The first set of Brushless electric motors
is the MEGA ACn 22 series based on size parameters of Mega Mini series
brushed motors and speed 600 external diameter (36 mm). They are direct
replacements in most speed 600 mounting configurations. The ACn 22 line
is six pole 3-phase AC motors with efficiency up to 88% with a 3-wire
delta wind. These motors are available in many lengths, designed especially
for direct drive applications and suitable for gearbox, electric ducted
fan, helicopter operation, and car.
Second set of Brushless motors to be
introduced were the MEGA ACn 16/15 size which are direct replacements for
Speed 400 and Speed 480 brushed motors and ACn 16/7 Speed 400 short
motors. Standard shaft output size is 3.2mm, and the dynamically balanced rotor is supported by two precision bearings. For Combat purpose a 5mm output shaft version is available on most models.
Armatures are hardened steel with Kevlar
wrapped magnets placed on two ball bearings.
Model numbers are based on rotor diameter,
length, and number of turns on the armature: 22/10/5 = 22 mm diameter /
10 mm rotor length / 5 turns. E Indicates Energy Star or less aggressive
current stingy wind. H Indicates Helicopter use. Combat motors have a
sturdy 5mm shaft.
Now also available a complete line of outrunners (RC series), suitable for
indoor to large 8-10 lbs airplanes.
Any Sensorless Brushless Electronic Speed Control (ESC) can be used with
the ACn 22/XX and ACn 16/XX Series motors. Motors have been tested with
MGM Compro, Castle Creations, Schulze, and Jeti ESC's with success.
Kontronic ESC will work but should not be used for high rpm operation.
Hacker Master ESC should not be used in their default program mode. For
the outrunners MGM Compro, Schulze and Kontronik are best suited.
