The higher the number doesn't always need more torque if u get a good handwound motor from Brood or HH whatever turn u get will have awesome torque if u will send Eddie at brood a pm and tell him what u are going to put it in and what u want it for he will hook u up

basically the lower the number the more wheelspeed, but lower runtime.

| Brushed motors, bigger number of turns = less RPM (speed) but more torque. Lower number of turns = more RPM (speed) but less torque. You can make up some of the lack of RPM in a high wind motor by going up in battery voltage (from a 2S LiPO to a 3S LiPO) provided the ESC can handle it. You can also change the gearing as well. Best bet is to get the motor wind about correct, change gearing from there. Typical range for crawlers, 35T - 55T. I run dual 35T motors in a 2.2 Bully MOA. You have to keep in mind the trans ratios as well. Worm drive rigs REALLY want a brushless motor, they tend to eat up brushed. For a given wind (say, 35T) a handwound is usually better in every way than a machinewound. The handwound will have more torque, more RPM, smoother operation and last longer. If you are running for fun, a machinewound is less expensive to buy. Since it won't last as long, it may get more expensive over time due to having to replace them more often. Also, machinewound are usually not worth sending out for rebuilds. Some of us, myself included, have our own tools & comm lathes, so we rebuild our own motors. You could contact Eddie0 or Holmes Hobbies, tell them what your rig is & what you do with it. They can help you pick a motor. Last edited by Charlie-III; 12-13-2011 at 07:05 AM. |
