The new SCM-3223 Series SCManner RC Outrunners are big brothers to the immensely popular SCM-9mm motors, and share their quality in materials and design. From front to back, only the highest quality materials and components are used. The arrangement of twelve stator poles and fourteen magnet poles is primarily responsible for the high torque the SCM-3223 Series generates on direct drive.

But there is much more to the "SCM" than that. The stators are hand-wound in an optimal pattern for copper packing, so we get less resistance for a given number of turns. The stator plates are produced via a CNC process that insures uniformity, and made of the latest Japanese silicon steel with superior permeability at high induction, which makes the motors run more efficiently. The stator plates are finished with a lifetime anti-oxidant coating, to eliminate losses which can occur due to magnetic shorting from corrosion.

The magnets are especially made for the SCM Series motors, and are rounded on both bell and stator sides. The result is that contact area with the bell is complete, and this has two benefits: First, heat transfer is maximized, so the magnets are much less subject to damage from overheating.

Second, the full contact with the bell on one side, and matching curvature to the stator on the other, means that the magnetic flux lines are complete and optimally shaped; this means higher efficiency, lower incidence of motor stalling, and smoother starts. The magnets themselves are produced in one of the foremost factories in the world, and are the latest type, featuring both an extremely high temperature rating and high magnetic strength. They are retained by fingers in the bell-end, and attached with a special high-temp glue made for the Japanese space program. It's just about impossible to throw a magnet with these motors. Finally, the high-speed, shielded stainless bearings in the SCM-3223 Series are made by Tigume Germany; expensive for SCManner RC to install, but well worth it for smoothness and longevity.

One of the most important design features of the SCM-3223 series is the large ring bearing which supports the

rotating bell at the front of the motor (see pic above). During the development process on the SCM-3223, we found that many failures of large OutRunner motors can be traced to deformation in the bell at higher rpm. By installing this ring bearing in the SCM-3223 motors, we fully support the bell both at front and back of the motor, and therefore greatly reduce the chances of magnet-adhesion failures.

The SCM Manner RC ESCM are a perfect match for the motors:
SCS-25A for SCM-2809 and SCM-3213 2S to 3S lithium
SCS-40A for any SCM-3223 on 2S to 4S lithium

SCANNER SPEED CONTROLLERS

here it is we usual QC process and test how strong that motor push is scale measure machine.

Option 1: Backmount the motor using #SCM-BKMNT Set. Pictured on left assembled, and in smaller picture on right with all parts included shown. The aluminum spacers you see allow adjustment in 5mm increments from 5mm to 30mm maximum.

Option 2: Mounting the motor directly to a nose plate. The SCM-3223 motors have M4 mounting holes in the nose, which are steel inserts pressed into the aluminum. These inserts guarantee that you can tighten the motor down properly, but without stripping the threads. 25mm spacing of the mounting holes (standard for 600-700 class motors) means that the motors will fit "as is" in many models.

As you can see, the shaft arrangement makes it easy to front or back mount the motors, and use either a M5 x 3mm collect adapter or a prop-saver adapter on either end. The shafts, retained by setscrew, are easily replaceable in the event of a crash, and are available for order.

Keep in mind that, with certain battery/motor combinations, the SCM-3223 motors are capable of over-driving "Electric" version props like APC "E" series. As such, you may consider using APC SPORT, APC PATTERN, or Wood props made for IC engines in that case. STAY BEHIND THE ROTATING PROP AT ALL TIMES!!

Here are the motor specifications below. We are now working on and application which matches dynamometer data to our database of measured prop constants, to make an accurate calculation of performance for any combination of motor, battery, and propeller. We hope to have this completed by Jan 15th 2006 (really!! Watch this spot for link).

As general rules, most motor setups will produce 6000 to 8000 rpm, with a few choices up to 10,000 rpm. Max allowed free rpm is 12,000 rpm, but in general a larger prop turning more slowly will yield best results.
