UU motor has sold a lot of 12 inch e bike conversion kits and some customer use it to convert Trikke T12 Roadster to be electric. And someone does not know how to convert T12 to be an ebike. Here we share What Mr. Kevin did.
1. Get the package from UU Motor
2. First I removed the original wheel.
3.I used a file with a flat edge after marking the dropout. The aluminum is easy to file so it doesn’t take very long.
3.Then just keep filing on either side to secure a snug fit. You could also use a hacksaw but I thought the file would be more accurate.I filed both dropouts at the same time to make sure they were parallel.
For the controller wires connection, you can refer to here:
test voltage is 24V, the test load is a reactor, and the test instrument is a temperature measurement imager.
2. 30A driver test
The test voltage is 24V and the continuous current is 25A.
30A driver continues to work at 25 A for about 27 minutes, the mos temperature is 83 Celsius degrees, and the driver case temperature is 80.5 Celsius degrees. The temperature of 80 Celsius degrees is already a relatively high temperature. The temperature of the driver case is higher than the three-phase interface temperature from the temperature measurement thermal imager .
After adding a small electric fan to dissipate heat, the temperature dropped immediately and stabilized at about 43 Celsius degrees. At this time, the driver can continue to work well at 25A.
3. 50A drive test
The test voltage is 24V and the continuous current is 35A.
50A driver continues to work at 35 A for about 15 minutes, the mos temperature is 83 Celsius degrees, and the three-phase interface temperature is 86 Celsius degrees. From the temperature measurement thermal imager, the temperature of the three-phase interface is higher than that of the driver case.
After adding a small electric fan to dissipate heat, the temperature dropped immediately and stabilized at about 46 Celsius degrees. At this time, the driver can continue to work at 35 A , and the temperature of the three-phase interface is 57 Celsius degrees.
4. in conclusion
When the load is relatively large, adding an air cooling system for heat dissipation can make the driver work better for a long time with high current.
Due to the recent “dual control of energy consumption” policy of the Chinese government, our manufacturing operation has been adjusted to “run for 7 days and stop 7 days”, and the production capacity is only half of that under normal conditions.
We have tried our best to ensure the on-time production, but we are very sorry to inform you that the delivery each will be delayed by 7-15 days. Bulk order lead time are extended to 45 days at least.
You have always been our company’s most important customer. Therefore, your order will be processed first in our production line. Please rest assured that we will definitely complete the production with quality and quantity, and minimize the impact. Once the tight power supply is relieved, our production capacity will be restored immediately.
We will keep in touch with you on the progress of the order. If you have any further questions or concerns, please contact us and we will get back to you as soon as possible.
We appreciate your continued support and understanding!
