Product Description
Inside Cobra Motors you will find many features that can only be seen in more expensive premium grade products. The stators are made with laminations that are only 0.2mm thick for maximum efficiency and minimum Eddy Current loses. The motor front housings feature built-in magnet spacers that lock the magnets in place, in perfect alignment with one another, and reinforce the glue joints for maximum bonding strength. On the larger size motors, there is also a lip on the back edge of the rotor can that captures the magnets and prevents them from shifting under the highest power loads. The bearings used in Cobra motors are much larger than most other brands of motors for increased life and durability, and resistance to damage from the occasional 'Rough Landing'.To serve the needs for larger size models, Cobra has introduced the new 53mm Motor Series. The Cobra 5330 motors have an 8.0mm shaft for extra strength, as well as oversize ball bearings to support the shaft and provide a long life. There are two internal bearing which measure 16mm OD x 8mm ID x 5mm thick and the outer bearing measures a massive 22mm x 8mm x 7mm! The stators are made with 0.20mm laminations for maximum efficiency and minimum Eddy Current losses. Also included on the motor are ultra-flexible 12 AWG motor leads with high-temp silicone rubber insulation with the ends stripped and pre-tinned, ready to solder on the connector of your choosing.

● Four M4 x 10mm Motor Mount Screws
