MOTOR NAMING (MODEL NUMBERS)

What do MEGA Motors Model Numbers mean? Mega manufactures three classes of motors for RC hobby use. ACn 22 - An AC Sensorless motor with a 22mm diameter rotor. ACn16 - An AC Sensorless motor with a 16mm diameter rotor.

RC - Rotating Case brushless sensorless AC motor.

Following the rotor diameter are other numbers. The first describes the rotor length in mm and then the number of turns of wire. ACn16/15/3 is a 16mm diameter rotor X 15mm length rotor with three turns of wire per pole. ACn22 and ACn16 are 6 pole brushless sensorless motors. ACn16 motors have 28mm diameter cases which is the same as "speed 400" while ACn22 have 36mm diameter cases which matches "speed 500, 550, and 600" brushed motors.

RC is followed with similar numbers. 400 indicates "speed 400" (28mm case), 600 indicated a "speed 600" (36mm diameter case) and RC41 indicates motors with 41mm diameter rotors and a case diameter of 51mm. Mega RC motors are typically 12 pole brushless sensorless motors. The rest of the number indicates rotor length and number of turns. RC600/10/8 has a 10mm rotor length and 8 turns or wire. RC600/20 is longer with a 20mm rotor length and RC600/30 has a 30mm rotor length.

Larger motors run slower than smaller motors. An increase in rotor length or diameter will result in a motor with lower Kv or RPM/Volt.

Why do Mega Brushless Sensorless motor out perform other motors? Mega Motors are designed by Electrical Engineers and are designed specifically for RC Model applications. Mega Motors are hand wound because we can achieve maximum motor efficiency and closer tolerances than can be achieved with machine winding. We use the highest quality Neodymium magnets which are stronger than ferrite or cobalt magnets others use. All Mega Motors have sealed ball bearings, not bushings. Our motors are statically and dynamically balanced several times in the manufacturing process. The best materials are used throughout the manufacturing process. Mega motors will last longer and produce more rpm with a given load at lower current draw than the competiton.

How do you wire a MEGA Brushless Motor to a speed control? MEGA Brushless motors have three wires that come out of the back end of the motor. These three wires connect directly to the 3 speed control wires. Wire connections determine the motor rotation direction. If the motor runs the wrong direction for you application, switch any two wires and the motor will run the other direction. All three wires are "Hot" leads and should not be grounded, or hooked to anything other than the three motor wires. We have created a wiring diagram to help you wire your MEGA brushless motor.

What is the maximum temperature a Mega Motors can reach? MEGA Motor recommends that your motor not exceed 140 degrees F. As a rule of thumb, you should be able to hold your finger on the motor after operation. If the motor burns your finger or is uncomfortable to hold, it is too hot. Motors that are continuously operated at high temperatures will suffer from demagnetization of the permanent magnets and lose power. Models such as airplanes should be designed with air flow around and through the motor. For helicopters an impeller or fan blade can be added to the motor shaft to create cooling and increase air flow. Heat sinks added to the case are also a good option for cooling. Cool motors such as MEGA Motors run better and last longer.
