Embodiment Construction

[0044] The block diagram of the DC drive device of the asynchronous motor is shown in Figure (7), where 1 is the power supply, such as a battery; 2 is the motor and the detector for detecting its current, speed, etc.; 3 is the controller, and there are Memory, comparator, amplifier and other components are used to store the set current mode, current cycle, amplitude and other data. Receive the real-time signal of the motor running from the detector, compare it with the stored set value, and issue instructions for corresponding operations according to the comparison result. There are also devices and corresponding displays for manually setting the cycle (speed), size, phase sequence (steering) of the current in the controller, and it has a program to provide motor starting, braking and other operations; 4 is the driver, that is, the driving device of the main circuit.

Abstract

The invention relates to a direct current (ZLDL) asynchronous motor which describes a method for modifying an alternating current (AC) asynchronous motor driven by an AC voltage source into a direct current (DC) asynchronous motor driven by a direct current source. The direct current (ZLDL) asynchronous motor provides a theoretical basis for developing high-quality low-price asynchronous motor speed regulators and vehicle motors. The direct current (ZLDL) asynchronous motor gives the waveform of normal work direct current of the DC asynchronous motor and the block diagram of a drive for generating the current waveform.

Description

technical field [0001] The invention explains how to directly drive an asynchronous motor with a direct current source. This involves two key issues: one is what kind of DC current can generate a rotating magnetic field that rotates at a uniform speed when passing through the stator winding of an asynchronous motor; the other is how to generate the required DC current. The main purpose of the present invention is to lay a theoretical foundation for the design and manufacture of DC asynchronous motors, so as to provide economical and practical motors with excellent performance for electric vehicles. It can also explore the application prospects of DC asynchronous motors in the fields of electric cars, electric locomotives, and AC motor speed control devices. Background technique [0002] It is an urgent task to develop an electric vehicle with excellent performance and low cost, which has unlimited business opportunities. There are two main problems to be solved and difficu...
