I have been very pleased with my DAYMAK AUSTIN electric motor bike. This is the fourth season of riding around the city streets and local highways. I have had a few electrical/electronic issues which I repaired quickly. However as with all new things there is room for improvement. Wouldn't low speed reverse be nice for backing your bike into the shed or garage. How about going FASTER with MORE torque. After all that then there is the sealed lead acid battery pack. Control of the low battery cut off voltage without starting a fire. Maybe regenerative braking to extend battery capacity. A faster, quicker charger would be nice. How about a solar charger. You'll want to checkout my 12V to 48V DC-DC inverter charging circuit that uses solar energy stored in a 12V battery and charges my 48V battery pack for free at the end of this video. I have made a few of these as well as a RV charger that charges the ebike's 48V to 72V battery while the RV is being driven from town to town. I'm not the only crazy eletronics guy who thinks that these new electric vehicles are the way to go. Well I set out to make my own controller with a few improvements. I started by making my own 3-phase brushless DC hub motor controller circuit and board PC board layout. Exposed, developed, etched the PC board from scratch. Drilled out all the holes and assembled the parts into the controller board. Using my in-circuit programmer debugger I wrote up the machine language program and downloaded it. Bingo a ...

THE BEST 48V eBike Maintenance - I want to tune up hub motor, controller, LiFePO4 battery part 8

THE BEST 48V eBike Maintenance - I want to tune up hub motor, controller, LiFePO4 battery part 8 Video Clips. Duration : 5.62 Mins.
canadianwind.biz canadianwind.net Thank you for your kind comments, guys! This is important information for all motor hub users. Be very careful with the frame-motor connectors. Your frame must match the size of axis of the motor or you can break all of the controller wires and the chain. Please note as I am replacing the wheel onto the frame that is not quite secure. The frame does not have enough place to screw a nut tight to hold the connector in place. Please note that if you are not a professional machinist or handy with tools it may be better to contact a local mechanic to help. Make sure the piece will fit well over the connector. Slide the wires down the opening and secure the locking mechanism around the connector. Notice that once in place it down not move. Notice the screw placement. Several still shots show the process with the screw, the locking part and the connector. Tighten the screw until it is firm but loose. After this is tightened, place the nut over the connector. These still frames will give you a good idea of what it should look like. Hope you enjoy. Have fun and play safe.
