Abstract

The creative invention discloses an internally-controlled excitation pole-changing motor. The internally-controlled excitation pole-changing motor is jointly composed of an excitation coil 1, an inner I-shaped magnetic conductor 2, a stator coil 3, an outer stator magnetic conductor 4 and an active magnetic control system lidesheng 14, wherein built-in control information of the active magnetic control system lidesheng 14 is used for supplying power to the excitation coil 1 respectively by output of a control port 1 of the active magnetic control system lidesheng 9 through an input port 7 and by output of a control port 2 of the active magnetic control system lidesheng 13 through an input port 10, the excitation coil 1 generates a polarized magnetic field with variable N / S after energization, the variable polarized magnetic field generated by the excitation coil and a rotor synchronously cut the stator coil 3, the stator coil 3 generates AC voltage by cutting magnetic lines, complete occlusion is output respectively through an output port 15 and an output port 16 to generate a cutting magnetic field, and thus, the purposes of speed regulation and driving by means of reverse cutting magnetic field are achieved.

Description

technical field [0001] The present invention relates to an internally controlled excitation pole changing technology for multi-field applications such as excitation pole changing, and in particular to a device that uses an internal I-shaped magnetizer to control the magnitude of the current in the excitation wire; And other devices that use the drive motor and adjust the speed at any time (referred to as "internal control excitation pole-changing motor"). Background technique [0002] At present, the motors directly control the current or voltage and frequency of the main line package on-line. The frequency converter is mainly composed of electronic components. Damage; the frequency converter is an online frequency conversion mode, and the product cost is high; the price of the frequency converter and the motor of this power is similar and high. Contents of the invention [0003] The invention provides an internally controlled excitation pole-changing motor technology aim...
