Abstract

The invention discloses a magnetic induction variable-speed switch device comprising a frequency conversion circuit controller and a magnetic induction control switch. The frequency conversion circuit controller has a magnetic control integrated circuit. The magnetic induction control switch comprises a pedestal, a rotating shaft, a rotary knob, and a permanent magnet. The pedestal is fixed to a motor shell, and is provided with a through hole. The rotating shaft is rotatably arranged in the through hole. The rotary knob is fixed to an outer end of the rotating shaft. The permanent magnet is fixed to an inner end of the rotating shaft and directly faces the magnetic control integrated circuit. The permanent magnet is a rare earth magnet of which the magnetic induction intensity is 1 Tesla. By rotating the rotary knob, the permanent magnet rotates along with the rotating shaft to change the direction of magnetic field. Control on the magnetic control integrated circuit is realized as the direction of magnetic field changes, and thus the frequency conversion circuit controller controls the rotation speed of the motor. By using the device of the invention, continuous variable speed and reverse rotation of the motor can be achieved. The switch is a non-contact magnetic induction control switch, the overall design reaches the Chinese explosion-proof standard, and the safety coefficient is higher.

Description

technical field [0001] The invention relates to the technology in the field of electric pump switch devices, in particular to a magnetic induction variable speed switch device. Background technique [0002] Electric motors are the largest consumers of electricity. They account for about two-thirds of industrial power consumption and about 45 percent of global power consumption, according to a new analysis by the International Energy Agency. Lighting is a distant second, consuming around 19%. This means that almost every second of electricity produced comes from the operation of electric motors in the power plant. [0003] At present, in order to change the speed according to the needs of the actual situation, the current motor is equipped with a control switch, and the speed of the motor is controlled by the control switch. However, the control switches currently used on the motor are all ordinary switches, which cannot be realized It has the functions of variable speed a...
