Method for enhancing output torsion of motor

Abstract

The invention discloses a method for enhancing output torsion of a motor; a stator and / or a rotor of the motor is annularly provided with a plurality of permanent magnets in a spacing distance, the stator or the rotor is provided with the same number of electromagnetic components corresponding to the permanent magnets, the current is switched on or off in sequence on the plurality of electromagnetic components, so that the electromagnetic component with the current switched off shields the permanent magnetic force of the corresponding permanent magnet, the electromagnetic force generated by the electromagnetic component with the current switched on and the permanent magnetic force generated by the permanent magnet on the stator or the rotor are superposed to enhance the magnetic force ofthe magnetic field of the motor, so that the output torsion of the motor is enhanced. The method in the invention is reasonable and ingenious in design, and the magnetic force of the magnetic field isincreased through superposition of the permanent magnetic force and the electromagnetic force, so that the output torsion of the motor is enhanced, the problems that the motor is small in power, lowin torsion and large in energy consumption are solved, more power is saved, the magnetic shielding body ensures that the magnetic fields of the stator and the rotor do not interfere with each other, the change of the magnetic field is uniform, own vibration of the motor is reduced, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of permanent magnet DC motors, in particular to a method for enhancing the output torque of the motor. Background technique [0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor can be divided into a brushless motor and a brushed motor according to whether it has a brush or not. In the traditional motor, the magnetic field can only be generated by the permanent magnet installed on the stator or the rotor, and because there is no magnetic shield, if the stator and the rotor are equipped with permanent magnets at the same time, the magnetic field interferes with each other, so that the rotor cannot rotate, resulting in motor failure. The work efficiency is low, the energy consumption is large, and the goal of environmental protection and energy saving cannot be achieved. Therefore, it is of h...
