Abstract

The invention creatively discloses a laterally controlled pole-changing three-phase motor system. According to the laterally controlled pole-changing three-phase motor system, built-in control information of an active magnetic control system lidesheng (14) is output via an active magnetic control system lidesheng control port 1 (9) and via an active magnetic control system lidesheng control port 2 (13) respectively and power supply of the excitation solenoid (1) is realized through an input port 1 (7) and an input port 2 (10) respectively; the excitation solenoid (1) is electrified to generate a polarized magnetic field with a variable N/S; the variable polarized magnetic field generated by the excitation solenoid (1) and a rotor synchronously cut a motor solenoid (3); the motor solenoid (3) subjected to cutting of magnetic lines of force generates a drive magnetic field; and a power supply input inputs three-phase electric energy through a power supply input port 1 (15), a power supply input port 2 (16), a power supply input port 3 (18), a power supply input port 4 (19), a power supply input port 5 (20) and a power supply input port 6 (21) respectively, so that the targets of changing of a rotating speed within a cycle and adjusting of the stability of a motor in a pole-changing manner are achieved.

Description

technical field [0001] The invention relates to a side-controlled pole-changing three-phase motor technology for multi-field applications such as active magnetism, in particular to a device that uses a side I-shaped magnetic conductor to control the forward and reverse direction of the wire-wrapped current and the magnitude of the wire-wrapped current; , drones, electric vehicles, fans, air compressors and other electric devices driven by unequal speeds (referred to as "side-controlled pole-changing three-phase motor system"). Background technique [0002] At present, the frequency converter used in motors is composed of electronic components, which are easily burned by high current and overload, and are directly related to ambient temperature and humidity and are easily damaged; the frequency converter is an online frequency conversion mode, and the product cost is high; the frequency converter and The price of the motor of this power is similar and higher.
