    New crystalyte motor - G series

    Thanks for the info on the Hall power leads. I was hoping it would be obvious but I haven't cut the connector off yet and didn't know what colors I'd find. I tested the motors NO LOAD at 64v and they both pulled 57 watts (~1.17 amps) and were doing ~520 RPM. I had no intention of running this...

    New crystalyte motor - G series

    YES !!! :!: That is EXACTLY what I was going to do also. Both motors are presently running on a controller that does not require sensors. Next step is to sort out the leads going to the Hall sensors. If you already did this, what color wires supply +5 vdc to the hall sensors? Once I know...

    New crystalyte motor - G series

    Using the above figures I was able to lace the '-TOPGUN-' rim to a Bionx motor. Both radial and 1X pattern were tested and the spoke length was as expected as demonstrated in the following photo... The Bionx motor had the internal controller removed from it 4 or 5 years ago. It now has about...

    New crystalyte motor - G series

    To anyone needing ERD for this rim: I remeasured the rim and realized I forgot to add on 12mm x 2 for the nipples I used. :shock: Corrected ERD is ~375 mm. I have corrected the figures in the following post: ===== For anyone wishing to lace the rim to something else you will need to know the...

    Axle on each side of the motor is a different diameter, different thread and each requires a different nut !!!

    New crystalyte motor - G series

    NOTE: Edited photos so they display properly... First Power UP Test... Motors arrived with the traditional '-axle sticking out of the box-'. ^^^ Nut came VERY CLOSE to falling off during shipment !!! White wire hanging out of wiring harness? Motor (NO LOAD) spinning at ~520 RPM @ 64.0 vdc...

    New crystalyte motor - G series

    Two questions I have not seen covered here: 1 - Anyone know the ERD (Effective Rim Diameter) of the 20 inch wheel that comes laced to this motor or if you have one in front of you, can you measure it? 2 - Anyone have the pinouts of the hall sensor connector? THANKS

    E BIKE MY1020GDA 60V 1000W YK43B 24-60 V Controller

    The motor you mentioned in your notes that sells for $115 has a no load RPM of 550 RPM. I have NO EXPERIENCE with this motor. I have NOT had very good experience with planetary geared motors and tend to shy away from them at least for the non standard systems I have been working with. Both of...

    E BIKE MY1020GDA 60V 1000W YK43B 24-60 V Controller

    If you have the motor I think you have it's rated RPM is ~2500 RPM at 36 vdc. With an 11 tooth gear on the motor and a 44 tooth gear on a 700c wheel the wheel would be turning at 625 RPM (2500/4) and with that diameter wheel would be doing around 50 MPH !!! Now you can go that fast on a...

    BIONX motor controller revealed

    Four of the internal controllers I blew were the newer type with current limiting. I've never had an issue with excessive current. In all cases the MOSFETs exploded while blasting down a hill in excess of 40 MPH. Most likely due to excessive back EMF from the motor. In my case the MOSFETs...

    BIONX motor controller revealed

    I can confirm what others have told you. When I removed the internal controller from my first Bionx motor and connected it to an external NON Bionx controller I used the same 36 volt (42.0 volts hot off the charger) Li-Ion battery. The system performed pretty much the same as it did with the...

    BIONX motor controller revealed

    Something that's been running around in the back of my mind is re-settable fuses. I've used them for low current stuff (1 to 2 amps) but I know they come in larger sizes. Whether or not the series resistance could be tolerated in this application would have to be determined. The way they work...

    BIONX motor controller revealed

    After sending the previous post I found the photo of the other side of the motor showing the magnets. The magnets aren't just rusted. The rust was bonding the magnets to the ends of the pole pieces! And those little green things and other blobs are pieces off the ends of the pole pieces that...

    BIONX motor controller revealed

    I dug through my junk box and come up with a Bionx motor that didn't fair so well. You will see what I mean when you see the photos. As several have pointed out the Bionx motor is also prone to water damage. There should be a clear piece of tape over the split between the two halves of the...

    BIONX motor controller revealed

    That is an EXCELLENT idea and one that I've thought about more than once. It might take a bit of playing around though to find the correct fuse size as motor winding currents can be quite a bit higher at times than what's being pulled from the battery. After going through this more than once I...

    BIONX motor controller revealed

    I've been running mine (350 watt 36 volt Bionx system) at 64 volts with a $25 sensor-less controller at the 1500 to 1600 watt level for over a year. I'll try to make a very long story short... I blew the first 350 watt motor in the first month I had it. I was going down hill in excess of 42...

    Inside the '-NEW-' BMSBattery 12 MOSFET 500 Watt Controller

    Thanks for the suggestions. I will try to be brief as this topic is about the 500 watt BMS Battery controller NOT about tires and tubes. The only reason I posted my experience was to demonstrate that this controller appears to be able to do a LOT more than 500 watts to the point where one has...

    Inside the '-NEW-' BMSBattery 12 MOSFET 500 Watt Controller

    This may be a bit off topic but I wanted to point out that when you start getting into these kind of power levels (1650 watts) you have to pay attention to the type of tubes and tires that you are using. The good part of all of this is the controller apparently can take it and so can the 350...

    I tested and confirmed that the older model DID have a cruise control function. However, since I live in the foothills of the Allegheny Mountains (3100 foot peaks) I don't have the luxury of level roads where I can use a cruise control so never made much use of it. Because I had such great...
