I bought a surplus sanyo denki step-syn stepper motor whose data is as follows:
1.5A 0.72 deg/step
Type 103H7522-8051
Lot No. 10609
5 wires
I dont have the coil or circuit diagram. Can anyone help in providing me the coil diagram so I can make the proper connection to my driver ?

I have some bad news for you. Unless you find a matching Vexta 5-phase drive for your motor, it will be useless. To my knowledge, only 2 companies in the world build drives for that motor.

No one else supports them because they are Edsels or dinosaurs. Microstepping 2-phase drives have eliminated the purpose and intent of these motors. I think it is unconscionable for someone to sell these motors without a matching drive. Otherwise you buy a motor with no chance of ever finding a drive to run them with.

Without the Vexta drive you have bought yourself a very nice paper-weight.

Sorry, but that's the reality.

Thank you Mariss for your comments. Anyway, I will still try to look for the matching drive.

Hello kheri, I have 5 Vexta stepper Driver, UDX5114, and they work perfectly..I found them in a second hand industrial Area in Kaohsiung, Taiwan..
Each supplier sells different price but overall price are still chep,price is negoatiable. The 1st 3 drivers I bought for 800 NTS, which is equivalent to 13.3GBP(Pounds)...and the 2nd supplier sell it for 500NTS = 8.3 GBP(Pounds)..
