Qingdao Diesel Generator Rental Company explains how diesel generators generate electricity

1. Overview

Electricity is one of the main energy sources in modern society. Diesel generators are mechanical devices that convert other forms of energy into electricity, powered by turbines, steam turbines, diesel engines, or other power mechanisms. They transform the energy from water flow, air flow, fuel combustion, or nuclear fission into mechanical energy, which is then transmitted to the generator and converted into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life.

Generators come in various forms, but their working principle is based on the laws of electromagnetic induction and electromagnetic force. Consequently, the general principle of their construction is to use appropriate magnetic and conductive materials to form magnetic and electrical circuits that induce electromagnetic power, thereby achieving the purpose of energy conversion.

The classification of generators can be summarized as follows:

Generator { DC Generator, AC Generator { Synchronous Generator, Asynchronous Generator (rarely used)

Alternators can also be categorized into single-phase and three-phase generators.

2. Structure and Working Principle

Generators are typically composed of components such as the stator, rotor, end caps, and bearings.

The stator is composed of the stator core, winding assembly, base, and other structural components used to secure these parts.

The rotor is composed of components such as the rotor core winding (or pole, yoke), retaining rings, center ring, slip rings, fan, and shaft.

The stator and rotor of the generator are assembled and connected by bearings and end caps, allowing the rotor to rotate within the stator, cutting magnetic lines of force, thereby generating induced electromotive force. This is then led out through the terminal connections and connected to a circuit, producing an electric current.

Electric Motor

Servo motors, also known as actuator motors, are used as actuating elements in automatic control systems to convert received electrical signals into angular displacement or velocity outputs on the motor shaft. They are divided into two main categories: DC and AC servo motors. Their primary characteristics are that they do not exhibit spontaneous rotation when the signal voltage is zero, and their speed decreases uniformly as torque increases. The rotors inside servo motors are permanent magnets, and the driver controls the U/V/W three-phase electricity to form an electromagnetic field. The rotor rotates under the influence of this magnetic field, while the motor's built-in encoder feeds back signals to the driver. The driver adjusts the angle of rotation of the rotor based on the comparison between the feedback value and the target value. The precision of the servo motor depends on the precision of the encoder (number of lines).
