Nosram Cobra Brushless Motor - 10.5T

The cobra brushless motor line has been developed from scratch with the demands of hobby racers in mind.
Art. no.: 90555
Availability: 

The guiding idea was to release a motor combining the advantages of brushless motor technology with an attractive pricing.
 
NOSRAMís cobra brushless motor is suited for every challenge in onroad and offroad racing. It is available in a 6.5 turns and a 10.5 turns winding. The cobra is fully dismountable and features many of the outstanding attributes of the race proven pure spec racing motor. E. g. the PreciSensorTM system, the oversized ball bearings and the proven HDS technology have been taken over. The rotor features a strong 5mm shaft. All these details combined make the new NOSRAM cobra brushless motor extremely robust. Consequently, it can be used for a wide range of applications and can also withstand hardest track conditions.
To reduce the overall weight, the rear part of the housing is made of high quality, heat resistant plastic. The front cover consists of a heat dissipating metal in gun metal look.
NOSRAMís cobra brushless motor has a fixed timing and can be operated with sensored and sensorless speed controls. Highly flexible silicone wires are already pre-soldered. For lowest contact resistance, the connectors are gold coated.
