Chris_k Posted February 13, 2014 Share Posted February 13, 2014 Evening. Im trying to find a replacement stepper motor for a Pearl River Pilot 150. Been on to Miltec and they have none and arnt getting any more.The motor is for the tilt and has the model number 42BYGH905. Ive managed to find the spec sheet (My link ) but no supplier.Can anyone recommend a motor that meets the specs and fits? Thanks Link to comment Share on other sites More sharing options...
timsabre Posted February 14, 2014 Share Posted February 14, 2014 Any 12V size 17 motor would probably be OK. If it has to have those really long screws on you might need to swap them from the original one. for example this onehttp://www.ebay.co.uk/itm/1-8-Degree-12v-Stepper-Motor-/121145827395 If the original has 4 wires and you get one with 6 wires you have to ignore the coil centre taps (often black) - you can find the centre taps by measuring the resistance between all the wires. You will also need to experiment to get the wires in the right order. Link to comment Share on other sites More sharing options...
KevinE Posted February 14, 2014 Share Posted February 14, 2014 is it unipolar or bipolar drive? Moving head motors tend to be more powerful than the effects motors, have a look at this one but check the body length will fit. http://www.amazon.co.uk/DEHANG-degree-Hybrid-Stepping-Stepper/dp/B00F3TL282 Link to comment Share on other sites More sharing options...
tomscott Posted February 15, 2014 Share Posted February 15, 2014 Might be worth giving Andy at Batmink a call, they used to import a very similar fixture, called a Merlin. They used to have a stock of spare parts and they could well have a motor to fit. Link to comment Share on other sites More sharing options...
