Hallo guys,
i am student from germany and currently working on a selfmade brushless motor. I want to operate the motor with the SBL 1360 Controller and with 3 Hall sensor in trapeziodal switching. The brushless Motor contains of 6 electrical Coils( 3 coil pairs) which are connected in a star Connection. The Coils are made of 130 windins and a copper wire with a Diameter of 0,75mm. The Hall sensors are placed between the Coils. On the rotor they are 4 Magnets 2 Northpol and 2 Southpol in a alternating order. For the power supply i am using a battery with 14,8 Volts.
So my Problem is that the rotor doesnt start by himself everytime and when it starts it will get very fast which i dont install in the configuration. Futhermore the Motor sometimes doesnt get any power which i can see in the run Operation of the roborun+. The latest Problem i am facing is that i dont get any Information about the hall sensor( hall counter, hall RPM and so on) in the run Option. I think they are many Problems with my set up. Maybe a reason could be that the Controller give me a Status led flashing pattern which says short detected and sometimes overheat.
I already tried different operation modes, changed the battery, checked the coils if they are damaged and changed the connetions of the 3 phases and the hall sensor connections. I also checked if the connetions of the 3 phases are switching and they arent but between GND and VMOT they are 16 Volts from the battery.
So is it a configuration Problem, is my Controller broken or something else ? Please let me know i appreciate your help.
Thank you in Advance
