I have an Alien Titan bought 2 months ago. Bob of alien bikes exchanged
the battery as we thought it faulty (only running for 8-9 miles and
cutting out.) I fitted the new battery but the motor would not run at
all, Bob sent a new controller which I fitted but again motor does not
run.
It is a Suzhou Bafang 24 volt motor. The fault condition is when key
switch turned on all 3 lights are on, at the bike. Also when I measure
with a multimeter each of the 3 "phase wires" going to the motor read
24 volts measured between each phase wire and -ve wire at key switch
regardless of position of throttle.
I do not fully understand how these brushless motors function but am I
to understand that only 2 of the phases should have 24 volt (one of which is -ve) on them for the motor to turn. Is there any way I can test the motor (I have another 24 volt source)?
I have visually checked the wiring for breaks and kinks as best as
possible, also I have disconnected the brake wiring.
Bob says he has never had a motor fail so I would like to be able to at
least confirm motor is ok. I do miss being able to ride the bike as
due to my age and lack of fitness, I cannot ride it without the motor.
Thanks in advance
