Controller or Motor problem?

[General Lee]

1. I am from germany, so sorry for my bad english.
2. I really do not know if my topic is right here, but it seems to me.

3. The Problem i have:

I have a 72V-System from Crystalyte with a 7240 sensor less Controller. On a ride i ripped off the Motor cable. I fixed this already.
Now i wanted to do a test ride. If i am just lightly turning the throttle the motor starts to spin (about 5 km/h). Then when i turn the throttle more the motor brakes down and stop´s turning. I have to wait a little bit and then it turn with about 5 km/h again. Increasing the Power the motor brakes down again. Is it a problem with the controller or the motor?

Thank for a tipp

As a guess, was it a throttle fault?

Nope... i didn´t ty the phase down all the way. They scratch on the inside of the enclosure and after a few spins they made a shortcut to the motor case an to each other.
