NPC-02446 Motor

ive heard these have a similar performance to the bosch 750w mtor and could run off 4QD NCC 70 ESC's but i want to clarify this before i do anything :lol:

Yeh, should be fine.

About 2/3ths of the power of a Bosch.

With a 10 wheel, a 14 to 1 gearratio sounds fine.

3/4 bhp each but at 4000rpm aint too bad. Since im using a flipper, speed is more what im after rather than pushing power :)

Speed is fun.

But to have speed, you need power.
If you disagree, why do have all fast cars a load of HP?

If you use a lower power motor (and bosch 750 @36V is mid power in thesadays), you have the 2 following options. High end speed but lousy acceleration and high amp draw, or reasonable acceleration and amp draw

its hard finding an alternitive to the good old 750w motor thats not making me have a heart attack when i see the price :lol:

Join the club, 11 years ago I had the same feeling, when I started Roboteering.

But after some experiments, our heavies are using Bosch 750's. Except Bullfrog Breed, that uses Iskra AMG 800W motors. Heavier than a bosch 750, but more rugged construction.

i would use them, but there are none in stock for 6 months :sad:

Try Iskra Motors, they do a1.2kw 24v DC motor :uhoh:

the type AMG motors? would they be ok on the 4qd's though?

No Idea for the NCC's, but I know a Sidewinder does the job fine @36V.
This with 10 wheels and a 20-1 gearratio.

well i know they are ok on bosch 750's at 24v but without knowing the draw of them, i cant tell if they would be ok

if geared correctly the npc motor on 36v should work fine moving your bot about at a reasonable speed. the iskras should also work with the 4qd ncc70s as to the best of my knowledge the ncc70's can take up to 100amps.

i believe that withour modifying, the 4qd's can only do 24v

I believe it's just adding a resistor of changing one to make a NCC 36V capable.

Otherwise, a Wotty, Sidewinder or a pair of Mytras or Victors will do the job in a reasonable pricetag.

my only worry is running the iskra 800w motors on NCC 70's at 24v

yeh that should be fine. an overvolted motor pulls more current and is more powerful.

i would get some ok speed out of them at 24v i think :)

With 260mm wheels, a 8-1 gearratio would be the max in 1 stage (steel Z24 mod1 on the motor, a custom Z192), and would deliver an theoretical end speed of 21km/h.

i could either use iskra 800w motors, the NPC-02446 motors, or some 24v 900w scooter motors :)
