Problems solved by technology

In the AC-DC-AC conversion inverter, the conduction angle of the thyristor can be provided, but in the AC-AC conversion inverter, the signal cannot be provided
Therefore, the above methods will be affected by the installation conditions and the working mode of the inverter. At the same time, other signals are required to modify the set engine speed.

Embodiment Construction

[0013] The implementation of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 It is a block diagram of the system configuration of the generator speed regulating device of the present invention. The engine 1 drives the generator 2, and the stator of the generator 2 is wound with a three-phase main winding 21 with output load and a single-phase auxiliary winding 22 for control. A stepping motor 11 for adjusting the throttle opening is installed on the carburetor of the engine 1 . When the rotor is driven to rotate by the engine 1, the single-phase auxiliary winding 22 of the generator 2 outputs alternating current with a frequency corresponding to the engine speed, and the three-phase main winding 21 also outputs a three-phase alternating current with a frequency corresponding to the engine speed, simultaneously generating electricity The output voltage of engine 2 also changes with the change of engine speed. The t...

Abstract

The invention relates to one motor inverse device and its control method wherein, its device can rapidly trace its load according to its size and motor rotation speed to modify its set value through judging the motor rotation stability. The method comprises the following steps: dividing the load range and testing the motor current change to determine its direct operation steps and direction according to the load and gas gate to adjust the motor gate into pre-set position.

Description

technical field [0001] The invention relates to motor control technology, in particular to an inverter control generator. Background technique [0002] In inverter-controlled generators, the engine speed needs to be adjusted to meet the requirements of low noise and low fuel consumption. Chinese patent application CN03120778 discloses a method for controlling the engine speed according to the load, and the set engine speed is modified by detecting the temperature of the medium in the closed soundproof box. For the window-opening (no closed soundproof box) inverter-controlled generator, there is a certain difference between the temperature detected by the temperature detection element and the actual temperature of the generator. [0003] Chinese patent application CN1407223 discloses a method for controlling the engine speed according to the load, and the set engine speed is modified by detecting the conduction angle of the thyristor in the inverter. In the AC-DC-AC convers...
