Hobbywing have introduced thee new EzRun brushless motors for 1/5 and 1/6 vehicles. The 4985, 5687 and 56113 brushless motors feature CNC-machined hard anodized aluminum case, ultra-thin silicon steel laminations, heat-resistant oxygen-free double insulated windings, high quality Japanese bearings, rotor with a strong structure and output shaft made from high quality polished alloy steel ensuring performance and durability.

Hobbywing’s temperature control technology has been designed to protect the motor from being damaged by heat thus less heat more efficient the motor will run and perform. The output performance of this motor has an efficiency rate of up to 90% (an industry-leading level). When pairing the EzRUN 4985, 5687 and 56133 motors with the Hobbywing upgraded MAX6/MAX5 ESC, the built-in temperature sensor and port will effectively prevent the motor from being damaged due to overheat and prolong its service life.
