Hi,
Thought to use a fine DC motor, details below, but I don't know how to match a suitable DC motor driver controller to it.
I need to control the speed from an ARDUINO processor, with a supply of DC 12-13V.
Checked with seller the use of one controller, but seller just said "not possible" and he/she does not have any more info! Uuch!
The general question is: How do you match a DC motor driver controller to a DC motor?
I know of several points to be considered:
- brushless or with brushes
- suitable voltage
- suitable amperage
- torque/RPM as application needs
Note: with DC (only!) the volt + amp gives you 99% estimate to the torque... so you need to select only 2 out of the last 3 points...
Any more considerations?
The DC motor that I thought to use is:
"12V DC Electric Motor 0.65HP at 3500RPM CW"
with brushes, at 13V DC it runs at 3500RPM, and gives 260 ounce/inch torque (== 18.722 kg/cm)
Controllers:
A. not good?
Adafruit DRV8871 (Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max : ID 3190 : $7.50 : Adafruit Industries, Unique & fun DIY electronics and kits):
From 6.5V to 45V motor power voltage + 3.6A max / peak current
B. more suitable?
"VNH5019 Motor Driver Carrier" (Pololu - VNH5019 Motor Driver Carrier)
From 5.5 to 24 V + supply continuous 12 A (30 A peak)
C. Which/What is a suitable DC motor driver control to this DC motor??
Thanks
