Problems solved by technology

The problem is that the motor can only use DC motor, the electronic control system is complicated, and the cost performance is not high
[0006] Chinese patent 201120203379.8 discloses an energy recovery control system for electric vehicles. The energy generated during the deceleration process can be recovered by separately setting the driving motor and the generator, but the generator is idling during driving, neither driving nor Power generation, there is still a situation of equipment and energy waste
The problem is that the winding coil only works when recovering no-load energy, but does not act when driving

Embodiment Construction

[0025] like figure 1 Among them, a device for potential energy load and energy recovery and reuse,

[0026] Including the driving motor M1 and the feedback motor M2, the feedback motor M2 is mechanically connected with the output shaft of the driving motor M1, and is used to drive the load at the same time, that is, the driving motor M1 and the feedback motor M2 output power at the same time when driving the load; figure 2 , 3 Among them, the driving motor M1 can use an AC motor or a DC motor, so that the configuration is more flexible, and the use of an AC motor can reduce the overall cost of the device.

[0027] The dragging motor M1 is independently electrically connected to the dragging motor driving device; the said dragging motor driving device is powered by an independent power supply. That is, the electrical control systems of the drive motor and the feedback motor are independent and do not interfere with each other.

[0028] The regenerative motor M2 is a DC seri...

Abstract

The invention relates to a potential energy loading and energy recycling device which comprises a dragging motor and a feedback motor, wherein the feedback motor is mechanically connected with an output shaft of the dragging motor, and is used for simultaneously driving a load; the dragging motor is separately and electrically connected with a dragging motor driving device; the feedback motor is a direct current (DC) series excited motor; and the feedback motor is electrically connected with an energy storage unit, and is used for recovering the energy and providing electric energy when being used for driving the load. According to the potential energy loading and energy recycling device, a composite motor is formed by the dragging motor and the feedback motor, so that the power needed by dragging can be met, the feedback energy can be recovered and applied during reverse dragging, the equipment manufacturing cost and operation cost are reduced, and the effects of saving energy and reducing consumption can be achieved.

Description

technical field [0001] The invention relates to the field of motor driving and recovery of regenerative energy, in particular to a device suitable for potential energy loads and energy recovery and reuse of hoisting machinery and various elevators. The device of the present invention can also be used in mining machinery and electric transport machinery. Background technique [0002] With the development and progress of society, people pay more and more attention to energy saving and environmental protection, and various industries have carried out a lot of research and application in energy saving and environmental protection to varying degrees. Motor drive is widely used in engineering hoisting and transportation machinery. It is of positive significance to study the recovery and application of potential energy load or braking regenerative energy in engineering hoisting and transportation machinery. [0003] In traditional engineering lifting and transportation machinery, ...
