新的电机,用的7.4v850毫安锂电,不到一分钟烧了四合一:
Motor............Volts...Turns...Diameter...Mabuchi part #...No Load rpm
RK370-2870......7.2...70...0.28mm......RK370SD-2870....16500
GWS EM300H...7.2...45...0.40mm......RK370SD-4045....22950
GWS EM300......7.2...33...0.45mm......RK370SD-4533....34000
GWS EM350......6.0...28...0.50mm......RK370SD-5028....35000
以上是常见的航模370马达的参数,004一代的原配就是7.2V的镍氢+RK370SD-4533,比4530多了3匝而已,除了4合一和马达质量问题还可能是负载不匹配(减速比过小、齿距过小、大桨螺距过大)导致过流烧毁。
