General Discussions / New member with seized 5kW motor
« Last post by Marcogi on October 06, 2025, 12:11:58 PM »
Hi, I’m a new member.
I have a Golden Motor 5kW BLDC motor that has mechanically seized after a few hours of use.
It’s completely blocked (cannot turn by hand). Bearings are OK, but I suspect a rotor–stator contact or magnet shift.
Can someone confirm the correct internal structure (axial flux) and provide disassembly instructions or photos?
Thanks!

Hi, I just converted a friends trike to e-trike and am now researching all things related to e-motors.

Electric Boat Conversions / Sailboat Motor Conversion - 5kw or 10kw?
« Last post by PipeDreamIII on September 09, 2025, 07:33:42 PM »
Hi All,

I'm looking to convert the motor on an older Hughes 26 Sailboat. The boat weighs about 4500lbs, and has a hull speed of just over 6 knots. I'm debating between the 5kw and 10kw motors. I'd like to hear from others what they've put in and what they would recommend.

Thanks!

Hi andto the forum.

Did the three LEDs on the throttle all light up when the battery was connected and turned On? If the LEDs were not lit up, it could be a battery problem.

If the motor has been completely submerged in water, the motor's controller and bearings may have been affected by short circuits or corrosion, especially if it was salt water.
However, if the wheel still rotates easily by hand, the stator and magnets may still be salvageable, but the motor would need to be dismantled to see the full extent of any water damage to the magnets, the laminated steel stator assembly and possibly the steel legs on the Hall Sensors.

If the entire trike has been under water, there's also the possibility that the water might have affected the throttle and/or the various connectors on the wiring harnesses as well.

Start by carefully checking all the connector pins for signs of water residue or corrosion, especially the 5 pin throttle connector and the main 10 pin connector between the main harness and the motor harness.
If you find any water residue, clean and dry the connectors thoroughly and see if it makes any difference.

Unfortunately, the controllers have been known to fail if water gets inside them, but you would have to remove the controller assembly to check for any signs of water being inside the controller. . :(

Magic Pie & Smart Pie Discussions / New user/ aquired a drift trike
« Last post by JDunno on July 19, 2025, 03:25:06 AM »
Hello, name is JDunno. I've just registered here because I'm completely lost when it comes to electric bikes and trikes. I'm an old school combustion engine guy, trying to get up to par with the electric side of things. I've acquired a drift trike that has the golden motor on the front big wheel with a 48v battery that locks in place on the back. Upon getting juice in the battery and turning it on, I got no response from twisting the throttle. So I got ro checking things out and come to find the front wheel motor is or was completely full of water. That's where I'm at with it now. Was wondering if it's salvagable or do I need to replace it?
   Thanks in advance for my confirmation as a memeber and for any responses I may recieve.

Hi SilverFixer
There are eight different versions of this controller.
The model number starts with a letter followed by 6 or 7 digits.
Please let us know which one you have.

Have you seen this:
https://www.reddit.com/r/ebikes/comments/ucjgnr/diy_torque_arm/

A spanner can make a crude but effective torque arm when secured properly, unfortunately the one in that photo would not be very effective if regen were used, as the axle would simply twist the spanner away from the bolt being used as a stop.

Of all the torque arms I have seen, I think these are the best torque arms currently available for hubmotors with 14mm solid axles:



Click on the above picture, or watch the excellent video here for further information.

However, with a price tag of $55 (USD) this quality item isn't cheap.

Hi Alan.  You are correct except the axle spinning is not the root cause.  The problem is the repeated accelerate/decelerate cycle listen the nut. This not only allows the axle to spin, but eventually drop out.  Keeping the nut captive and tight has eliminated this risk.
