hey guys,
I've been really excited about this ebike build. It started out with a two year old ezee cadence I bought for $400. It's this bike:

The design is really great, and I've put a lot of work restoring this beauty. Terry from http://www.hightekbikes.com/ is building me a custom 48v 15Ah Lithium Cobalt battery out of samsung cells that I'm putting inside of the Cadence's already sturdy battery support frame. This allows me to take advantage of the removable battery support in the center of the frame, a great place for the battery. It's got the 350W geared brushless hub motor in the front.
In order to accept the new higher voltage battery, user spinningmagnets recommended I get a Lyen controller. Seen here:

I also got a cycle analyst and a cruise control. It's going to be a great setup when it's running. Problem is--it's not running. And I need your help because I've run out of ideas. I've been emailing Lyen but I need the advice of the forums to figure this out! Here's the problem. I have the motor hooked up by the way Lyen's instruction manual said. More on that in a second. Then I've got a temporary (3years old and pretty much dead) battery that came with the bike while I wait for the new one from Terry. That's hooked up. And then there's the throttle. It was wired to the original ezee controller in a weird way, so I ordered a new one, just in case I broke the old one.
Right now, the motor isn't turning at all. The old ezee controller marked the larger gauge motor phase wires as:
MA=Green
MB=Yellow
MC=Blue
and the thinner hall effect sensor wires as
+5V=Red
Ground=Black
H1=Green
H2=Yellow
H3=blue
According to Lyen's controller setup for an ezee:
Controller --> Motor:
Hall:
Yellow --> Green
Green --> Blue
Blue --> Yellow
Phase:
Yellow --> Green
Green --> Yellow
Blue --> Blue
I have hooked up the motor wires as so. And when I short the Red wire of the throttle with the Yellow wire of the throttle coming from the controller, I get nothing. The motor doesn't spin. I know the motor is perfectly fine because it worked when I was using the ezee controller. There's a few possibilities I've thought of that could make the motor not work.
1. The battery is old. Cycle analyst is saying it has 34.5V and -9W and -0.54Ah. Is it possible that the cycle analyst is cutting off the throttle to the motor because of its low voltage and amps? I've tried unplugging the CA and shorting the throttle, but still no luck. I'll be getting the new Cobalt battery here next week, so that might solve some problems.
2. The wiring diagram for the motor and hall sensors isn't right and needs to be setup some way else. How can I make sure that the right wires are plugged into the right wires? Just try different combinations?
3. How can I test that a signal is being sent to the motor? Is there a way I can use a multimeter to check and make sure that the controller is sending a signal to the motor when I short the wires to simulate open throttle? I've never messed with a brushless motor before, so I don't know how to just hook a motor up to a battery and test it if there's no positive and negative terminals.
4. The controller might not be working. It powers up the CA and sends 5V to the throttle wires and I'm also reading 5V being sent down the hall effect sensors, so I feel like the controller (besides the fact that it's brand new) is not a problem.
5. The throttle isn't reading. Though I was recommended by Lyen to just touch the red to the yellow to simulate open throttle, it's possible that the controller still doesn't think there's anything going on. Any other way I can test the throttle?
Let me know what you guys think. Here's some pictures for more information! Thanks!
The wiring diagram on the back of the Lyen controller:
The leads coming from the ezee hub motor that have been spliced and added to the control plugs Lyen provided:
The reading of the CA when I first turn on the controller:
The wiring from the motor plugged into the Lyen controller:
The throttle wires coming from the throttle, but don't work when I hook them up to the Red, Black, Yellow units on the controller. On the original ebike controller it was Red, Black, and Brown hooked up. Any thoughts?
