How to Test the Connection of 3-phase Alternator & Controller

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators.

Next ,we will talk about how to test the connection of three phase alternator and controller by using ATO 300W alternator and ATO wind controller (12VDC 300W).

Features of alternator

• Excellent heat dissipation due to the Aluminium alloy outer frame and special internal structure.
• High efficiency and Low mechanical resistance energy loss.
• Generator is designed using speciallted material and treated to resist corrosion and oxidation.
• Low start up speed due to low cogging and resistive torque design.

How to test?

1. Using motors to drive generators to simulate wind turbines.
2. The 3-phase output terminal of the generator is directly connected to the input terminal of the controller.
3. Slowly accelerate the gernerator, and you can see that the controller voltage gradually rises to the 12V battery chargeable range.

At present, ATO generators and controllers have been widly used in wind power and hydropower. More information by watching the video below.
