Have you measured that it really provides 100A? What controller do you use?

Does the GM MP3 Motor have any over-current protection (temperature sensor)?

I am using Turnugy wattmeter.

Well after fresh charged battery sometimes the BMS will go in protect mode due the overcurrent protection. So .......... :o ;D

I am using Kellycontroller KBS model.

Good! Me too! But, I burned my Cyclone motor due to using it without temperature thermistor (motor's monitor was not monitored).

So, does MP3 Motor have the temperature sensors inside? Is it able to work under 100Amps peaks?

Nope to have to buy the temperature sensor mentioned in your controller manual.
And install the sensor in the motor....

Don't worry the motor can handle a lot of power ;D

Sorry, I'm not so familiar with English... Don't you use the temperature sensor with the Kelly's KBS Controller?

Aaha my English is also not well... I am Dutch hahaha.

No I don't use the temperature sensor it's useless.
I am only use 48V so the motor don't get that hot....
AWhen at top speed the motor use about 10A so.....not that hot:-)

Do you use the KBS48101 Kelly Controller?

Have you ever tried to ride with the original MP3 Controller? Do you feel a big difference with the Kelly's one? Do you you use a single or double motor wheels? What top speed do you able to reach? What about hills?

I am using KBS48121L.
The diffrence is not enough to explain in words ;D
You have to feel it!
Max speed for my bike is 40 km/h.
I am using MTB 2,35 inch tire, so less top speed.
But I don't care 40 km/h is enough for me ;D

Crazy torque :o but aware with weak bike build you can destroy your motor and bike :o

Yes I have used the internal controller for one test ride.
I don't like it!

Hm... I thought that the only difference between the KBS48101L and KBS48121L controllers is the maximum peak current supported (100A vs 120A). Am I wrong? I supposed that the response time should be nearly the same in both controllers. Isn't it?

Is it 26" bike? Is the motor on the rare wheel?

So, what the solution? GM sell the fork arm to enforce the bike's fork where the motor is installed. Is it good enough? Would you recommend another one?
I understand why the bicycle might be destroyed. But why the motor might be destroyed as well?

Thanks!

Good torque arms:

Yes my bike is 26 inch.

Example:
Well if your bike dropouts fails the motor axle can move and will destroy motor cables.

Yup the current is just the difference software options are still the same.

MAGICPIE3FOC,

Could you please to provide a connection schema between the Kelly's KBS Controller and the GM MagicPie-3 Motor? What's the order in connection of the hall sensors between the motor and controller? What's about the phase leads? Is there any color match?

Thank you!

You can try first to match same colours so green to green and so on...

If it doesn't work you can try:


Kelly controller-------------Motor Phase
A-------------------------------yellow
B-------------------------------blue
C-------------------------------green
Hall Sensors
Hall A-------------------------yellow
Hall B-------------------------blue
Hall C-------------------------green
