BLDC Motor Functions
- twenty pairs of poles hello-torque motor design Precision engineered for greatest strength conversion Precision well balanced rotor, smoothness for greatest dependability and greatest RPM
- Several safety characteristics: Lower voltage lower-off defense, more than-warmth security, throttle sign decline security
- Lengthy steady overall performance: No mistake time lasts long for 2700 hrs at 24V voltage and 60A current functioning problems.
- Fulfill National Armed forces regular, EMC, FCC,CE and so on.
- Suited for industrial and specialized drones( Multi-rotor, fixed wings drones)
- Shaft: Higher hardness, prolonged lifespan( Particular stainless steel)
- Housing: 7075 collection aerial specialist large hardness aluminum alloy, far more pricey than the 6000 sequence with reduced alloy hardness and the screw effortless to unfastened.
- Magnet: special long lasting magnet with very good functionality and exclusive heat resistance.
- Coil: Higher purity copper windings maximizes performance CZPTed from Japan with very good overall performance, large warmth resistance Undertake vertical varnish technological innovation to make the wire thickness even
- Bering: CZPTed(Not-refurbished)
- Iron main: CZPTed, exclusive silicon metal sheet.
