Model Description: take ElecmamaM-184G for example

Elecmama — indicates generator brand from Yangzhou Yongcai Machinery Co., Ltd
M — indicates Marine Generator
18 — indicates the frame size of the generator (160, 225, 280, 315, 355, 400, 450, 500, 560)
4 — indicates the generator is 4 poles generator
G — indicates core length


More Technical Features:

1). a failure rate of less than 0.2%. Generators enjoy a high reputation for reliability and long service life.
2). Stator patented technology
The end of stator coils adopts H insulation film and the insulating along the root of the wire for uniform half-stack package according to the different coil ends extruding from the notch, to improve the dielectric strength and mechanical strength of the end part. The ends of the stator and each bundle of the coil have been processed; the lead end of each bundle of coils has been reshaped. At the end of stator of each generator, an insulating end cap is added, and each bundle of re-shaped coils is effectively fixed to the insulating end cap, so that the end coil forms an integral with excellent strength, to effectively prevent and withstand the impact from sudden load and short circuit, which may then cause the stator end to fall apart.
3). rotor professional technology
rotor coil wire, triple insulated structure:
Bottom: H-class insulation film stack package
Middle: insulated glass package
Outside: high-quality insulating paint soaking, drying
Effectively improving the inter-turn and inter-layer insulation of the rotor, as well as the moisture and corrosion resistances, the service life, reliability, and environmental adaptability of the generator. Particularly suitable for being used in high humidity and heat, subtropical, island, chemical, dyeing and other harsh environments
4). Rotor segment V-shaped wing support block
For the expansion and elongation of the generator rotor copper wire due to high temperatures has been taken into consideration in the initial design. Segmented support block design is adopted and sufficient space is reserved to prevent damage the insulation caused by the deformation of the copper wire due to thermal expansion and cold shrinkage, which can result in the burning of the generator.
