XC-ESC 8S FOC driven Ultra-High-Power Crawler Motor

New from XC-ESC comes their GL4990 8S FOC Driven, Ultra-Powerful Crawler Motor.  Powered by an upgraded FOC algorithm, the motor delivers exceptional low-speed torque for superior performance and compared to conventional motors benefits from 24% Less Power Loss and 8% Higher Efficiency.  With significantly quieter operation, it is equipped with a built-in high-precision magnetic encoder chip, it delivers real-time, accurate rotor position feedback.  Compared to traditional Hall sensors this gives dramatically higher precision (by dozens of times), strong Anti-Interference capability, and zero delay under extreme conditions.  Features a high-precision balanced and wrapped anti-explosion rotor with patented magnetic circuit design, combined with ultra-thin silicon steel sheets and high slot-fill enamelled wire, it effectively reduces operating temperature and energy loss.  Ultra-Low cogging torque significantly reduced torque ripple and delivers smooth low-speed operation.  Built to IP67 standards, this offers exceptional protection against dust and water ingress.
