    Two questions about BLDC motor control

    HI, so sales@uumotor.com? Sorry, to clarify: Using the buck converter to supply 5V also seemed to work on the multimeter similar to the 3.3V. However, I didn't try using the buck on the oscilloscope, it may have been a square wave. One important thing I realised was that I was quite possibly...

    Two questions about BLDC motor control

    Hi, Just a quick one. Yeah, when I asked the seller how many poles the motor had, they said it had 'three'. Not sure if that is a language issue or they don't know the difference between phase and pole. But God knows where they got that voltage range from. I could not get the motor open, and...

    Two questions about BLDC motor control

    Hi Sid, I may well have to work something out to go between the hall sensors and the microcontroller. Maybe using op-amps and voltage divider. I have spoken to the seller and they have said that the hall sensors are powered by between 48v to 54VDC! This is a lot higher than the 5 v I was...

    Two questions about BLDC motor control

    Hi Sid, Thanks again. I think I did understand you correctly; you clearly have a world of experience with Hall Effect sensors, more than me. So I don't want this to sound like I'm telling grandma how to suck eggs, but everything I've seen regarding the three Hall sensor pins is that they are...

    Two questions about BLDC motor control

    Thanks heaps for the reply Sid. I am using an arduino for the analogue to digital conversion from throttle to pi. So if worse comes to worse I'll just use the Arudino. However, my reasons for using the pi are for learning/practice purposes. A larger multi-year project of building a single phase...

    Two questions about BLDC motor control

    Hi, I am new here. I have purchased the common Bora 1800W motor: https://www.aliexpress.com/item/New-1800W-48V-Brushless-DC-Motor-Electric-Scooter-BLDC-Motor-1800W-48V-Electric-Motor-Electric-Scooter/32653016751.html I have seen other people discuss this motor on the forums. However, I am...
