Default motor wattage/kv

lets see how fast you folks are?

ready .....

Who can tell me the watt draw and or the kv of Integy lathe motors?

For 35 45 55 65 turm motors..........Go

I just bought a bridge and some waterfront property I'll gladly give to the winner.

I'm gonna guess 1.21 jiggawatts for all of them.

Depends on battery voltage, if its stalled and a bunch of other circumstances.

Brushed motors really don't have Kv ratings. There are so many variables that need to be taken into account to give you a good answer. Comparing brushed motors to brushless motors is like apples to oranges.

Current draw is directly related to the voltage and load placed on the motor, as well as it's internal resistance (number of winds and turns). I think the best way to answer this question is

65 very slow
55 slow
45 medium
35 reasonably fast - for a crawler

RPM wise, unloaded speeds are a whole lot different then loaded speeds.

Current draw - expect anywhere from 5 or 10 amps on the low side, and as much as 50 to 75 amps with the lower wind motors, under a really heavy load, or stalled condition. Starting current is really high. As much as 100 - 150 times the continous current.

The most I have logged was (64) amps using a 35T motor. Wattage was low (483) because the pack could not handle the load. Watts would have been higher but the 11.1V lipo was dropping to 7.54V under the load.

Motor speeds are on this page here

The integy motors are almost identical speed no load, but under load they drop down more. Wattage depends on the batteries more than anything, and more than about 150w continous will start to smoke a cheap motor.

Yeah I was using your motor speeds when testing some of the motors I had laying around. I was testing them with no load and RPM is higher on the cheapy motors. I have since been spinning them up with a prop. I have not tested RPM yet with the prop but the nicer hand wound motors pull more amps/watts and sound faster when under a load. I guess I need to hook up my RPM sensor to the prop and get some real/better data.
