How about The NTM Prop Drive Series 35-36A 1400Kv / 550W??? it said 7 turns.. but no poles??

poles

2620-1900Kv Brushless Outrunner - Mfr/Brand unknown; supplied with Hobby King 'Bixler' airplane: 12 magnets/poles
(Same motor is used in Banana Hobby 'SkySurfer' for Brushless upgrade option)


2815-1050Kv Brushless Outrunner - Mfr/Brand unknown; supplied with Phoenix 2000 Glider: 14 magnets/poles

30-20-1350Kv - Mfr/Brand unknown; supplied with FlyZone Cessna 350 Corvalis;
Motor has 14 poles (magnets) and 12 winding 'teeth'

Rimfire 400 has 14 poles based on calibrating RPM with RPM meter.

I'm looking for the number of poles on a Turnigy G32 - 600Kv motor...

Thanks

Its not just the pole count that you need. I found that not all ESC's can be programmed for the poles, Here's an extract from Eflights 60 amp ESC that cured my Telemetry problems, and might be whats driving others crazy:

Programming Menu 3 – Timing
The default setting is 15 degrees. As a general rule, lower pole count motors use lower timing and higher pole count motors use higher timing. Please refer to your motor instructions and specifications for an indication of the number of poles. (Default is 15 degrees)
LowTimingAdvance
Timing Degrees – 5 & 10
Motor Poles – 2 to 4
Expected Performance – Good balance of power and efficiency
Motor Poles – 6 or more
Expected Performance – Best efficiency and run time (lowest power)
StandardTimingAdvance
Timing Degrees – 15 & 20
Motor Poles – 6 to 12
Expected Performance – Good balance of power and efficiency
Motor Poles – 14 or more
Expected Performance – Best efficiency and run time (lowest power)
HighTimingAdvance
Timing Degrees – 25
Motor Poles – 12
Expected Performance – Highest power, less efficiency
Motor Poles – 14 or more
Expected Performance – Good balance of power and efficiency


1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 3 times, indicating you are now in Menu 3.

2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the Timing programming.

a. To select 5 Degrees, (2 to 4 Poles*) – You will hear 1 short beep. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

b. To select 10 Degrees(4 to 6 Poles**) – You will hear 2 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.


c. To select 15 Degrees (6-12 Poles**) – You will hear 3 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.

d. To select 20 Degrees (12-14 Poles**) – You will hear 4 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.


e. To select 25 Degrees(14-16 Poles**) – You will hear 5 short beeps
Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the first selection again.

Just received a response from HK, the tech rep says that a Turnigy G32 - 600Kv motor has 12 poles.

Melnic,
You say all Monster power from Hobby parts are 14 pole... does that include their
Tacon Monster 32? I just got word from a HobbyKing rep that my Turnigy G-32
600 Kv motor is a 12 pole motor, I'm wondering if folks are posting the correct
number WRT poles and or magnets.

Thanks

I am trying to find an AXIAL magnetic circuit motor where the number of stator poles outnumber the number of rotor magnet poles. Anybody offer such a motor?

Hacker Brushless A20-6XL 2500kv 10 pole
Scorpion HKII-2221-12 or Stock MSH mini protos Scorpion rebranded 6 poles

Don't know how others are dealing with stator counts, pole counts and such, but I finally found a much better way to go.

The problem, as I see it, is that software trying to calculate RPM gets hosed if the Poles are not correct, and the ESC timing is out of bounds, but even given correct counts, there are other inherant problems with the approach. I never could get the RPM reading to start before the motor was spinning over 4000 RPM then backing off throttle sent the calculations to 28,780 + RPMs but there is a better way.

Merely order the ground sensor SPM 1452 that is an optical sensor. Replace the Dean connector. Place the provided silver dot on the Brushless motor "can" that rotates and mount the sensor on an arm so it senses the silver dot.

My RPM readings start at < 1000 and actually will track down to 700 RPM. They are accurate at least to 14K maybe higher, and there's no false feedback when I retard throttle.

I'm sorry I spent the money and the time trying to make the electronic brushless sensor work. It was a total waste of time and money. The Optical sensor is about 5 bucks. It cost more to ship it than the sensor itself. It took me less than 5 minutes to replace the connector, and maybe another 5 minutes to glue the sensor to a reinforced balsa stringer securley attached to the firewall. IMHO this is the way to go.

Now double-confirmed: My unmodified Radian Pro turns about 7900 RPM at 10 MPH and about 8250 RPM at 30 MPH and on the ground my DX8 telemetry closely matches my GloBee IntelliTach display with the DX8 set for 14 poles.

Mega Acn 16-25-6, inrunner, has 6 poles

When I follow the calibration procedure on the PC software, I get no reading at all. Confident that my software is up to date (done yesterday) and a rhesus monkey could do the install.
Anyone got a suggestion? I'm reluctant to blame the sensor yet- but I note it's no longer in their product list.

Does anyone know how many poles for NTM Prop Drive Series 28-26 1200Kv ?
