Mega Motors

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.
