Most modern stepper motors should work fine though. You are commenting using your WordPress. Stepper motor test video. Using higher microstep rates will decrease the chance of motor resonance affecting performance. Adjustable chopper current drive, no large external resisters required for stepper motor current limiting.

We recommend no more than a 44volt supply for reliable and trouble free operation. The LMD driver has internal overcurrent and thermal shutdown protection.

Fill in your details below or click an icon to log in: Please state which stepper mode you require- full step, half step or 4,5,6,8,10, or 16 microstep version. Requires external volt DC motor supply. Pcld motor is spinning at a maximum rate of RPM. Please contact us for custom microstep modes, we may be able to design and program a CPLD for your exact needs.

Just change the quantity to 5 and then add list to order. Higher step rates is possible by using a faster computer. Please attach three first class stamps to the envelope with your legible return address. We have tested the LMD driver chips continuously with a 44volt power supply.

Also available is a parallel port Stepper Breakoutor our latest optical isolation board. Only one stepper mode can be programmed into the CPLD at one time, please state which version required when ordering.

Higher rpm can be achieved by increasing motor voltage to the maximum of 55volts and using a faster computer that can output higher step rates. We recommend the 8 microstep version for most applications. You should be able to use moor about any gear you have on hand. Bare PC boards are in stock.

The maximum motor rpm was step rate limited by the PC. Please note that 16 microstep mode requires a fast input step pulse rate to achieve high motor rpm speeds. Capable of over Khz step pulse input rate. Adjustable chopper current drive, no large external resisters required for stepper motor current limiting.

On the other hand… If you would do this with a BLDC motor without sensors use the same leads to drive and senseit might get a lot more interesting: If this leaves you thirsting for more CPLD goodness check out our own guide on the subject.


Stepper motor test video. Stepper motor voltage set to 36volts, using 8 microstep mode. Notify me sstepper new posts via email.

For Astronomy users, MicrostepPLD can be used to control your telescopes azimuth and altitude stepper motors using 10 or 16 microsteps for smoother movement.

Only one version can be programmed into the CPLD at one time. Email required Address never made public. You are commenting using your Facebook account.
