I want to find a Cheaper replacement Stepper Motor then what the manufacture wants to sell me. It is being used in a redemption game called Slam A Winner and it drives a platter around in a CC direction all day long. They use the stepper to determine what hole the ball had fallen through. The motor that is in it is a AstroSyn 23LY-C205-03V They want 128.00 for a replacement motor.

I think this is the same spec'd motor that is used in Claim Jumper and some other Benchmark games.

My question is what specs on a stepper motor have to be matched exactly and what specs can just be close?

I know you have to get the degree correct. This one is a .9 degree and it is a Hybrid that is using only four of the six wires.

But what about the

Resistance
Current
Inductance
Torque
etc...

The Astrosyn has the following:
Model Number 23LY-C205
Voltage 4.0volts
Current 1.10 amps
Resistance 3.6ohm
Holding Torque 3000
Inductance 5.3mH
Rotor Inertia 55.0 g-cm2
Detent Torque 250 g-cm
Weight 360 grams

I know what a lot of you are thinking, it depends on the controller? Unfortuantly I think it is a custom controller and I don't have any info on it. It can't be replaced with a generic one, I am pretty sure of that.

But there has to be some general guidelines I can follow??

I have searched for answers to this question but could not really find anything. Perhaps I worded the search wrong.

Anyone help me with this?

Thanks very much,
Russ
