AMMO 20-4300KV BRUSHLESS MTR
Great for small, fast, high performance airplanes, from flat foams
to built-up 3Ds Electrifly's Ammo Brushless Motors are designed
and produced with high quality, power, precision and efficiency in mind.
All 20 size Ammo motors share the same physical size and construction,
but differ in kV (rpm per volt) power ratings.
FEATURES: Sensorless design requires a Sensorless Electronic Speed Control
Slotless design that offers numerous performance advantages including
Patented method for overlapping the winds allows for more copper
to be packed inside the can to generate exceptional power
No heavy iron teeth with air gaps in between results in no cogging
which increases efficiency, responsiveness, and power output
compared to cheaper slotted motors
Precision bearings make these motors very reliable and virtually
maintenance free (ABEC3 shielded)
Uses Neodymium "rare earth" magnets which are the strongest permanent
magnets available with one of the highest temperature ratings in
radio control at 302°F (150°C)
Uses magnet wires with one of the highest temperature ratings in
radio control at 392°F (200°C)
Can be used for direct-drive or geared applications
Very low RF and electromagnetic interference, poses less risk to
on-board radio control radio system
Two sets of mounting holes (one set of holes is spaced 16mm apart,
requiring 2.5mm machine screws. A second set of holes is spaced
16.8mm apart, requiring screws which are 3mm in diameter)
Stainless steel output shaft
Two year warranty
INCLUDES: One Ammo motor
Three high performance, gold plated, bullet connectors
REQUIRES: An Electronic Speed Control such as the Electrifly SS25 (GPMM1820)
A 2mm prop adapter if using direct drive
A gearbox if wanting to run geared (not currently available)
Three gold plated, 4mm female bullet connectors - GPMM3115
SPECS: Length: 1.57" (40mm)
