Hello,
I am new to ASC, I am an established member of the MAA - Minnesota Airsoft Association.
I have noticed your site has for more technical info then many other boards. And thus I would like to contribute.
Here is what I have:
Eagle Force MD01 Dyno
This device measures:
RPM, Amp Draw and CONS - Motor Efficiency (lower is better), this is an arbitrary number and is only for ballpark references. Other arbitrary factors is motor noise and heat after run.
I pinned the voltage at 9V, motors spin up to a 9V draw in various times and then I let it run for a 20 seconds straight.
Motor 1 - Sacrificial Lamb
ICS Infinite - Long Type
RPM - 25400
Amp Draw - 2.12 Amps
CONS - 17
Noise - High, screetchy whiney motor
Heat - Very warm to the touch.
TM EG-3000HC (High Cycle)
RPM - 32800
Amp Draw - 2.92 Amps
CONS - 3.5
Noise - Low, it hummed with a slight pitch that reminded me of a dentist drill.
Heat - barely warm to the touch.
Result the Current King for Speed!
And now the motor you are waiting for....
G&P M170 Devil Jet
RPM - 0
Amp Draw - 18.7 AMPS
CONS - 0.0
Noise - None
Heat - None, slight vibration at 1.4V @ 17amps like the motor was trying to spin up.
Results - DOA like a cheap ACM motor. Note: It was very hard to turn even by hand. Magnet was really powerful, like Angelina Jolie to Brad Pitt on the set of Mr. and Mrs. Smith. When 4" away it latched onto the EG3000 like...well AJ on BP....
I will be contacting my distributor about the bad G&P M170.
Eagle Force EF1300 - Long Type
RPM - 27500
Amp Draw - 1.55 AMPS
CONS - 7.5
Noise - Mild, a louder harsher dentist drill type noise.
Heat - Mild, warm to the touch
Result - A great motor, very efficient due to it being hand assembled, but is it worth the price around $85.00. Good motor to reference the TM EG3000HC.
Ares/Shooter, Super Torque - Long Type
RPM - 26100
Amp Draw - 3.61 AMPS
CONS - 25
Noise - Mild, but of a different pitch, more of a thump type of pitch.
Heat - Mild, warm to the touch
Result - Definitely a super torque class motor. Magnet was very strong, hard to turn by hand, could be a cousin to the G&P M170...but this one works out of the box and at a lower cost over the G&P by ~$10.00 USD
I will be modding my G3 grip to allow my to Dyno a working motor in a AEG system. Then I can do instant spring swaps by pulling out the spring guide and run tests with different springs.
And then I will put a chrono with an RPS counter on the front.
Anyone want me to test a certain type of motor?
JG "Black, no label" - Long Type
RPM - 25700
Amp Draw - 2.72 AMPS
CONS - 9
Noise - Medium, a bit schreeky
Heat - Mild, not warm at all
Result - A fairly efficient motor, that is not as high pitched as other motors.
Chaoli "Mirco" Motor - Long Type
RPM - 21300
Amp Draw - 2.27 AMPS
CONS - 2
Noise - Medium, a not annoying at all
Heat - Mild, not warm at all
Result - Another surprising motor, being fairly low RPM it is quiet.
Classic Army Blue Label High Torque/Performance - Long Motor
RPM - 29300
Amp Draw - 3.39 AMPS
CONS - 23
Noise - Loud, high pitch, whiney motor
Heat - Medium, was arming up quickly.
Result - A high strung stock motor that is poorly refined.
Classic Army Red Label High Torque/Performance - Long Motor
RPM - 29400
Amp Draw - 4.75 AMPS
CONS - 6.5
Noise - Medium, high pitched
Heat - Mild, warming up, but not as bad as the blue label motor.
Result - The refined sibling to the CA Blue Motor.
Test with replacement motor!
G&P M170 Devil Jet
RPM - 34000
Amp Draw - 4.7 AMPS
CONS - 50.0 (Holy Moly!)
Noise - Medium High, shrieky high pitch
Heat - Moderate, was getting warm to the touch quickly.
Results - When I first powered up the motor nothing happened, as the voltage ticked up and the amps increased I thought I had another DOA motor. Then the motor kicked in and started spinning up. It was shrieky like the ICS motor, slight high frequency vibration when topped out at 9.0V. A motor at the edge and holding together, no refinement, how long it will last...that is to be seen.
