XM3542EA-18 V3

3rd generation Dualsky EA series engine with improved DUROTATE rotor. A line for the most demanding users.

Features of EA DUROTATE motors compared to CA series:

• DUROTATE rotor - changed shape of the rear part of the rotor, improved efficiency of the engine in the middle RPM range, reduced air noise (the DUROTATE rotor is not compatible with the earlier version of the engine)
• improved stator base (front part of motor) for better heat dissipation
• increased engine efficiency due to greater precision of stator and rotor matching (smaller gap between stator and rotor)
• the possibility of vibration has been reduced to a minimum, so that the EA series motors can withstand higher loads
• the winding is thinner, covered with a varnish resistant to higher temperatures (insulation), thanks to which the insulation is better and at the same time the internal resistance is reduced
• the different profile and shape of the stator base makes it easier to mount the motor in tight hulls and provides better cooling
• a wider selection of EA series motors with optimally tuned KV (revolutions per Volt) allow for the most appropriate engine selection for a given application
• EA series motors compared to the CA series in the same size class provide 10-20% more power and at the same time the efficiency increases by 3-5%.
