Genius Next Series moons stepper motor

[Xiquzor]

hey all,

 

I have the following problem with a Genius next series scanner (150W).

One of the scanners has a broken shutter stepper motor. The motor has the

following number on it: 17HS0601-3. Its a moons motor

 

I've been looking for a replacement motor, because this version is no longer available.

But on the official site of moons I can't even find the specs of this motor.

 

http://www.moons.com.cn/moonsweb/english/17hD.htm

 

Somewhere on this forum I found these specs,

but I don't know if this is correct...

 

StepAngle 1.8

MotorLength 34

HoldingTorque 1.6

MaximumTemperature 130

RatedCurrent 0.28

PhaseInductance 21

PhaseResistance 44

RotorInertia 38

DetentTorque 120

 

(because when I measure the resistance on the phases its 34ohms, but that could be altered because the motor is broken)

 

Now my actual question is, what would be a good replacement motor?

I was thinking about the 17HD0013 http://www.moons.com.cn/moonsweb/english/17hD.htm

those specs are close but don't completely match up so....

 

tnx

anyone?

If both phases measure 34 ohms then I would hazard a guess that this is correct. If one measures very different from the other then it is probably faulty. However, if the motor is being driven by a proper current controlled driver like a 3771 or 3772 then the resistance of the motor will not be terribly important, well not as important as if it uses a simple driver like a ULN2803. I would think you'll get away with it but it might be prudent to increase the current sense resistors by 30% or so if you are using a motor with a resistance as low as 30 ohms/phase. I've got a 17HD0013 in front of me and it does indeed measure 29.1 and 29.4 on each phase.

 

Not a complete answer but it might give you food for thought.

Lots of disco lights use those Shanghai Moons motors, Coemar, Abstract AVR, GLP etc, it might be worth browsing through a few parts lists of other light effect units to see if there's a similar one, sometimes you can get away with one with a longer shaft and then cut it down.

Hey,

 

Does anyone know where I can get some Pan and Tilt motor's for these?

 

Cheers in advance!
