I have bought a custom made planetary gear motor with specification 24Volt, Rated current: 8A, Stall Current: 80A, Power: 160W.
I am going to order the Cytron MD30C Motor driver, The Motor Driver will suppy the Voltage: 24V, Continues current : 30A, Peak current of 80A.
My doubt is that is this driver is sufficient? or should I need to choose another?
Your valuable help will be highly appreciated. Waiting for replies.
I would say that the driver looks to be sufficient for your application because it is capable of up to 30A continuous current. You can also put a fuse in the circuit to prevent too much current being pulled through and damaging your components.
The one thing to be careful to avoid is suddenly switching from full speed in one direction to full speed
in the other - that's likely to pull upto twice the nominal stall current, and generally be a bad thing!
Ramping of drive level helps prevent large current draws and mechanical wear and tear too..
Thanks for replying.
If I limit the pwm with 200 value, will it change the stall torque value?

Somewhat, but you'll not get full speed either. With larger motors ramping the drive level
becomes more important (some really big DC motors cannot mechanically survive full stall torque,
for instance, but would never be driven without current sensing, protection and limiting as the
time to catch fire is fractions of a second on full stall).
