l 2m/s start-up wind speed under low torque starting technique (0.7n/m). l Light generator about 7kgs, easy to install.The generator was casted by aluminum,so it can endures high temperature,all together it has 27 slots,and its slots is skew.So it can lower the logging torque, what's more,the gap between stator and rotor is very small.So it is not only lower the start-up wind speed,but also guaranteed the electricity's efficiency. Our generator have a long life span,it is more than 20 years. l The blade casted into molding at one time with balance up to 99%.It has a stong ability to resist the strong wind. l The tail processed with reinforced rib. l Matched controller with PWM charging, electronic and manual brake, and numeral panel display. 1 We use carbon brush to prevent twisting, it can be use more than 100000 times.
