I just finished my "mini Golf Cart" project.
I bought a 48V 1000W BL1020 brushless motor rated 3000 rpm. I bought it combo with its own controller.
Project facts:
Vehicle Weight: about 300lbs
Passengers Weight: about 300lbs
Axle sprocket: 41T
Motor Sprocket: 10T
Tires/Wheel: 13" total
Chain: 428
During my first test drive, I noticed that the motor and the motor cable got extremely hot...to the point that the protective flex cable tubing melted and smelled like burning. Also I noticed that the performance reduced dramatically about a minute after the initial test drive, meaning when the motor got extremely hot. Also is good to mention that the motor cables and the controller cables are the factory ones, meaning I didn't cut/extend any cables. Also is good to mention that some similar commercial golf carts (ie Cricket sx-3) is using 36V-1000W motor or 36V-800W brushed motor rated 5000rpm with 30:1 gear ratio - 13" tires.
1- Can anyone suggest why my 48V-1000W motor gets burning hot?
2- Also do I need a motor with gear reduction for better torque and performance?
3- Based on the specs mentioned above, can you please recommend what motor I need to buy (brushed/brushless/with gear reduction/ Power(Watt)/36V or 48V)?
Thanking you all in advance,
LL
