Hello,
I buy 14.5 inch Electric Wheelbarrow Hub Motor kit (48V,500W (https://www.aliexpress.com/item/1005004115893822.html?spm=a2g0o.order_li...)). Together with motor I received driver and throttle which can regulate speed between 20 and 40km/h but I would like have walking speed (around 5 km/h.)
Is it possible to use VESC, MAKERBASE or FLIPSKY speed controller and set speed around 5 km/h and same time max torque?
Also I would like to start motor rotation with ON/OFF switch (not with throttle) and have option that with additional ON/OFF switch can change direction of rotation ? Is it possible?
For this motor I buy 48V 20Ah (18650 13S3P lion battery).
Which speed controller can achieved this requests? Which speed controller you recommended?
Best regards.
Yeah, you could use a vesc for this project no problem
Any of those would be good to use, I'm using a Makerbase 75100 v2 Alu on my Ebike with absolutely no issues, pushing 1200w through it, so it would be far more than enough for your project. To limit the speed and power you can use the profiles in vesc tool to set the max speed and amperage to limit the power/torque you can set this profile to be active by default when you power on the vesc.
Using a switch for throttle is easy to do, single pole single throw switch and a 4k7 pull down resistor, wire one side if the switch to 3v, the other goes to the throttle wire on ADC1, one side of the resistor goes onto the throttle wire aswell and the other goes to ground.
The reverse switch would be wired the same way except the reverse signal wire would go to ADC2 instead of adc one.
You would flip the throttle switch to go forward, and flip the reverse switch to go backwards, you don't need to flip the reverse to change direction and then flip the throttle to move, you just need to flip the one switch for the corasponding direction you want to move.
20Ah from an 3p 18650 pack is impossible, using the highest capacity 18650 cell that is commercially available has a capacity of 3500mAh(3.5Ah), so with a 3p pack that is at most 10500mAh(10.5Ah). Any 3p pack advertising more than this is lying and more than likely using fake cells, same goes for individual cells, if a single cell is being advertised as more then 3500mAh, it is a fake cell
