Masuma alternators are designed for 12V vehicle electrical systems and deliver a stable output voltage of approximately 14 volts, ensuring reliable power supply under all operating conditions.

Key features of Masuma alternators:

  • Compact, high-efficiency design with an internal dual-blade fan integrated into the rotor. This setup provides effective cooling, reduces overall weight, and helps minimize noise during operation.
  • Durable construction using high-quality components and heat-resistant polymer materials in the rotor to withstand elevated engine bay temperatures.
  • Thorough testing of every unit, including durability trials with repeated acceleration and deceleration cycles, as well as output performance measurements under various load conditions.

Each alternator product page provides detailed specifications, including:

  • Output voltage and current
  • Voltage regulator connector type and pin configuration
  • Pulley parameters (outer diameter, number of grooves)
  • Presence of a freewheel belt pulley (overrunning pulley)
