Polar Power designs and manufactures its own alternators; we sell complete generators and not alternator kits.

Because our alternators and controls are designed to fit directly on specific engines and engine models of specific build configurations we are unable to sell and support alternator kits. Under certain programs involving quantity we will consider selling alternators kits under a franchise contract.

Design for Performance

  • Available in voltages of 12 to 500 Vdc
  • 32 pole high frequency design provides low electrical ripple
  • Higher frequency design provides compact and lightweight performance
  • Direct engine mounting further enhances the compact and lightweight design
  • Conventional 3 phase stator lowers assembly cost
  • NdFeB Magnets for high efficiency
  • Class 220 C magnetic wire for long and service life
  • Anodized type III process for aluminum parts
  • Nickel plating for steel parts
  • Stator is varnished
