Abstract

The invention is suitable for the motor field, and provides a quick response linear motor, a control method of a quick response linear motor, and an integrated control chip. The quick response linear motor comprises a housing, a stator, a rotor, and a supporting shaft. The stator comprises a conductive sleeve, and the rotor comprises a supporting skeleton and a driving coil used for generating a driving magnetic field along the axial direction of the supporting shaft. The conductive sleeve of the stator of the quick response linear motor can be produced by adopting conductive materials, and the supporting skeleton of the rotor is provided with the driving coil in a coiled manner. When the current pulse passes through the driving coil, the induced current can be generated by the stator, and the magnetic field opposite to the above mentioned driving magnetic field can be generated, and then the rotor can be driven to move, and therefore the quick response can be realized. When the large instantaneous pulse current passes through the driving coil, the large power can be generated. The coiling direction of the driving coil is arranged around the axial direction of the supporting shaft, and the stator is in the shape of a sleeve, and therefore the size of the rotor can be small, and then the size of the linear motor is small.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a fast-response linear motor, a control method and an integrated control chip for the fast-response linear motor. Background technique [0002] Linear motor is also called linear motor. Its principle is: linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and developed into a plane. The side evolved from the stator is called the primary, and the side evolved from the rotor is called the secondary. In practice, the primary and secondary are manufactured to different lengths to ensure that the coupling between the primary and secondary remains constant over the required travel range. Linear motors can be short primary and long secondary, or long primary and short secondary. When the primary winding is connected to the...
