| Oct 13, 2016 at 18:59 | comment | added | user22483 | I roughly need 80Nm as a starting torque. Since I have 's reduction ratio of 8 from my transmission I need 8 NM of starting torque. It doesn't matter if my car moves very slowly. Hence the above question ^ | |
| Oct 13, 2016 at 18:57 | comment | added | user22483 | Alright. Really sorry on that part. My load is a solar electric car. I'm using a 48V 1500 W BLDC motor. One of the rounds of a competition I'm taking part in requires me to remove the battery and run it directly from solar panels. Due to space restrictions the largest panel I can use is of 400 W and 48v. By 3s I meant 3 seconds. I received a catalogue from the manufacturer stating that the motor requires a continuous current of 32 amps and will give a continuous torque of 4.8Nm and it will require 60A for 3 seconds to supply 14.4 Nm at the start. I'm yet to receive the data sheet. | |

We need a lot of information to be able to answer a question. What motor are you using? What kind of load are you trying to drive? What kind of power supply are you using that can't support 60A for 3s? To what catalog are you referring? I'm not necessarily saying I can answer the question if you provide this info, but I need more info to know if I can. | |
| Oct 13, 2016 at 17:23 | comment | added | jms | It would help if you linked to the motor in question. I don't believe that your brushless DC motor needs 60A to start, unless you are designing an electric car or something. "60 A" is probably the maximum rated current. What do you mean by 3S; is this some RC equipment powered by a three cell LiPo battery? I wrote a fairly comprehensive primer on how BLDC motors behave and how they are driven a while ago: electronics.stackexchange.com/questions/262106/… | |
