Three Phase 48V Permanent Magnet Alternator 200W This 48V three phase alternator is a compact, gearless permanent magnet generator designed for stable lowspeed power generation. Its rare earth NdFeB magnets and copper windings deliver consistent output and efficient conversion in a small, robust package. Key benefits Stable, efficient output: NdFeB permanent magnets combined with precision copper windings provide steady power and an 85 percent conversion efficiency. Gearless direct drive: Lowspeed, gearless design enables direct coupling to turbines or shafts at rated speed, reducing mechanical complexity and maintenance. Durable construction: Aluminum alloy housing with surface treatment and a carbon steel main shaft offer longterm mechanical strength and resistance to wear. Effective cooling and low startup torque: Special rotor design minimizes torsion at startup with starting torque below 0.1 Nm and supports good heat dissipation for reliable operation. Simple maintenance: Lubrication via addable grease and H class insulation make routine servicing straightforward.
