Genmac Land TR 27-30
Cardan Generator
4 Compound Poles

Genmac Land - 4-pole Compound Cardan Generator for Tractor use

The Genmac Land generator is a cardan generator designed for agricultural use. Generator which, combined with a tractor for agricultural use , uses the power of the tractor to generate electricity.

The Genmac Land cardan generator can be used in agricultural activities where energy is required to power electrical equipment , such as irrigation pumps , agricultural machinery or lighting .

Perfect for agricultural companies , work in wooded or forestry areas , greenery maintenance , livestock farms and for users who own a tractor and want to exploit the power generated by the vehicle to provide energy. and power electric tools, in areas where it is not possible to access the terrestrial electricity grid or in the event of an emergency/blackout.

Operation of the cardan generator

However, it is important to choose a cardan generator with cardan connection suitable for the tractor . A cardan-driven generator set is made up of a frame on which an alternator is positioned which can be connected to the tractor by a special speed multiplier on one side. On the opposite side it is equipped with an electrical panel with power sockets.

The cardan generator sets are operated with a cardan coupling , thanks to the action of the PTO power take-off . (Power Take Off) of a tractor for agricultural use, through direct coupling to the cardan . Everything is fixed on a metal frame to protect the alternator and allow for more comfortable use.

The operation of a cardan generator can be summarized in these points:

• Connection to the tractor : The cardan generator is mechanically connected to the tractor engine, through a belt or a drive shaft. This allows the tractor engine to transfer its mechanical energy to the generator;
• Energy transformation via magnetic induction : the generator receives mechanical energy from the tractor and transforms it into electrical energy that can be used for electrical equipment, pumps, engines or agricultural equipment.
• Tractor speed adjustment : there is a correlation between the energy generated by the motion of the tractor and the power emitted by the cardan generator. Accelerating or decelerating the tractor can affect the frequency and voltage of the electricity produced.

Equipped with a compound or AVR type current regulator , it requires a minimum value of tractor engine power and input rpm to allow operation; the multiplier with protection will then supply the alternator with the energy necessary to create the electric current.

Cardano Generator with Compound

The compound system of a generator is a mechanism that keeps the output voltage stable despite variations in the load.

In short, the compound of a generator emits a correction signal for the voltage of the machine which can be positive, if the function of the compound is to increase the voltage or negative, if the voltage is decreased.

The compound is fundamental for the operation of a cardan generator which is combined with electrical appliances and equipment powered by the generator.

4 pole alternator

Alternators have 2 or 4 poles . The 2 poles are suitable for 3000 rpm engines, while the 4 pole alternators are for 1500 rpm engines.
