Sanyo Denki 103H7124-0440 source or replacement

**ngwagwa** · 31-08-2020

I am looking for a UK stockist of a Sanyo Denki 103H7124-0440 UK and am not having much luck.
Can anyone point me to a supplier or suggest a suitable replacement available in the UK?
Full specs for the stepper are available here

There's a slightly lower torque version of it on Irish ebay ATM - 0.83Nm instead of 0.98Nm. https://www.ebay.co.uk/itm/SANYO-DEN...AAAOSwYgRZlwF2

Can't you find an equivalent motor from an alternative supplier? These come in reasonably std frame sizes.

Thanks. I would rather go up in torque an new to all this hence making sure I get it right.

My drivers are Stepper Motor Driver 6.0A, 80V CNC Microstepping CW8060 from cnc4you. I have enough space so am I correct that this unit will do? M57STH76-2808S as listed on https://www.motioncontrolproducts.co...tepper-motors/

Thanks

It looks about right to me but I'm not the expert on steppers. Certainly, the inductance and dimensions look compatible from what I can make out.

Perhaps somebody else could give an opinion?
