Abstract

The invention discloses an intelligent motor control system, which is mainly designed for solving the problems existing in the conventional motor controller. The intelligent motor control system comprises a power supply and a direct current motor, wherein a current input end of the direct current motor is connected with the power supply or connected with the power supply through a direct current-three phase alternate current conversion module; the system also comprises an energy storage inductor, a relay current circuit and a speed regulation switch; the energy storage inductor is arranged between the power supply and the direct current motor or between the power supply and the direct current-three phase alternate current conversion module; the two ends of the relay current circuit are connected with the two ends of the power supply respectively; and the speed regulation switch is connected with one end of the power supply. The system can reduce the impact of the circuit on the motor, reduce the temperature rise during the running of the motor and effectively improve the working efficiency of the motor so as to fulfill the aim of energy conservation.

Description

technical field [0001] The invention relates to the field of motor speed regulation control, in particular to a speed regulation control system of a DC brushed motor and a DC brushless motor. Background technique [0002] With the continuous development of science and technology, DC motors are widely used in the field of industrial automation control, such as various automatic testing and sorting equipment, various assembly line feeding control systems and so on. In addition, DC motors are used in people's daily life, such as household appliances, children's electric toys, electric bicycles, electric vehicles, and various occasions that require motion control. [0003] DC motors are divided into brushed DC motors and brushless DC motors. The magnetic field generated by the stator has the same frequency as the magnetic field generated by the rotor. The motor itself of the brushless DC motor is an electromechanical energy conversion part. In addition to the motor armature and...
