower cost part and the differnce in cost between a motor that has a torque of 1.5 Nm and one...

If you push the motor hard, with lots of volts they can get hot.
If it is way overpowered and you are not pushiong lots of volts and Amps through it, it will not even sweat.
Dont get scared if it...

Motors get hot, its what they do, but it comes down to a number of factors like.
Duty cycle, current settings, voltage and ambient temp.

What i meant was if the inductance figures you mantioned for the RHT motor were parallel or unipolar ratings then things would be different, and the FL57 motor would most likely perform better...

The RHT will perform better at higher speeds due to the inductance.
But is the current and inductance you mantioned in series, parallel or unipolar?
our unipolar and parallel inductance is 1.6 mH....

It depends on the kit, we do a few and the smaller kit uses the FL57STH76-2808B, and this is a 2.0A motor in series and 4.0A in parallel.
There is no setting for 4A, and the you can either set it to...

The problem is that when you start them the voltage on the PSU goes below the rated voltage of the driver.
This can cause the driver to get a brown out (Not start)
This only happens when you put...

That is something i am working on, the reason we have not done that yet is becasue we supply the drivers with many motors with different wire colors, and the wire info is on the front of the driver....

Its due to the surge current when you start it up.
We have found that in some cases when you power the three drivers up with one power supply one or two of the drivers dont start, so we now bundle...

That motor came from us.
he also sent the link to us as well.

The Keling KL- 5056 Microstepping Driver is a very good driver.
or the

I have allways thought they were the same, i even hear them called drive amplifier.

35-40V is the best foltage to use.
The max voltage of the driver is 50V, so having the foltage at 40V gives you some head room for BEMF.

This motor is an the replacement to the FL60STH-2008BF that was a good motor, but suffered due to the high inductance.
We had this motor wound specifically to work with the MSD542 driver and the...

The DC voltage to the driver is X1.4 the AC voltage.
So you really need to be carefull when using the driver and you will need to use an isolating transformer to get the AC voltage down.
This is...
